Model 78xx Series.

Problem: Document handler is calibrated wrongly causing documents to be wrongly positioned on the page compared to original.

Solution: There is an automatic calibration routine in diagnostics>adjustments> dc608 but this is known to error and not run. There are a number of NVM values you can change manually;

715-510 – Vertical Registration Side 1

715-511 – Vertical Registration Side 2

711-140 – Lead Edge Side 1

715-515 - Lead Edge Side 2 (7845/55 only)

This only relates to DHDF and not platen glass.
