Adjustment Procedures
Adjusting the End of Forms Distance
This procedure tests and sets the distance from the page perforation at which
a LOAD PAPER 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 Paper Out Dots printer test to verify that this parameter is set
correctly.
NOTE: Do this procedure only if a new paper detector switch assembly has
been installed, or if you are sure that the end of forms adjustment is
incorrect. A paper out triggering distance of 1 or 2 dot rows from
the perforation is acceptable; 5 to 7 dot rows off 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.
The procedure below describes how to run the Paper Out Dots printer test
and modify the paper out adjustment value.
1. Power on the printer.
2. Load paper and set the top of form. Make sure the forms thickness lever
is closed.
3. On cabinet models, open the cabinet front door.
4. On the sheet of paper just below the paper entrance slot, tear a four-inch
square on the left side, immediately below the perforation. (See
Figure 4–9.) This creates a hole that will trigger a PAPER EMPTY fault
message, but allows printing to the right of the hole (which would
normally be on the platen).
