D-roll Assembly Removal
1. Unplug the power cord.
2. Remove the paper tray.
Note: The following 3 steps are not necessary, but may make it
easier to see the parts.
3. Remove the print cartridge.
4. Remove the fuser input guide.
5. Remove the transfer roll housing assembly.
6. Move your finger down off the end of the shaft to the latch
located above the flat part of the D-roll.
7. Push the latch down (away from the shaft) and slide the D-roll to
the left, off the shaft.
Note: There is no positive detent when replacing the D-roll. Make
certain the roll is in place by pulling toward the left without pushing
the latch.
Note: Later machines do not have a latch. Remove the D-roll by
pulling it firmly to the left. The D-roll without a latch is intended to be
installed only once; if it is removed for any reason it should be
replaced with a new one. The new D-roll may take considerable
force to install.
