I am printing K7 on 9880 and 3800. There is a nozzle clog on magenta of 3850 so I print GO ink on magenta. Before installing K7 ink sets on 3800, I have install 9 piezoflush and make sure I got the same piezoflush red color without color staining on every channel. Then I install the K7 ink sets and power clean for several times.
Both printers share the same bottle of S1, S2, S3 inks. But I got a green color shift on S2 only on 3850. At fist, I thought I might have mixed up the S2 ink so I installed a new refill cartridge with the same bottle of S2 ink but the S2 is still green after several power cleaning. I also tried to switch the cartridge position between S2© and S7(Y). The new S2 on Y is still green and the S7 on C is fine. I have already cleaned the capping station/wiper blade/print head according to the instruction. I have seen slightly banding on C(S2) but all nozzle check are fine (I could not see GO on magenta however). Is it means that I would need to replace the damper? Thanks~
