Print Head Skew
1.
Loosen mounting screws.
2.
Pivot the print head around the shoulder screw until the skew marks on the
printout are parallel to the top edge of the paper.
3.
Tighten the screws.
Paper Feed Magnet Adjustment
1.
Remove the lower frame.
2.
Rotate gear no. 11 so the end of the magnet armature is away from the step.
3.
Hold the armature in the closed (coil active) position and rotate the magnet
counterclockwise so the end of the magnet armature contacts the outside of
the cam groove.
Note: If the gear has radial play, move the magnet until the play has been
taken up in the downward direction.
4.
Adjust the magnet as follows:
a.
Plastic armature: so there is 0.6 + 0.1 mm -0.07 mm (.024 + .004 in
-.003) between the armature and the pole piece.
b.
Steel armature: so there is 1.0
±
0.1 mm (039
±
.004 in) between the
armature and the pole piece.
5.
Push the magnet up and to the right in the direction of the plane of the
magnet armature and tighten the mounting screw.
Fuser Drive Gear Adjustment
1.
Loosen gear no. 1 mounting screw.
2.
Slide the gear all the way up.
3.
Tighten the gear no. 1 mounting screw friction tight.
4.
Move the gear no. 1 mounting screw down .35 mm (.014) and tighten the
screw.
Fuser Alignment Adjustment
If the fuser is misaligned, the trailing edge of the paper might move slightly when
released by the paper feed rollers. Use the Print Test as a quick check. If the
vertical lines are bent toward the left near the bottom of the paper, the fuser needs
to be rotated counterclockwise.
Adjust the fuser position so it is square with the paper path:
1.
Loosen the four fuser mounting screws.
2.
Move the fuser no more than 1 mm as noted above.
3.
Tighten the mounting screws. Be sure to maintain correct gear mesh.
