Problem with the RED Color not printing, check & change cartridges, Test print so many times problem Remains. Please Help.....


It sounds like your print head is clogged.

Try this on the cartridge.

01. Hot, but not boiling water.

02. Hot, but not boiling 50% - 50% mixture of Ammonia & water.

01 + 02: Hold Printhead - Only - in hot water or mixture for 12 - 15 seconds. Using a paper towel, firmly hold Printhead vertically onto paper towel as to where ink will "Wick" into paper towel. This may be done several times.

For very stubborn colgs, Printhead may be soaked overnight.

* Be very careful of your Printhead - even "Wiping" Printhead with paper towel can cause damage to Printhead - it doesn't take much.

03. Using a cotton Q-Tip & Isopropyl Alcohol [99% is best - 91% would work - if nothing else is avaliable, 87%], GENTLY rub the Printhead with Alcohol - this may be tried several times.

Problem with printhead please consult user guide


Use the printer's utility program to self-clean the printer. This process may need to be repeated as many as 5 to 10 times. Often this will resolve the problem.

Turn the printer off, preferably overnight, if the self-cleaning utility has not worked. The ink may need to soften before the self-cleaning utility will be successful. Turn the printer on and try the self-cleaning utility again several times.


Determine from the owner's manual where the print head is located. Epson printers, for example, are usually in the printer. Many other brands place the print head in the cartridge.


Remove the cartridge. For models where the print head is in the printer, drop seven to 10 drops of isopropyl alcohol (rubbing alcohol) down the ink receptacle area. This is the hole where the ink flows into the head from the cartridge. Run a few self-cleaning utilities. If necessary, allow to sit a few hours or overnight and repeat the self-cleaning utility.


Soak the cartridge print head in hot water if the print head is in the cartridge. Allow to soak overnight. Dry the print head area with a paper towel. Repeat the self-cleaning utility.


Place the cartridge print head in isopropyl alcohol if the hot water soak did not unclog the print head. Leave the print head covered in alcohol overnight. Use a damp paper towel to wipe off the print head area. Dry carefully. Try the self-cleaning utility again.


Purchase a new cartridge if the alcohol soak did not unclog the print head in the cartridge. This will provide new print heads that won't be clogged. Contact a service technician for repair of print heads in the printer if the alcohol did not unclog the print head.

Kodak esp-3 printer. the classic problem of clogged printhead. is there ANYTHING (notice the capitalization here) that I can do to clean it before I junk it??? please don't tell me to send the printhead...


This frustration is one of the downsides of having Epson, who almost insists on keeping ink tanks separate form printheads, unlike HP that keeps printheads build into the same housing, so you always have clean printheads.
Alas, your problem. needs some alcohol.
Seriously, get some alcohol, best would be to be a 50-50 mix with water for theoretically best results... but Vodka will do just fine. Take out the ink cartridges and pour some alcohol onto the spots where the nozzles meet the cartridges. The alcohol should gnaw through the dry paint in an hour. Also, you can apply some alcohol on a cloth and rub the bottom side of the printhead and rub the surface so the alcohol can work from top and bottom sides to get a more thorough job of cleaning up. I used to use a desoldering vacuum pump to force the process a bit and it worked just fine for HP printheads. I know that theoretically you should not touch the face of the printhead because you could "damage it" but from my experience it seems that it's just a marketing trick to get people not to restore old printheads and to buy new ones.
So, before you buy a new printhead and add a few kilos of CO2 on your carbon footprint, try the alcohol cleanup at least two times, just to be on the safe side that there's nothing else to do. Then, as a final act of desperation, get a mild nail polish remover and do the cleanup again, from both sides. That ought to do it :)

I suspect that the black printer head is clogged up, is that seomething that I can repair myself?


Hello
Yes you can repair by trying the following steps:-
Remove the cartridge. For models where the print head is in the printer, drop seven to 10 drops of isopropyl alcohol (rubbing alcohol) down the ink receptacle area. This is the hole where the ink flows into the head from the cartridge. Run a few self-cleaning utilities. If necessary, allow to sit a few hours or overnight and repeat the self-cleaning utility.
Soak the cartridge print head in hot water if the print head is in the cartridge. Allow to soak overnight. Dry the print head area with a paper towel. Repeat the self-cleaning utility.
Place the cartridge print head in isopropyl alcohol if the hot water soak did not unclog the print head. Leave the print head covered in alcohol overnight. Use a damp paper towel to wipe off the print head area. Dry carefully. Try the self-cleaning utility again.
Hope it helps, if so do rate the solution
good luck

My printer won't print anything - only blank pages. However, both ink cartridges have ink. Please help!


