Thanks to both of you for responding. I'll go back thru older threads and see what I can find.
In the meantime I tried printing a "magenta" page but got a yellow square instead. Does that suggest the wrong signal is getting to the printer?
Newbie here... my Epson C86 quit printing the magenta colour recently. I bought a new cartridge but it still isn't printing. I've run the nozzle check, cleaning etc but don't know how to do anything more serious.
Suggestions please!
