I just acquired a used R2880 I’m planning to use for matte prints so I don’t have to switch all the time on my R3000. I knew when getting it that some of the channels were blocked:
VLM:many segments missing
LK: one segment missing
PK: 2 segments missing
VM: 16 segments missing
Y: 5 segments missing
the missing segments are the same from nozzle check to nozzle check.
Other colours are OK.
What concerns me is that I see cyan being deposited heavily onto the wiper and dripping all over lever system for the wiper. When I got the printer, the capping station and wiper was a mess. Ink was caked hard on the wiper and it took many scrubbings with a Q-tip soaked on piezoflush before I got it clean.
I will forward more information as I do more checks and cleanings. I’m currently concerned about the Cyan dripping onto the wiper mechanism.
