Hello!
Asking around while I wait to hear back from HP. I noticed a sudden, and significant color shift (grey went from green/yellow cast to pink). My first course of action was to replace the lm/lc printhead since it was already out of warranty. However when I ran a color calibration there was noticable banding in the LM/LC color blocks. Nothing unusual came up when I printed the standard test plots.
I've also run through the following: Force Drop detection - checked out, numbers weren't unusual Printhead cleaning - multiple times Cleaned printhead electrical connections Printhead replacement - 2x Encoder strip cleaning
I'm a little stumped at this point. Any suggestions on what this might be, or what else I should try?
