Need to clean inkjet heads on Epson 740

[wylbur37]

I have an Epson 740 inkjet printer.

After not using it for a while, I discovered that the inkjet nozzles
were apparently clogged to the point where the "head cleaning routine"
was of limited usefulness.
The printouts show signs of missing lines and "bleeding fibers"
indicating the presence of accumulated residue around the nozzles.

I'd like to be able to free the print head carriage assembly
so that I can wipe the front of the nozzles and clean them,
but I can't find the right screws to remove.

The Epson website has various manuals to download but they don't seem
to have the one that I need. Their Product Information Guide on setup
and testing (sc740_pg.pdf) mentions (on page 15,
under Related Documentation) the "TM-SC467 Epson Stylus Color
440/640/740 Service Manual", but that publication is apparently
nowhere to be found on their website.

Can someone either
(a) explain how to remove the print head assembly so the nozzles can be
cleaned or
(b) mention a website where the necessary documentation is available
for download or
(c) if you have the document, send me a copy via email as an attachment.


Thanks for your help.

The Epson inkjet printer is a field replaceable item. You throw away
the printer and replace it with another at the same or less price of a
set of ink cartridges for it. If you're smart, you'll get a printer
that has the nozzles built into the cartridge, such as the HP deskjet,
or similar.

I'm really serious about this. At work, the teachers go on vacation in
the summer, and when they come back in the fall, the Epsons are all that
way. So we just tell them, the Epson is not a district standard
printer, so we don't support it - sorry. If you get a new one, the
district standard is HP.

Which IMO just tells us quite a bit about the mentality of Teachers and
supply coordinators in charge of our children. The total cost of ownership
for an HP is usually twice that of Epson with lexmark leading by a whopping
margin. So Teachers don't even know about a little preventative maintenance.
Whip out the plug in mid-flight -prior to that looong vacation - spray in a
little Windex: some on the docking sponge and its done.
If you get really religious and cost conscious then a few spent cartridges
and a preventative print , again prior to vacation will keep them all
working just fine. That may not be within the teacher's remit or
intelligence but it works.
In any case vacation School buildings are normally used by parents and other
recreational classes during vacation times so why aren't they using the
printers ? Strikes me your costs could be halved and the tax payer's money
as well with a little thought and planning. Are you sure the motivation for
HP is cost.

HP is cost.

You're using your experiences to judge someone else's situation, which
is not a valid judgment. The full-time teachers have a 6 by 10 ft
'office' (more like cubbyhole) which is theirs to lock up all summer
long, contrary to your judgment.

As for cost, well, you have to weigh in the other factors such as the
time it takes for the staff such as our helpdesk staff to do whatever
has to be done to get the teacher a page properly printed out. If we
had to go over with a bottle of windex and do as you suggested, it would
cost us at least a whole additional person full-time, because there are
hundreds of printers out there. And if you think that it's possible to
get a teacher to do that cleaning job, you haven't been in this
situation. Those teachers get paid a lot more than we do. And they get
off the whole summer, too.

Suffice it to say that if the teachers can talk their department head
into buying a 2 thousand dollar HP color laser printer and supplying it
with a new set of toner cartridges every few months at a cost of several
hundred dollars each, they can easily afford a few ink cartridges. And
new Epson printers, when the old ones get clogged up. We have a whole
warehouse of PCs and monitors, hundreds of them, setting there waiting
to be scrapped, and that's just a year's accumulation. What's the cost
of a few printers in the grand scheme of things? Nothing, especially
when compared to labor costs. The teachers won't deal with these
details, that's why they have us helpdesk peons. I was the first elec
tech the district hired, now 2 dozen years later we have dozens of
techs, just to deal with these user issues, and each tech gets paid the
cost of a couple cartridges a day. So why not throw inkjet printers at
the problem if it will save having to hire another tech. We used go
over and undo and reinstall the printer after the Lusers screwed around
with the printer setup, until we got wise and took away all users' local
administrator priveleges. Now they can't goof it up quite as bad and it
saves a lot of the techs' time. We have nicknames for certain
departments where there are those Lusers that have a propensity for
screwing things up. The techs call one dept "HM2", meaning High
Maintenance #2. They're not the worst; that title's reserved for HM1.
:o)

