Replacing The Photoreceptor Drum
145
CAUTION
In order to position the drum slot and the drum shaft pin, push 
the drum in all the way to the back and rotate it until you feel it 
drop in place. Failure to lock the drum in place properly may 
cause severe damage to the printer.
Never force the drum onto the shaft. If it feels as though the 
drum is not seating properly, remove the drum and inspect the 
shaft for any foreign material or burrs.
22. Remove the drum auxiliary rod from the drum shaft.
23. Install the nut and tighten it securely by hand on the drum shaft.
24. Install the lower inner cover and secure it with the two screws 
removed earlier.
25. Install the drum plate and tighten the thumbscrews. While 
installing the drum plate, place your thumb over the copper 
grounding clip and hold it in place. Otherwise the grounding clip 
can be bent, making no contact with the drum shaft.
26. After installing the drum plate, visually verify good electrical 
contact between the copper grounding clip and the end of the 
drum shaft.
Alternatively, measure the resistance. Connect one lead of an 
ohmmeter to the bracket on the drum plate, and touch the other 
lead to the edge of the drum. Normal resistance should be 0 
Ω
.

transport unit to the right.
