Toner Cartridge Holder Assembly
The Toner Cartridge Holder is responsible for transporting toner from the four Toner 
Cartridges to the Developer Assemblies. The following figure shows the location of 
each major component.
Note
When servicing components of the Toner Cartridge Holders, CRUM Reader, and 
cartridge sensors, avoid disconnecting the Auger Tubes from the Developer 
Frame Assembly. All repairs, excluding replacement of the holder itself and 
removal of the Developer Frame Assembly, are possible with the Auger Tubes 
attached. Once the covers are removed, re-install the Toner Cartridges to help 
avoid toner spills.
