Below is the scan. From my perspective the light magenta position vertical line is not good, the others look good. All of the staircase lines good to me. I'd appreciate your comments to see if I'm reading these correctly.
I have also done these things:
1) I have the the print head cleaning kit, and have gone through each ink position flush out.
2) I ran numerous nozzle check/head cleaning cycles. I can never get the printer to clean entirely, it always ends the cycle with a message that I should try a manual cleaning.
3) I have cleaned off the wiper blade, capping station and bottom of nozzle head per your video instructions. The wiper blade had a lot of caked on ink which is now clean, and since then have run a multitude of cleaning cycles and two runs of flushes with the print head cleaning kit. I have also flushed out the light magenta position a few more times since that appears to me as the problem child.
Thanks for the printer information. I typically print on weekends, sometimes more frequently. So the R3000 is not in your top picks?
Thanks again for your help!
