You need to reorder R1 (Black drum) so you have one on hand when it fails and tells you to replace it.
The smudge may be that the drum has already failed prematurely
I keep getting a notification on there that says something like “reorder R1 but do not replace,” Can anyone tell me what I need to do to fix this?
Also, there have been grey smudges at the bottom of each print job that have not gone away. I tried to run blank paper through to try and get rid of it, but they still show up. Any suggestions on how to clean it?
