Xerox Phaser 6100 Service Manual page 31

1) Imaging Unit
The imaging unit creates the image using an electro-photo process. The imaging unit consists of the following:
An OPC Drum
Waste Toner Assembly
Charge Roller Assembly
2) Transfer Belt (ITB)
ITB stands for Image Transfer Belt. The image developed on the drum is transferred first to the transfer belt. This
is called the T1 transfer (Primary Image Transfer).
The printer uses a four pass process to place the image on the transfer belt.
The image is created on the drum and transferred to the transfer belt in the following order: first yellow (Y),
then magenta, then cyan, and finally black.
3) Transfer Roller
Once the transfer of the image from the drum to the belt is complete, the full image is transferred from the belt to
the transfer roller. The transfer roller then transfers the image to paper. This is called the T2 transfer (Secondary
Image Transfer).
4) Tray 1 or FCT (First Cassette Tray)
Tray 1 stores and feeds paper to the printer. A pick roller picks paper, controls drive, feeds paper, and removes
static electricity from the paper.
