I have had the above mfd for some years and it has been an excellent machine for me. Two days ago I tried to print a letter but whilst it printed completely it was so blurred it was impossible to read it. Both colour and b & w were exactly the same. I had noticed some faintness over recent days and the blacks had a green tinge.
I had been on the website and downloaded some updates, don't know whether these would have affected it .The machine itself appears to be working fine.
I replaced both the PGI-5PK and CLI-8BK cartridges but there was no difference. So I then performed a clean followed by a nozzle check, but whilst the nozzle check printed all right the grid at the top wasn't complete and the colours were very faint.
I then uninstalled and reinstalled the printer, but there was no improvement. I then tried to carry out a further clean following the instructions in the manual, but discovered the "Home" button isn't working.
I would very much appreciate any help which the forum is able to give me. My OS is Windows 8.1
