Hi!

Can anyone tell me how to clean a cartridge that is beginning to clog.. I
have a HP 7150 printer and the black cartridge is starting to give me some
problems. I have removed the cartridge and there is a lot s of dry black ink
around the printheads. It sometime smudge the paper when it print. Can you
help?

This worked for my clogged carts:
Get a shallow pan and boil some water. Take it off the flame and when it
stops boiling, place the printhead portion into the water. I suspended mine
with a bent wire hook so it wouldn't rest on the bottom of the hot pan.
Wait for around 30 minutes. Blot dry and see if it will work. Fwiw, the
person who told me about this was adamant about not being less than 30
minutes. I first tried 10 minutes holding it by hand but I was getting
burned. It didn't work. When I did it for 30 min, it worked. Good luck.

Just yesterday I had that problem with my 5550. I let my Black cart
get to low and it stopped printing, so I refilled. After, the cart
would not print. I ran it through the cleaning cycle...no joy. I
cleaned the print head with alcohol...no joy. As a last ditch effort
I ran the print head under cold water for a couple of minutes, dried
it thoroughly and lo & behold, it works fine.

Thank you for the info. I will try it today.

Try cleaning with Windex - WFM - spray or soaking - do not allow the
cartridge to run out of ink tho.... can be a prob to get restarted....

Hope this helps..

I ran the printhead under water in a dish (repeatedly emptied the dish then
refilling it as the color of the water changed from clear to inkish) to get all
the ink out then soaked the printhead in a dish of warm water for half an hour
and then in a dish of isopropyl alcohol 91% for 15 minutes and it made no
difference on my nozzle check. I got a couple of empty cartridges from my mom's
printer and refilled them and in an hour I'll see if that changed the game. If
not, I guess it's off to Best Buy for a new printer.

My nozzle check shows magenta & yellow doing the same kind of thing: missing the
bottom half of every other vertical column of horizontal lines. I have no idea
how to interpret what these nozzle checks mean unless it all looks good. I mean,
there is no Canon-made example of how the nozzle check page should look; so when
I first got the printer, it may have been "off" and I would have never have
known. And yellow is next to impossible to see anyway! What kind of light do I
need to see that?
 
It still has the same bad nozzle check, and a printout of a photo shows good
color, but there are very large (microscopically) visible horizontal lines
throughout the print, like it was only printing at half the resolution it is
supposed to (missing every other horizontal pass through).

It is probably an electronic problem. ?

Email (e-mail address removed) (Arthur Entlich) for his Epson printer
unclogging manual.

What worked for me on a tough clog on my Epson Stylus Color 785EXP
was rubbing q-tips dunked in isopropyl alcohol 91% on the intake
valves. Two printer cleanings after that and the several-week old
total clog of two nozzles was fixed.

Entlich's manual says you should not soak the whole print head
because you can short the electronics.

It is most probably clogged nozzles

boil some water;

fold a paper towell onto a saucer so it forms a 3 or 4 inch square

pour only enugh boiling water onto it to thoughroghly soak it.

Stand the print-head nozzle side down on the paper towell pad

wait a few minutes, then repeat with fresh pad and boiling water.

If that doesn't work do the same thing with paper towell and Windex
(Windowline in UK).

let it sit on the windex pad for a half hour.

If that doesn't work, youve got a candidate for the trash-bin.

Get one of these small $30 ultrasound cleaners used to clean dentures.
Fill with water (to the mark) and add a teaspoon of household ammonia.
Turn it on, immerse the head in the cavitating solution and wait a few
minutes. Without the benefit of the ultrasound unit, it is very hard
to drive cleaning solutins into these microscopic orifices. You
should see immediate results as the cleaning liquid blackens. Not a
bad investment if you have a printer (like the HP) that has removable
head/cartridge units.

Sounds like a fine idea. Anyone tried this on Canon cartridges?

Good suggestion. A light duty ultrasonic cleaner, such as used for
dentures, should work well for inkjet cartridges. Rather than using
ammonia you might try Kodak Photo Flo added to water. It's a wetting
agent and will increase penetration. Another one (and this might sound
strange) is Pine Sol.

Wetting agents, BTW, make water drops not stick to glass in the
dishwasher, so shaking out the cartridge after cleaning should leave it
relatively dry.

I used to use (back in my working days) a Koh-i-noor Ultrasonic Pen
Cleaner to clean fountain pens totally dried out, and clogged with India
waterproof ink. The ink wouldn't be dissolved, but would be softened
enough for me to take the pens apart for a thorough scrubbing.
Incidentally, don't try this at home. My pens were highly modified for
use with India. As I said, they had to be taken apart for final
cleaning. If you don't know how to do this, you could easily ruin your
pen.

I can't comment specifically on HP printheads clogging, as all my
experience has been with Epson printers clogging up; I've owned
several Epsons starting with the Stylus 400 Color and currently a
Stylus Photo 1270 and Photo 820. What I have found, consistently over
the past few years, is that my home photo printer NEVER clogs, and my
office photo printer is always clogged, to the point of being unusable
most of the time. The difference is in the environment. My home
printer is in a cool (50-65 degreesF) humid basement computer room,
and my office printer is in a warm, sometimes hot (72-90F),
low-humidity office. My home printer is almost always left turned on
and ready to go. Sometimes I don't print for weeks, and it still is
not clogged. My office printer is guaranteed to be clogged and
unusable on a Monday morning if left on over the weekend and always in
the hot summer months...

To resolve a cloogging problem on my office printer, the strategy I've
found works best is to run one cleaning cycle (that almost never works
right away)and then let it sit for an hour or more. Then run another
cleaning cycle, and let it set again for at least an hour or
preferably more. If that still doesn't work, run a third cleaning
cycle and let it set over night. An outrageous solution, yes, but this
has always resolved my toughest Epson printer clogging problems.
YMMV...

I have owned several Epson printers, and base on my very own experience I
had all of them running for years without any problem. But 2 inkjet
printers and 1 laser printer went dead after I moved them to my kids' system
(just another corner of the same long desk) and they all dead within 2
months.

I don't know what they did to the laser printer, but 2 inkjet they kept
printing 30-40+ pages without ink and they killed the printer. Now their
system hooked to a Multi-Function laser printer (already refilled toner
twice in 1 year, and drum life has 4% left) and I have 1 HP Photosmart 7350
(for my kids to abuse) and 1 Epson Photo 900 (to print CD/DVD label)
 
LOL!!!! Da putz haz a crappy Epson! LOL!!!!
