The Problem
During printing this defect appeared. Previously the job was printing correctly. From the photo can you understand what I can check before stopping production?
What Emerged from the Case
Is the job still to be printed or has it already entered production? yes
Cause and Analysis
The misregistration between colors varies in magnitude across different areas of the sheet and changes from print to print, consistent with mechanical misalignment of the paper transport system or printhead positioning (a possible cause is slippage of the transport belt or irregular wear of the rollers)
An accumulation of ink or dirt on the transport rollers or pressure rollers could reduce friction and cause intermittent paper slippage during passage, generating the observed misregistration
Solution Proposed by GPX
A possible cause is intermittent slippage of the transport belt or irregular wear of the drive rollers, generated by accumulation of ink, dirt or dry lubricant
