Re: black has stopped altogether

He says he replaced the cartridge twice. Possibly (most likely if it is an iP90 since after-market versions are rare) these WERE the OEM Canon cartridges! Therefore, the head assembly (a separate component, that holds the iP90 cartridges) is obviously the problem. Do this: I have written this for the Canon iP90. Generally, this will work for any printer that has print heads that are SEPARATE from ink cartridges. For example, older B/W BJ2 family Canon/Apple StyleWriter printers have ink cartridges that INCORPORATE the print head into the cartridge -so this will NOT work on them! (although I once succeeded in cleaning the heads, it was VERY messy and took several days, then required another trick thereafter). Also be aware that this is for B/W or Color printers that use water vehicle (water based) inks only (most are water-based, but some printer inks are alcohol, oil or acetone based). The appropriate vehicle/solvent must be used, and the WRONG solvent can damage heads! (for example, using water, alcohol or acetone for cleaning oil based ink cartridges can be disastrous). RESEARCH your ink "base" first, if you do not know what it is! iP90 Head Cleaning by DanaSaur: 1 These ink cartridges are grey. Remove both cartridges. 2 Now remove the head assembly that held the cartridges (black, with 3 small round seals and one large seal) (consult manual, in NEW setup sections, if still uncertain how). DO NOT TOUCH ANY PART OF THE SMALL WHITE PAD BENEATH THE ASSEMBLY. 3 Now take this whole assembly ONLY, (it is 4.5cmx5cm, 1.5inx2.0in) and drop it into a small container of warm water. DEFINE WARM: Think of a range between a "baby bottle" (slightly above body temp) up to any temp that does NOT cause pain/discomfort to the underside of your wrist!) Let it soak 30 minutes. 4 Take a NEW, CLEAN, SOFT toothbrush, dip it in warm water, and GENTLY clean the small components on the white pad below, AND the 4 seals inside the head assembly. 5 Rinse everything (even toothbrush) in warm water, under a faucet, until all items are clean (no color appears in water). 6 Repeat steps 3, 4 and 5 above (but can use the same toothbrush) This time though, leave assembly in water 2-3 hours, keeping it warm (replace water every 20 minutes or so). 7 Rinse everything again, as in 5 above, gently tap off excess water (DO NOT TAP WHITE PAD FLAT AGAINST ANYTHING -ONLY CORNERS) 8 Set assembly white side down, yet tilted on a corner with a pen or clean 0.5-1cm object, on a smooth, clean surface in a closet (or other isolated environment, to avoid dust/lint etc). 9 Set a small piece of tissue wadded up and soaked with water, in the same closet (but not too close to head assembly). This will be your "advanced, high-tech, moisture level gauge" :) 9. Allow the tissue to COMPLETELY DRY... even to its core! When this has happened (may take several hours -or day in colder weather) the head assembly is dry enough to re-install in the printer. 10 Install cartridges (may be best for you to buy new ones, sorry). Let them gravity flow with natural capillary attraction for a few hours (or allow a day if room is cool/cold). Always keep printer lid CLOSED to avoid drying out ink/clogging heads or capturing dust/lint from atmosphere. 11 run head cleaning process as many times as it takes to re-saturate heads with ink. 12. Now, after doing all these steps faithfully, if printer has not started working, you let the heads dry out way too long, or contaminated them with touch (skin oil) or the wrong solvents. You will need to BUY a new head assembly. Bend over bud, this is what gets Canon accountants ****! This is why they offer cheap printers -to extort obscene amounts of money when you need parts :)

Re: black has stopped altogether

You need to wait for about a day so the new ink can flow down to the print head and then do a deep cleaning and alignment. This should fix your problem

Printer has stopped printing in black

Remove the print head and cartridges.
Take 1 ounce ammonia to 7 ounces of hot tap water ,mix in bowl and let the head set in it for 30 minutes.
Ink ports in the solution.
Thoroughly dry the head and re-insert.
Do a deep clean and try again.
If that does not work remove head and spray some WD40 on the head eject nozzles.(head upside down)
Be careful not to get the WD on any rubber part.

Printer has worked perfectly since purchased, suddenly started printing only the black portions of a photo. Did a nozzle check which confirmed only black cartridge functioning. Deep cleaned all heads....

The print head is still probably still partially blocked. Cleaning/deep cleaning tries to clear the head by flushing ink through, doesn't always work but does use up your ink.

You can get print head cleaning kits, PC shops,ebay etc. Try one of those.

Here's a really useful ebay url. with some youtube links, if you run the second video down you should get a pretty good idea.

Here's a direct link :-

You don't have to buy this one, there may be cheaper, have a shop around.

Nothing is printing. It looks like there is no

Hi, To ensure this is only an issue with the black, I recommend printing off a nozzle check. This will show you if this problem is effecting any of the other colours.
To print a nozzle please refer to chapter 12 page 115 of the manual,

If colours are missing I recommend cleaning the print head. You have two options for cleaning the print head a normal clean and a deep clean, start by doing a normal clean if required try doing a deep clean.
You can download the manual here:

Test page prints fine, but nothing else does

You need a new printhead, QY6-0049-000 around $40.00. Your printhead has worn out or plugged nozzles and cleaning won't help.

Canon iP90 stopped printing in BLACK

hi... it might be that you need some time to let the ink absorb into the pads in the print heads ... this can take between a few hours and a day... Must be frustrating to deep clean three times and just seem that you are wasting ink cartridges, my "solution" would be to give it time or possibly clean the print heads manually.. hope it will solve it out..

thank u!!
