I know it sounds stupid but do you have the old black cartridge, if you do put it back and see if it is printing even if the quality is poor and faded. If it is then possibly there is a contact bad, try swittching the black cartridge for one of the other colour ones, but put a colour in to the black space but don't put the black into one of the colour spaces. If the colour one is working in the black space then it's basically a dud cartridge and bring it back to where ever you got it from. Hope it works for you - Pat
printer working ok-did 50 colour photos ,6x4 when i made a mistake and pushed the print button when there was still about 1 inch of the previous photo still being printed.This print emerged with overprint of about 1".Thereafter the printer has refused to operate properly the next print being heavily discoloured.It then told me to replace the light magenta cartridge-this I did and the discolouration changed hew.It then told me to change the magenta and light cyan carts.-I did and discolouration changed again.It then told me to change the yellow and cyan=siscolouration now bright
red over coloured. I then successfully printed a letter in B&W proving that the black cartridge was still working.However as soon as I tried again to print a coloured photo it now tells me that the machine does not recognise the black cartridge and orders me to change it and until I do refuses to take any instructions telling me to install the black cartridge cprrectly.The black cartridge installed isout half full and has successfully printed copies and photos.I have carried out the suggested remedies by the machine and none were effectuve.How do it the infernal machine working again???
Printer doesn't identify the ink accurately all these are controlled by software only.So it is showing your black cartridge is empty but trace amount of ink actually remained,by this you are getting black and white prints correctly.After the consumption of that trace amount of ink it may print black text as a greenish-brown because printing taking place only by means of color cartridges.So if you observed blurred text or greenish-brown text, now you can replace your ink cartridges.
it is better to change the black cartige becaue there is the jam of the ink in black cartidge. or pick out the black cartidge and clean with soft paper in the place from where color is pour. then reinstall the cartidge. i hope it will ok. otherwise, change the cartidge. byee
try this. OK, Canon will hate me for posting this. 1. Remove ink cartridges 2. Remove print head 3. go to sink or tub (stainless steel, not plastic type), pick up a roll of paper towel on the way. 4. Fold several layers of paper towel and place on flat surface. 5. Run hot water until HOT! 6. Turn hot water back to a dribble. 7. Run the dribbling hot water through print head, be careful not to wet the gold contacts. 8.When water running through print head is clear, place print head on paper towel. 9. Repeat number 7 and 8 until no colour shows on paper towel. 10. Gently DAB print head (DO NOT WIPE) inside and out with dry paper towel until dry. 11. I normally replace print head after drying, but you may wish to let it air dry overnight. 12. Replace print head in printer and install cartridges 13. Start printing. I do this to all 4 of my Canon printers every 6 months or so. If any colour fails to print after this process it means your print head probably needs replacing.
Have you tried a new colour cartridge? This is a classic sign that the cartridge may be low on ink. When printing text, assuming you are printing black, it is likely that the black cart is doing most of the work so the gaps are insignificant. You could try printing text in several different colours. If the colour cartridge is low, you'll find that some colours may be ok but others may have gaps.
Is it a new cartridge? If the cartridge has been sitting a while it can get clogged. Try using a moist paper towel and gently wiping the cartridge where the ink comes out. You could also try running the Lexmark Solutions Center program and use the clean nozzles option to force it to squirt out some black ink.
