Remove the waste toner bottle (WTB

Unplug the green cable.

Remove the imaging kit
. Pull the unit out of the device and set on flat surface.

Unlock the DHDA

) by turning both blue levers; this disengages the 4 Imaging Units (developer unit and photoconductor).

Inspect the developer unit to make sure all levers are in the closed position and all contacts don’t have any damage.

Reinstall the imaging kit and plug in the green cable.

Insert the waste toner bottle then close Door A and Door B.
