I want to install piezoflush on all the channels of my 4900.
I launched 3 initial fill charge through the adjustment program. All carts ink level went down on the LCD display and the maintenance tank is indicating nearly full.
Since all nozzle checks still print full color instead of piezoflush, I checked the carts. They are all full! The maintenance tank is empty and not nearly full!
So it seems that the printer execute the cycles dictated by the software but without any ink going through the line. Is it a pump problem? How can I check for it?
When I make purge prints using quad rip, it prints but this is so slow to print 20 to 30 A4 for each channel.
Thank you in advance for advise.
