Yellow isnt working


Let's try a couple of things. First, have you tried a different yellow cartridge?
If you have, we can try cleaning the printhead. Remove the printhead and soak it overnight in a warm distilled water bath. This is the gentler alternative to the more aggressive head cleaning solutions. After the soaking overnight, blot the printhead being with a lint free cloth being careful not to brush the electronics. Reinsert the printhead and reinstall the ink cartridges. Try printing. This should clear the printhead clog. If the printhead is severely clogged, you may have to repeat the soak.
Let me know if this clears the problem.

Additional problem: Where do you find the print head on printer to clean as you suggested?


I have the MP610 model, which may very well be similar. I recently had to buy a new printhead because I did not use the printer often enough and no end of deep cleaning would clear the blockage on one of the ink jets. Not cheap, so if you could share the advice given on how to attempt to clean a printhead, I would be very grateful.

I did hear you could clear blockages by running hot water over it, but the engineer from Cannon said there was nothing I could do - but then he would would't he. I noticed he insisted he took my printhead back for refurbishing, so it can certainly be done, if you have the right solvents and know-how.

If it helps, you get to my printhead by lifting the two 'lids' as you do when you replace the ink cartridges. You take out the inks; use the lever and the printhead pops out. If you assembled the printer when it arrived, it is just a simple reverse of that procedure. The same inks can be replaced later; the engineer said there would not be an air-lock problem.

Let me know if that works. I can look more closely at my printer to be more specific if that would help.

Please advise on removed print head cleaning.

Have ink, but its not printing. the paper is doing the right thing ,but not putting ink on paper


Please make sure that the print head is not clogged. The ink can flow out easily from the print head. How do you know if there is no dry ink clogging the print head? Remove the cartridge and run the print head in a soft smooth paper, see if the inks was left in the paper proportionally. If no ink marks then its clogged.

flushing the print head of the cartridge directly from the tap water will help ....Open your printer cover, remove the cartridge..place the printhead directly on a tap water running slowly. This will help flush the dried ink that clogged in the printhead. Turn the print head over, bottom side up until you see the ink flowed out from the printhead, do this until you see the a smooth flow of ink..(better result if the water is warm).. tap water contains residual minerals that can clog also the printhead..so it is advisable to final flush the printhead with a distilled water (it has no impurities) and dry it with cloth..

The last thing to do and it will take you sometime is to soak the printhead portion of your cartridge in a mixture of ammonia and hot distilled water, (please make sure that the contact point of the cartridge to the printer is not soak).. Place the printhead on the hot water and leave it there for about 4 to 5 hours..move it on different location from time to time..After soaking, rinse it with distilled water and dry it with cloth...

After doing the instructions, return back the cartridge to the printer and do the printhead alignment..

Try printing a test page and see the outcome...


If you find this information very helpful, would you be kind to rate this solution. Thanks

I have a brother DCP-135c printer. the magenta ink not printing


The process to get to the print head will take you approx. 1 hour. Without being trained on it, there is a high failure rate upon completion.

The Scanner assembly needs to be taken off. Harness Cables for the Scanner need to be removed.The Upper Case Assembly needs to be taken off. Printhead casing and printhead tubing calbes need to be removed, printhead mainboard needs to be removed, and then you have access to the printhead.

Thanks

My Kodak 5500 all in one won't print in black ink


This is a common problem. Please follow the below mentioned steps:
  • Reseat the ink and the printhead on the printer.
  • On doing this, the printer will ask you to print a calibration sheet for which, it would display the instructions on the printer screen.
  • After printing the calibration sheet, press Menu button and got to the option Clean Printhead and hit ok.
  • Choose deep clean and hit ok.
If the issue persists, you need to get another printhead.
Kodak will not charge you for the printhead.

The printer is not recognising cyan ink cartidge CLI-BC even though it is full


Try doing a nozzle check to see which colors are getting through the printhead. If you are missing lines in the pattern or there is no ink color showing, you will have to do a head cleaning. Was your printer out of ink for any length of time? If so, it is a clogged printhead. some printers are designed in a way that will not allow you to print at all, if you are out of a color. They do this for a specific reason- If you were allowed to print in black and you were out of yellow and you did this for a month and then replaced the yellow, you would have a clogged printhead. Why? Because there is a reservoir in the print head and if you do not replace the ink, after a while, the ink in the reservoir will dry out and you will have a clogged printhead. The only way to fix this is to do a head cleaning (2-3-4, depending on how bad the clog is) and that uses a lot of ink. So, Epson does not allow you to print if one color is out, to save you the time and expense of having to do a head cleaning.

Did you remember to take the tape off the top of the cartridge? If so, run a few cleanings and do a nozzle check. If there is still no cyan, your print heads may be clogged

CANON MP830 all in one is sayin" the type of printhead is incorrectn Install the correct Printhead."


Hi follow the instructions as above...
ie Remove inks and print head...

But instead...
Whilst Canon print head is out...

Use cotton wool and alcohol and clean electrical contacts on back of print head and where they make contact inside printer.

Then install print head and inks and test.

If it does not work you may need to replace print head.