If the self-cleaning cycle does not solve the problem, try turning the printer off overnight to allow the ink to soften. Turn the printer on the next day and try printing a test pattern to see whether the problem has either disappeared or become less noticeable. This ink-saving procedure can work effectively because sometimes the dried ink on the print head needs time to soften before the printer head can be cleaned completely. Try running the self-cleaning utility again one or more times.
Steps for Manually Cleaning the Printer Head

If the overnight cleaning still does not work, there may be a layer of thick ink that is blocking the holes of the printer's head. The next option is to manually clean the printer head. Follow these steps:

* Determine from the owner's manual where the print head is located.
* Remove the ink cartridge from your printer and then dip a cotton swab in hot water or isopropyl alcohol and rub it against the print head. This should loosen any crusted ink. NOTE: Be careful, especially if you use isopropyl alcohol to clean your print heads: Some printers use rubber gaskets, and if you get isopropyl alcohol on the gaskets it could dry them out.
* For models where the print head is in the printer, drop 7 to 10 drops of isopropyl alcohol (91% denatured isopropyl alcohol - not 'rubbing' alcohol) down the ink receptacle area where the ink actually flows from the cartridge into the head. Run a few self-cleaning utilities. If possible, allow the printer to sit a few hours or overnight and repeat the self-cleaning utility.
* If the print head is in the cartridge, soak the cartridge print head in hot water. Allow it to soak overnight. Dry the print head area with a paper towel. Repeat the self-cleaning utility.
* If the hot water soak did not unclog the print head, place the cartridge printer head in isopropyl alcohol and allow it to soak overnight. Use a damp paper towel to wipe off the print head area and dry carefully. Try the self-cleaning utility again.
* If the alcohol soak did not unclog the print head in the cartridge you may need to purchase a new cartridge. This will provide new print heads that won't be clogged. Contact a service technician for repair of print heads in the printer if the alcohol did not unclog the printer head.

How do i replace the printhead


The Print head is sitting in a cradle. So do not confuse the cradle with actual print head. The cradle is the one that slides left and right on the metallic rod. Do NOT try to remove the cradle.

Make sure to use genuine Canon ink cartidges.

1) Unplug the power to the printer. Remove the USB printer cable.
2) Lift open the top cover by depressing the round button on the right side of the printer; exposing the printer ink cartridges.
3)Lift the grey lever on top of the cartridges. This dis-engages the printhead electrical connections. Remove all the 4 ink cartridges from the printhead. From the cradle hold the printhead from the top and lift the printhead by tilting it toward you. Make sure not to touch the electrical contacts in the back printhead.
4) Take a small plastic bowl and fill it with 1/4 inch or less with Rubbing Alcohol(70% Isopropyl Alcohol). Dip the bottom of the printhead in the alcohol. Soak printhead in the alcohol and shake it lightly so the dried ink clogging the printhead can come loose. Us paper towels to soak excess alcohol from the bottom of the printhead. Make sure not to damage the printheads.
5) Pour some alcohol from the top of the each inlet of the ink cartridge seat and again soak up any excess alcohol with paper towel. Let the print head dry up little.
6) Put the printhead back in the cradle and insert back the ink cartridges in their right seat. Lower the grey lever back into its position so the electrical contacts are made on the printhead.
7) Plug the power and USB port.
8) Print a picture or diagram with color in draft mode. You might have to do this couple of times, so that the inks starts flowing from the ink cartridge through the print head. Then print the same in high quality. If the heads are unclogged your printer should work as new.

Just one bit of advice: you may wonder if you've got the position right because the grey lever may not seem to be able to engage - it will, but needs a fairly strong push to click into position again.

HP OfficeJet 9110 Printhead Problem


This is the official way of cleaning HP print heads. I just totally dissasembled my HP 80 print head, and found that on the inside of the print head there was a giant glob of ink that was between the inside of the print head and a metal mesh filter material. You need to remove this glob, can only be done by opening the cartridge. Good luck, tell me what happened.

MP830 Cyan Ink won't print


I have fixed the problem with my MP830 not printing black. It was the print head. I took the print head out and noticed that the black was clogged.

Apparently as the print head uses such fine jets to get the quality levels up, it seems to be quite common for the print head to become clogged.

There are many ways of unclogging the print head, allot of people I read about used alcohol type liquids to clean with, but I was able to get mine unclogged using warm water, a syringe and some good quality paper towel.

Its a tedious process, but you have to unclog all the dried out ink out of the print head. Some people suggested soaking the print head over-night in water or alcohol, but I was too impatient for this method.

There are two small screws which I undid, this allows the print head to come apart and give you better access to clean. using warm water in a syringe(large needle and body-the type used for re-filling cartridges) squirt water into the offending color hole. you should be able to see all the dried ink comming out.

The paper towel is used to bleed the water and ink through the printhead slots.

If anyone is interested in the method which worked for me, feel free to drop me an email and I can offer some more details, maybe would be easier with a few pics too.

I am outta time, kind of hard to explain in a few paragraphs.

My printer was 2 weeks out of warranty when I did this, there was no way I was going to pay a cent more for a new print head thats for sure.

Use this method at your own risk.

Print head cleaning/cleaner


I've had some success, if one hasn't been printing with the ink dry for awhile , through soaking the entire printhead in a bowl of alcohol. Soaked it for 1-2 days wiping it from time to time. Took awhile, but it worked. Might have to do it again soon. Bottle of rubbing alcohol 80 cents. New print head $38. Rather waste the bottle of alcohol :P

I have not had great success at all with my brother's canon. He ran it clogged for almost a year and I tried the above and it didn't work. I'd say the transistors in the print head probably overheated and it's shot so he bought a new one. Too bad Canon doesn't make it easier to buy new printheads.
