The symptom is mostly clearly seen in the attached image.
Black text prints double and out of alignment. In a test print, the PGBK sample prints with a bowed and mirrored effect. I've tried running a nozzle cleaning numerous times. I've removed all cartridges and cleaned the print head a couple times. I haven't been able to fix the problem. I've seen a few references to this symptom online, but the solutions weren't clear or they didn't work for me.
Have you seen this problem before? Do you know how to fix it? Is the fix steps I can do myself?
Thanks in advance.
