Paper Out Adjustment

Paper Out Adjustment

This procedure tests and sets the distance from the page perforation at which
a LOAD PAPER fault message is triggered. This adjustment prevents printing
on the platen when the printer runs out of paper. The measurement units are

distance of 1 or 2 dot rows above the perforation is acceptable; 5 to 7
dot rows above or any dot rows below indicates adjustment is
required. Also, although it is not required, it is advisable to test the
paper out triggering distance with 6-part paper, in order to verify
correct printing with multi-part forms.
