Service Parts Disassembly 8-81
Developer Assembly (PL7.1.17~20)
Since all four Developer Assemblies are removed in the same manner, use this 
procedure for any of the four colors.
Note
Toner will spill from the rear of the Developer Frame Assembly. Keep the 
assembly vertical to reduce the amount of Toner spillage. Prepare a location to 
replace the Developer Assemblies by covering a flat surface with paper or other 
material to capture Toner spilled during the replacement procedure. Following 
the repair, use an approved Type
 II Toner Vacuum to clean spilled toner from 
within the printer and around the work area.
