[A]: Lower cover ( x 1)
[B]: Pressure roller cleaning unit ( x 2)
[C]: Release the pressure arms
• Use screw driver to lower the pressure arms on both ends of the pressure
roller ( 3.9.8) and remove the springs [D] (x 2) on both sides.
[E]: Pressure roller
NOTE:
1) The fusing lamps are fragile. Work carefully to avoid breaking them.
2) During assembly, handle the roller carefully to avoid scratching it on the
bracket.
3) Make sure the tabs and grooves of the lower cover are engaged
correctly before tightening the screw.
Spring Adjustment
Two holes [F] are provided on each pressure arm for the springs.
Normally the springs should be attached to the lower holes. Attaching the springs
to the upper holes exerts less pressure on the hot roller. Attach the springs to the
upper holes only for especially thin paper.
