• The fusing lamps are fragile. Work carefully to avoid breaking them.
• During assembly, handle the roller carefully to avoid scratching it on the bracket.
• 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.
