As only the black cartridge was failing to print I just cleaned the prong that engages with it.
After the printer 'charged' all the cartridges it indicated the cyan needed replacing. Having done this the nozzle check shows a failure of both black and cyan!
Where do I go from here?
I have now followed your instructions to the letter. The printer now functions on all colours except black.
2 years 10 months
For your information
:I did not follow your last advice but decided to try to unblock the black nozzle with a syringe and flexible tubing,which extracted 2 ml ink. Then I repeated the cleaning cycle, but to no avail
.Admitting defeat, decided to return the printer to Staples with a test page for 'evidence'. I then noticed that the new black cartridge registered only half full, so I replaced it again and ran another nozzle check. Two nozzle cleaning cycles later restored the printer to full functionality.
So I thank you again as your initial advice encouraged me to explore other options!
