ADJUSTMENT
1. Select PW sensor adjustment in the adjustment program.
2. Print the PW sensor adjustment check patterns, choose the pattern number 5mm
away from each edge, and enter it in the adjustment program.
During the printing of the PW adjustment pattern, do not open the
Printer cover. The PW sensor may be affected the light and the
sensor can not detect the edge of the paper.
If the adjustment pattern is not printed on the paper (especially
right side pattern on the pinted paper) even if the printer cover is
closed during the printing, check whether any foreign object or
small paper scrip is on the Paper guide front.
If these object is observed on the Paper guide front, remove it
completely. The PW snesor can not work correctly.
