Tear-Off Line; Service Check - InfoPrint 4247 Z03 Maintenance Information

Attention: Do not use T&D09 for this procedure. T&D09 only applies to the paper presence sensors.
When the printer displays a 002/020 FORMS JAMMED message, examine the tractor for damaged forms.
v If you do find damaged forms in the tractor, go to MAP 0190: Form feed problems to check the forms path.
- or -
v If you do not find damaged forms in the tractor:
1. Look for paper chad inside the tractor sensor. If you find chad:
a. Use a lint-free cloth to wipe the sensor. As a preventative measure, apply anti-static liquid (P/N 2200118)
to the sensor, using a lint-free cloth. Consider occasional treatment, if problem recurs.
b. If you find chad, and judge it to be excessive, advise the customer to:
v Frequently clean out the chad.
v Ask the forms supplier to reduce the chad.
2. With the printer turned on, look at the back of the tractor sensor. In a darkened room, you should be able to
see the red dot of the light emitting diode (LED). If the LED is not lighted, verify that the tractor is plugged
correctly into the electrical socket. If you determine the mechanical connection is adequate but the LED is not
lighted, replace the tractor assembly.
3. Verify the sensor can read the tractor holes in the forms.
a. Mount forms onto the tractor pins.
b. While holding the paper in place, advance the forms by hand cycling the upper feed roller.
c. Ensure the sensor is positioned so the LED light passes through the tractor holes.
d. If adjustment is indicated, loosen and retighten the sensor.
e. If adjusting the sensor does not correct the condition, replace the tractor assembly.
