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 dot rows.
You will use the dot row patterns printed by the Paperout Adj. test to verify
that this parameter is set correctly.
NOTE: Do this procedure only if a new paper detector switch assembly has
The procedure below describes how to run the Paperout Adj. test and modify
the paper out "Dots" value.
1. Open the printer cover.
2. On cabinet models, open the cabinet front door.
3. Load paper. Make sure the forms thickness lever is closed.
4. Power on the printer.
5. On the sheet of paper just below the paper entrance slot, cut or tear a four
inch square on the left side, immediately below the perforation. (See
Figure 16.) This creates a hole that will trigger a LOAD PAPER fault
message, but allows printing to the right of the hole (which would occur on
the platen in a true paper out condition).
6. Cut or tear a four inch square in the manner described above, on every
third sheet, until you have made 3 or 4 holes.

been installed, the controller board has been replaced, or if you are
sure the paper out adjustment is incorrect. A paper out triggering
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.
