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.

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.


Thanks for your help.

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.

I have an Epson 740 inkjet printer.

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.

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.

This is wierd, but working.

Ever since this thing started screwing up, well it ran X well. but now, I know
the battery isreally bad, or is being overloaded. The thing that gets me is
that now it's actually running better.

I just now DLed a tune, and WHILE I was still on a P2P, it played perfectly,
and that ain't the first time since this happened.

If it continues to run like this (defaults loaded) damn. I shoulda took out the
battery whe I first got it. Hang on..............

Now I'm in this NG, on the "real" internet, playing an MP3 and just opened
Microsoft Word without the MP3 skipping.

It has never run this well before.

Wow.

Now I'm really scared, it has got to be ready to crash bigtime.

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.


Some info on Ajax Spray n Wipe, a Amonia/detergent based all purpose cleaner


http://new.thecleanmachine.co.uk/products/products418.aspx

Ajax, Colgate-Palmolive


Also use buy a local Printer repair shop, and used by them on Epson printers

Time to repair the vertical deflection circuits, check the electrolytic caps
in those circuits with an ESR Meter and replace those that check out of
tolerance. I'm sure you will find a few there that need to be changed.

Thanks for the solution. I think it is beyond what I know how to do
(because I don,t know what a ESR meter is or where those cerciuts are)
.. With this I can close the door on that tv. Not good news but at
least I don,t have to think about it anymore. I posted to find out if
the solution is something I could do and you provided the answer.
Thanks.

If it's one of the infamous MPF or MPG series drives, the problem is one
of the chips on the circuit board, not any of the mechanicals. Some

I spent 30 minutes watching a skilled tool and die maker try to resolder
the
radiator from his car with more and more heat and failing each time. I
finally asked him to let me try. I carefully cleaned all the parts, using
wire brushes and acid flux and washing it all thoroughly afterwards, a
process taking over 15 minutes. I then soldered it in less than 10
seconds.

It isn't just heat that does the job. It's a combination of materials,
cleanliness, flux and heat. I've soldered everything from litz wire to bus
bars and preparation is the key.
Click to expand...
You are very much correct except that it is heat that does the job. The
cleaning is necesary for the heat to occur where you want it.

BTW, if you want to test your soldering, try soldering pieces of flux
cored
wire solder together. If you are really good you can build your own mini
Eiffel tower.

I did before you said bad idea. When I oppened the TV and looked at
the adustment stuff, I found one in reference to vertical height. But
all it did was make the 2" inch black line smaller and stretch the
heads even more. I got it now, I will need to replace some related
parts.