Believe me, I'm all for giving each user his own printer, that way I
wouldn't have to pull new cat5 cable to the big networked HP printer
they buy for the department. But they don't and I do, so that's called
Job Security. And the cost of a printer or even a PC is nothing
compared to the amount of labor and downtime wasted by a wave of virus
infections such as klez. Now, I can't even send someone a .ZIP file
because the email system rips it out and tells the recipient that it's
possibly a virus. But you have to look at the good side. All those
.ZIPs that don't get thru are no longer printed out, so it saves on ink,
paper and printers. ;-)

No, I wouldn't want to, because you wouldn't pay me 28 bucks an hour to
do so. Besides, we full-time employees don't work on the printers, we
have a vendor send a field tech over for one day a week, and we pay them
a bundle of money just for that. I'm sure we wouldn't want to pay them
to have him here more just to clean print heads. We've scrapped a whole
lot of laserjets because the cost to repair is more than the printers
are worth, so we just buy a new one.

And if you think this is expensive, you should see the bills for the
Xerox monster they have out in the publications center. It looks like
this, but I think it's an earlier model.

The Western World is despised by envious cretins who cannot, or will not,
admit the benefits of concepts like sanitary water systems. Their faulty
logic romanticizes the noble savage , wiping his ass with a stick and a pile
of sand, and earning his progeny the reward of a 30-year life expectancy.

That might explain why the US is rapidly running out of potable water,
and is now trying to negotiate to get more from Canada.

Talk about not learning about the value of not spoiling one's own nest!

Believe me, in spite of your arrogant belief that Western Culture has
such great benefits, they pretty much invented the cancer epidemic, and
could learn a great deal from more "primitive" cultures about not
exhausting resources beyond the ability of replenishment. Much of
"Western Civilization" doesn't have a clue about what truly encompasses
"sustainable lifestyles".

How long do you honestly believe the US could survive, for instance, if
the population was forced to produce it's own food, supply it's own
energy sources, building materials, minerals and metals, and have to
cope with its own waste?

Why don't you swear off taking any materials you currently consume from
those "noble savages" with their "30 year life spans" and see what you
have left in your cultured society? Then we'll see who is the envious one.

I had an old Epson Stylus II that never dried up, even after months of not
using it. Later I had a newer Epson and was dissapointed to find it would
dry out after only a couple weeks of not printing.

Here's a post from a while go - a friend of mine has tried it successfully :

The symptom is missing horizontal lines
through text or graphics -- or no print at
all. This occurs when the water based inks
dry at the print heads in amounts that the
head cleaning routine cannot dislodge.

The newer Epson Stylus Color series print
heads are particularly affected.

It can happen whether you refill your inkjet
cartridges or not.

One contributing factor is turning off the
printer from a power bar. This prevents a
complete shutdown and docking of the heads
at their docking stations. You will notice
some activity even after turning the printer
off by its switch, as it continues to take a
trickle charge.

To unclog the heads:

- Run 3 cleaning cycles from the Epson
Utility

- Turn off printer, and restart in Test
Print mode

- When cartridges/ print heads are at
extreme left of carriage, quickly spray 3
shots of Windex or Ammonia onto docking
station(s) affected, and turn off printer
for 5 minutes

- Repeat process as needed until perfect
test prints are restored - usually 2
procedures

We've saved 14 printers this way.

I was going to post the Ammonia suggestion. It worked for me, and the
printer concerned, was still working two years latter when I sold it.
It is very effective indeed.
It is worth realising that the removing the head won't really help, since
the blockage is inside the nozzles, and not something external that can be
wiped away. The cleaning sponges at the docking end of the carriage, come
directly into contact with the heads, and cleaner on here works, without
risking destroying the alignment of the system.
It is worth also saying, that the Epson heads are far less prone to this,
than the HP cartridges, and when you have been through 30+ HP cartidges at
£20 or more a time, in each case replacing them before more than a quarter
of the ink is used, the Epson system does not seem bad. I have never
successfully got an HP cartridge to clean.

