Media Feed Correction
Check & Adjustment
Adjust the paper feeding amount by the outer diameter size
of the drive roller and the paper sliding amount which
differ depending on the printer.
Feed A4 Matte Paper from the ASF and print out the
adjustment pattern using the Service Program. Check the
adjustment pattern and decide the standard value from the
result. In the case of the media other than A4 Matte Paper,
the feeding amount is corrected based on this standard
value.
If the adjustment is not executed, the paper
feeding accuracy lowers and printing troubles
such as banding or misalignment of the printing
position may occur.
