Hi I have a Lexmark Optra S 1255 mono laser printer left hand margin is affected by a saw tooth pattern where printing is missed. I shall be satisfied if you are able to tell me what to do that will fix the problem. I shall not be satisfied is you tell me it needs to be serviced or repaired by others. Hope that is fair. Richard
No changes to printer parts.
pattern is missing print
The pitch of the saw tooth pattern is about 6mm.
The drum is as you say green metallic, it has not been touched or exposed to light since the problem started. it is also 25mm dia (probably one inch).
the mark (lack of print) is very distinct. bottom edge perpendicular to the roller, top edge about 30 degrees to bottom edge.
if it was damage to the roller I should think it would be at a pitch of 507mm (circumference) not 6mm. Would you agree?
Anything you can suggest I can do to fix it?
The drum may be the problem but I see no logic given the pitch of the mark 6mm all down the page, and the circumference of the drum being 507mm.
A repeat roller pattern would be at 507mm pitch.
Please do pass to another expert.
