If the printer displayed a 099 FORMS JAM message while an operator was performing a Park operation,
advise the operator that the forms perforation must be torn off at the tear bar before confirming the Park
operation. The error occurs when the printer backs up the forms, but does not detect that the paper is back
on the tractor. The printer stops and displays "099 FORMS JAM".
2. Load forms into one of the push tractors. The top of the forms should be near the square drive shaft of the
tractor. Do not push the forms into the printer. This would block the paper presence sensor.
3. Press the Load key. The first form moves into the print area.
Note: If the forms move into the print area, but the top of the forms move past the printhead, and the "001
END OF FORMS" message returns to the display, perform T&D07 The paper presence sensor in that
forms path did not sense the forms.
4. If it appears you have paper loaded into a path, press the Path key. If the Path message changes to a
different path, perform T&D07 The paper presence sensor in that path does not recognize that forms are
present.
5. If your printer displays a "099 FORMS JAM" message when a paper load is attempted using the Load key or
under host command, you may have paper already in one of these paths:
v Front
v Rear
Remove the paper; look for debris or chad.
6.
a. Remove all paper debris from the rear path sensor area.
b. Perform T&D07 to reset the path sensor threshold level. This should remove the 099 FORMS JAM
message.
Notes:
1) If the printer is using a rear and a front path, repeat step 2 and step 3 at the beginning of this service
check.