The HP cartridges may be expensive, but they don't clog up as often in
as Epsons in my experience, and when they do, all you have to do is
replace the cartridge, and not waste tons of time on trying to get it to

I have never successfully got an HP cartridge to clean.

But you can remove the whole cartridge and set the business end on a
sheet of paper towel wetted with whatever you want to clean it with. Or
even put the heads in a shallow liquid, like in a lid from a jar or
bottle.

And if you're against tossing the printer cartridges and putting new
ones in, then youi might consider what some people do. They just buy a
whole new HP printer on sale for $70 or so, with cartridges, and give
the old one to a friend or the kids or whatever.

And save a lot of money by refilling the cartridges. Epson uses a chip
in heirs to thwart the refills so they can sell more cartridges. But
the pirates sell kits that have already bypassed those.

was of limited usefulness.
The printouts show signs of missing lines and "bleeding fibers"
indicating the presence of accumulated residue around the nozzles.

Here's a post from a while go - a friend of mine has tried it
The symptom is missing horizontal lines
through text or graphics -- or no print at
all. This occurs when the water based inks
dry at the print heads in amounts that the
head cleaning routine cannot dislodge.
The newer Epson Stylus Color series print
heads are particularly affected.
It can happen whether you refill your inkjet
cartridges or not.
One contributing factor is turning off the
printer from a power bar. This prevents a
complete shutdown and docking of the heads
at their docking stations. You will notice
some activity even after turning the printer
off by its switch, as it continues to take a
trickle charge.
- Run 3 cleaning cycles from the Epson
Utility
- Turn off printer, and restart in Test
Print mode
- When cartridges/ print heads are at
extreme left of carriage, quickly spray 3
shots of Windex or Ammonia onto docking
station(s) affected, and turn off printer
for 5 minutes
- Repeat process as needed until perfect
test prints are restored - usually 2
procedures
We've saved 14 printers this way.

I was going to post the Ammonia suggestion. It worked for me, and the
printer concerned, was still working two years latter when I sold it.
It is very effective indeed.
It is worth realising that the removing the head won't really help,

since

Post by Roger Hamlett
the blockage is inside the nozzles, and not something external that

come

Good point.

It is worth also saying, that the Epson heads are far less prone to

this,

than the HP cartridges, and when you have been through 30+ HP

cartidges at

Post by Roger Hamlett
of the ink is used, the Epson system does not seem bad.

The HP cartridges may be expensive, but they don't clog up as often in
as Epsons in my experience, and when they do, all you have to do is
replace the cartridge, and not waste tons of time on trying to get it to
clean and work properly as the Epson requires. We've never had as
many problems or complaints with the HPs as we've had with the Epsons.

Interesting. The exact opposite of me. We have over 300 printer in the
company I work for. The running costs for HP equivalent models, worked out
over double that of the Epsons, with a hige number of 'early replacement'
cartridges. We have had just two Epson's develop clogged nozzles, and both
cleared.

I only hear cleaning cycles, if the printer has been switched off, or left
idle for a couple of days. Normally responses are instantaneous. The HP
units also do a clean if left idle.

Yes, and then the cartridge no longer gives the fine ink dots it used to.
The quality degrades massively. The same is true after most refills...

I suspect that this explains a lot. The two machines that did develop

cartridge, by one person...

And the one significant thing that separates you from the educational
establishment is that word business.They don't feel the purse strings
tightening and when not held accountable , plain just don't account.
Looking through their setup it is quite asy to imagine that it would pay
them to have a spending ceiling set and have one person appointed to
maintain and renovate printers.
If their on call Tech is from the supplying company I wonder what he would
recommend when refurbish or a new replacement is the decision :-)

A solvent for dye based inks is commonly used. Windex (Windolene UK) is a
window cleaning fluid which disperses encrusted or dried ink: Some of the
newer shower dispersant cleaners work equally well.
Firstly try a few drops on the docking sponge area which is where the heads
sit when parked.
Whipping out the mains plug in mid flight will expose this.
With a cotton bud introcude a few droplets on the piercing splines and the
sponge.
In real determined blockage cases - fill a spent cartridge with the solvent
(Household ammonia 10:1 works as well) and print a few windy pages . Letting
it sit overnight can also ease it further.
The so called cleaning cycle is really priming of ink through the feeder
tubes and seldom cleans.

