Recently acquired a GR3770 and SC7700 and having a small problem with a faint line in the center of my prints with the black drum.
After cleaning the thermal head, which solved some of my problems and I came to realize the problem was in the drum.. there is a small crack on the black pad in the center of the drum under the master.
Has anyone else encountered this? or know how to fix it?
The line is minimal but very annoying.. see images below.
Many thanks in advance.
