be affected if the gears are too tight.
1. Remove the fuser cover.
2. Locate gear #2. It is the white adjustable gear-mounted to the
side frame below the fuser gear.
3. Rotate the adjustable gear in one direction to check for
backlash.
To adjust backlash:
1. Loosen the nut on the idler stud.
2. Move the idler stud downward in its slot.
3. Insert a 0.95 mm (.037 in.) feeler gage between the gear
shoulders from the front of the machine. You may need to use an
angled or very small feeler gauge.
4. With the nut snug but not tight, tap the idler upward until the
gage is snug between the gear shoulders.
5. Tighten the locking nut.
6. Check the clearance again; tightening may have altered the
adjustment. Be sure the fuser gear can be rotated slightly when
gear #2 is held still.
