We've got a 3115CN with a problem that has recently developed.
Faxes are being sent with a vertical "shift". About 3" from the left of the page, there is a 1" blur, and shift down 1/8", causing text in that 1" region to be difficult to read.
It happens when sending faxes on both the flatbed and ADF, same spot.
The problem does not occur when scanning.
I'm out of ideas... any suggestions?
