Fuser Assembly Thermoswitch Removal

Note

Six of the seven latches are accessed from the top

of the wire cover. These latches are beneath the

felt pad. The slot on the front left side of the wire

harness cover is the best place to begin removing

the cover.

1 Remove the Wire Harness Cover as shown in Figure 6-42a

(LaserJet 4) or Figure 6-42b and c (LaserJet 4 Plus).

2 Remove the (2) screws from the Thermoswitch connector (see

Figure 6-46, callout 1).

3 Release the thermoswitch latch from the paper sensor flag

side of the Fuser Assembly (behind the side cover). (See

Figure 6-46, callout 2).

Slide the Thermoswitch to the gear side of the fuser and

release it from the fuser frame (callout 3).