I found it is possible to clean the heads by filling an empty ink reservoir
with Alcohol and running the test print program many times. After 10 to 20
runs, it usually clears them out. Then put a reservoir with Epson approved ink
in and test. Repeat as needed. No guarantee. Depends on how badly it is
clogged!

I have a site that shows you how to do it, not to hard but you must also clean
up the parking station as that get paper dust and hair on it and dried ink,
that must be done so that the print head it covered and has a good vacuum..

I did mine by using this article, and the 740 works great afterwards..

I use a stuff called Spray and Wipe, 2mm in a flat tray, left the print here
face down in it for say one hour, then did it again, also move the head a
little up and down in the liquid, the liquid does not cover the head just the
face of it.

Then did it again with clean water, then dried it off with clean tissue

Yes here is the URL..

http://www.inkjetart.com/tips/cleaning/Image01.html

Please do make shore that the print head is place back correctly as the angle
of the head is important, the service manual refers to a test problem to set
the head up, but its also set by locking a screw, this does not get touched
when removing the hard.

My original 600dpi by 1200dpi '600' model ran for 2 years with a cleaning
cycle needed only rarely. Cartridges refilled by syringe. Used litres of
ink. Scrapped it as the flex PCB to the head 'fatigued'.
My next '740' model (same as yours) used to clog up if left for more than 10
days. (finer nozzles but cartridges still syringe refillable) Forced to
become an expert on nozzle cleaning, most of the nozzles could usually be
cleared. Finally blocked up and stayed blocked so I scrapped it.
Last model was the 'C82'. 1000's by 1000's of dpi. Chipped, non refillable
cartridges, huge cartridge costs. Blocked after 7 days of non use. Managed a
month and numerous cleaning cycles before heads permenantly blocked. Usual
unclog methods failed, ended up trying pressurised hot ammonia through the
nozzles (caused the nozzle driver I.C to melt :-). Scrapped it.
Pi***d off with Epsons, bought a next to nothing cost HP 3650. Quality not
brilliant, software is shite but have had it 10 months with not a single
problem, it has yet to block up, has taken none of my time and best of all,
the original cartridges can still be refilled, so costs are near zero.
Moral of the story is that Epsom just don't know how to make high dpi
printers that work in the real world.

I believe the true moral is that Epson will do most anything to get you to
buy their ink carts, possibly including not making too great of a printer.
Still, my Stylus II is still running and I bought a lifetime's supply of
real Epson carts on eBay for pennies, so it's a toss up which gives up
first.

I'm not playing the cross posting game, so I will contain my reply to
comp.periphs.printer, where I saw this.

You do seem to have your share of problems with printers.

Epson printers may experience more clogging than ones that have
removable replaceable heads, that would somewhat make sense, since those
other heads are replaced when the ink cartridges are.

The C82 uses pigmented inks, making them waterproof, pretty much fade
proof, but again, potentially more likely to clog, in very dry climates,
dusty environments, and if you do not shut the printer down properly.
Occasionally, the printer is not made to spec and the head capping is
incomplete, causing drying as well.

However, in the vast majority of cases, should the printer head clog, it
can be unclogged with the use of ammoniated cleaner. The success rate
(as long as you don't put hot pressurized ammonia through the head, that
is) is very high. Your situations are in the minority.

Once again, I would like suggest to people who read her and elsewhere
about removing the heads of Epson printers to clean them are being
poorly served by this advice.

The heads can be cleaned without opening the case, or removing the heads
in nearly every situation, and by opening the case or removing the heads
you subject the printer to a greater risk of damage.

I have instructions available for unclogging Epson printers which I
provide free of charge to anyone who requests it from me via my email
address.

Yes, fine, call it a hack. It's a hack that works well over 95% of the
time, and does so with almost zero risk of harming anything, and you
don't even have to own a screwdriver, or know how to open the case.

As I have stated dozens of times, I know of no cases of anyone who has
damaged their printer using the techniques I offer, I know of MANY cases
of people who have damaged BOTH their printers and their printer's heads
via removal and cleaning outside the printer.

