The problem
I'm printing a double-sided brochure and the back appears offset from the front by a few millimeters. I've checked the file and it seems aligned. What could be causing this?
Cause and analysis
The offset varies between sheets and the file is correctly aligned: the problem likely lies in the paper feed mechanism or the physical alignment of the printer during the double-sided cycle.
The printer may lack a true automatic double-sided mode, or this feature is disabled: the operator may be manually flipping sheets between the first and second pass, introducing small positioning errors.
Wear or misalignment in the paper feed rollers could cause variability in advancement between passes, especially if the printer is older or under intensive use.
Solution proposed by GPX
A possible cause is variability in the sheet loading and feed cycle during the double-sided pass, related to the printer's specific mechanism (manual or automatic) or its maintenance condition.
