Fusing Assembly
1 Open the Diverter Assembly access door and remove the Duplex Unit if
installed.
C a u t i o n Use the upper levers to release the Fusing Assembly, NOT the lower levers.
The lower levers set the pressure rollers inside the Fusing Assembly for
envelope printing (down for single sheets, up for envelopes).
2 Release the Fusing Assembly by rotating the upper levers down (Figure
6-25, callout 1).
3 Remove the Fusing Assembly by lifting up on the finger handles (Figure
6-25, callout 2) while pulling outward.
To Reinstall:
1 Make sure that the Fuser Output sensor flag (Figure 6-25, callout 3) on the
upper left corner of the Fusing Assembly rotates freely.
2 Make sure that the lower levers are set down for single sheets. If having
trouble printing envelopes, move the levers up. Move the levers back down
when done.