While service depots may indeed remove the heads to clean them (and they
all do not, because I happen to know of several using the technique I
came up with) service depots not only have full Epson service manuals,
but also have access to Epson parts which they will gladly charge the
client for should they damage the printer during repair.

Further, I know of literally dozens of Epson printers which went to
service depots where they were informed "your printer requires new
heads" which I have either personally cleaned, or told the people how to
clean using the methods I suggest.

I have provided my Epson Cleaning Manual to thousands of people at this
point. I have made exactly ZERO financially from doing so. I don't
sell any Epson parts, I don't sell inks, I don't sell magic "cleaning
fluids". If it didn't work, you'd think by now the net would be full of
hundreds of complaints about how the methods didn't work, wouldn't you?
Instead, I get a steady flow of requests for the manual daily coming
from dozens of sources, (and I only post to this newsgroup). There is
even some guy on eBay selling what appears to be mainly a set of URLs on
Epson head cleaning for about $8 a pop.

Why do I do it for free? I do it because I am trying to keep perfectly
good printers out of the landfills and to protect people from
suggestions like yours, and web sites which suggest forcing fluid or air
through the heads which often lead to useless damaged printers. At
least once a week, I have to deliver an RIP for a printer to someone who
followed either the advice to remove the heads or forced liquid into the
heads and ended up with a completely dead printer head.

In cases of head clogs (not head failures, which unfortunately, I can't
help fix other than suggesting a head replacement) I can count on one
hand the number of people who have been unable to resolve the problem
after reading any applying the suggestions I provide.

Print head removal on Epson printers to clear clogs is potentially
dangerous to the printer and unnecessary, plain and simple. You can
call what I offer a hack. I'll call it effective.

I have an Epson 740 inkjet printer.
After not using it for a while, I discovered that the inkjet nozzles
were apparently clogged to the point where the "head cleaning routine"
was of limited usefulness.
The printouts show signs of missing lines and "bleeding fibers"
indicating the presence of accumulated residue around the nozzles.
I'd like to be able to free the print head carriage assembly
so that I can wipe the front of the nozzles and clean them,
but I can't find the right screws to remove.
The Epson website has various manuals to download but they don't seem
to have the one that I need. Their Product Information Guide on setup
and testing (sc740_pg.pdf) mentions (on page 15,
under Related Documentation) the "TM-SC467 Epson Stylus Color
440/640/740 Service Manual", but that publication is apparently
nowhere to be found on their website.
Can someone either
(a) explain how to remove the print head assembly so the nozzles can be
cleaned or
(b) mention a website where the necessary documentation is available
for download or
(c) if you have the document, send me a copy via email as an

attachment.

Thanks for your help.

My original 600dpi by 1200dpi '600' model ran for 2 years with a cleaning
cycle needed only rarely. Cartridges refilled by syringe. Used litres of
ink. Scrapped it as the flex PCB to the head 'fatigued'.
My next '740' model (same as yours) used to clog up if left for more than 10
days. (finer nozzles but cartridges still syringe refillable) Forced to
become an expert on nozzle cleaning, most of the nozzles could usually be
cleared. Finally blocked up and stayed blocked so I scrapped it.
Last model was the 'C82'. 1000's by 1000's of dpi. Chipped, non refillable
cartridges, huge cartridge costs. Blocked after 7 days of non use. Managed a
month and numerous cleaning cycles before heads permenantly blocked. Usual
unclog methods failed, ended up trying pressurised hot ammonia through the
nozzles (caused the nozzle driver I.C to melt :-). Scrapped it.
Pi***d off with Epsons, bought a next to nothing cost HP 3650. Quality not
brilliant, software is shite but have had it 10 months with not a single
problem, it has yet to block up, has taken none of my time and best of all,
the original cartridges can still be refilled, so costs are near zero.
Moral of the story is that Epsom just don't know how to make high dpi
printers that work in the real world.

Watson. I think it was yourself, (a post a couple of years ago) that caused
the scales to drop from mine eyes and guided me onto the true path of
printer righteousnous. :-).
