My printer keeps printing greenish and blue/yellow

Many aftermarket companies have inferior parts in their ink cartridges. Stay with the genuine cartridge for yours. To save money refill your own. They can be refilled at a low cost and the cartrige will reload about 7 to 9 times before it no longer any good to use any more

I would guess that the printhead is bad. Google cleaning printheads or get a new one. Sometimes , not always you can clean the printhead instead of replacing. (take out and clean by hand)

You need to make sure you are not using the photo magenta, your printer doesn't use photo magenta and it leaves the prints green. You need also to run the nozzle check print by holding the resume button until the green light flashes twice, and see if all colors are printed. If not you need a new printhead, the part number is on the side.

You'll need a new printhead, once they plug that bad nothing gets them clean again. Make sure the tape is off the top of the cartridge as well

I called Canon. I also had green 1 flash and amber 1flash everytime I turned on the printer. That right there indicates an elecrical problem. The flashes mean it needs serviced and with it not printing now means it's not wirth fixing, out of warranty. Canon did offer a code for reduced price new or referbished print from them.

Sounds like the print head is no good. This happens. Here's a link to a site that sells them reasonably.

Canon i850, i950, S600
Start with the printer OFF
1. Hold down RESUME and then hold down POWER
2. release RESUME
3. press RESUME twice, then release POWER
4. Let green light blink until printer is done futzing
Select function with RESUME press POWER to execute:
presses - light color - function
Number of presses - light color - function
0 presses - green - Test print (or exit service mode on i960)
1 press - orange - EEPROM info print (plus grid nozzle diagnostic on i960)
2 presses - green - EEPROM initialize
3 presses - orange - Reset waste ink counter


If I could be of furtheme know. If this helps or solves the issue, please rate it.
Thanks, Joe

Your problem is the print head. You can buy one from Canon for about $95, or find them new from dealers on Ebay for $60 to $70. For a less expensive fix, try to remove the print head and clean it. (You don't need any tools, just remove the ink tanks and pull the print head forward and out. Over time, the receivers tend to get dry & crusted ink on them. Note that the inks used are fast drying inks to keep your pictures, etc. from smudging after you print them. Try not to use solvent. I use q-tips and hot water, then dry using another q-tip. If this does not work, there are commercial cleaning kits available for about $10. Short of that, your choice is to replace the print head or the printer itself. My i960 prints such good quality color prints and normal color printing, that I would fix it rather than replace the printer. I hope the easy cleaning does it for you!

Yep same as above. Black prints very light gray after 5 years of good printing. Tried every test, replaced black cartridges with different brands. Just wondering if somehow you can clean the heads. I'm convinced the black head is almost totally clogged. Does anyone know how to remove the printer heas to do this?

I had this problem. If I tried to print a black& white photo on to glossy paper, it would only print green. When I tried on to plain paper using the 'fast' option, it printed in black. The reason for this is, on plain paper it uses the black cartridge, but output to glossy photo paper using the 'high' option, uses the mix of colours in your colour cartridge. If one or more of your colours has run out, you will get a print with the ink left in the cartridge. Replace the cartridge or refill it & your problem is solved.
