I have a Mac running Sequoia. Purchased my printer back in late March. Was working great until about a month ago when it started with the following: Issue description: prints solid blue pages intermittently even after confirmed-clean fixing assembly, faded/washed-out black text, "Could not perform adjustment" error on both gradation and color mismatch correction.
I have been using non-OEM cartridges, the same ones, since day one and never had a problem.This is affecting two different color stations in two different ways at the same time, cyan is overprinting and black is under-printing. That points to a shared component failure, not two independent cartridge defects. Customer service insists it’s a cartridge problem. Has anyone else had this issue?
