Solution

If printed images are affected by banding in different colors across the sheet, execute [Adj. Quality] for automatic adjustment of the paper feed amount. There are two modes for [Adj. Quality]: [Auto] and [Manual] but normally execute [Auto]. Use [Manual] adjustment with highly transparent media or other paper for which [Auto(GenuinePpr)] or [Auto(Other-Paper)] cannot be used.
Automatic Banding Adjustment There are two modes of automatic adjustment to correct banding: [Auto(GenuinePpr)] and [Auto(OtherPaper)]. In either mode, the printer prints and reads a test pattern for automatic adjustment of the feed amount.
Use this mode with paper identified in the [Paper Reference Guide].
Use this mode with paper not in the [Paper Reference Guide], or if [Auto(GenuinePpr)] does not eliminate banding.

When Using Rolls:
An unused roll at least 254.0 mm (10.00 in) wide
When Using Sheets:
Auto(GenuinePpr) : One sheet of unused paper, A4/Letter size
