Hi,
I have possibly made an expensive mistake - buying second hand 11880. The seller wasn't exactly the user of it, so I have just asked him to print a nozzle check which came out with Cyan missing 10 lines and Magenta 6. I thought, fine, after a few cleaning cycles it should be fine.
I have done quite a few cleaning cycles, and there is no difference at all.
What is quite strange and maybe also the source of the problem - is that once the printer is switched on it, the pressure pumps are constantly working, with a few seconds gaps. Is this normal ?
After studying the field repair guide I found out that Cyan and Magenta are on the same part of the print head - is it possible there isn't enough pressure getting there or something to do with that ?
Can anybody confirm if the printer should be completely quiet once started up ?
Many thanks for any advice....
