Xerox Phaser 6000 Service Manual

2-10 Xerox Internal Use Only Phaser 6000/6010 and WC 6015 MFP
Theory of Operation
Only the portions of the drum surface where the negative charge has decreased
below that of the magnet roller (electrostatic latent image) attract the toner to
form an image on the drum.
Once the toner is deposited on the drum, the potential and the toner-attracting
force of the corresponding portion decreases because the increase of negative
charge lowers the potential at that portion.
Primary Transfer
In the primary transfer process, the toner images formed on the drums are
transferred onto the transfer belt via the 1st BTR (first bias transfer roller). The four
color separation images are transferred from the drums onto the transfer belt in
the order of Y, M, C, and K.
The 1st BTR is a metal roller, to which the positive voltage from the HVPS is
applied. The 1st BTR positively charges the backside of the transfer belt with the
voltage generated by the contact resistance with the transfer belt.
The toner images on the drums are transferred to the transfer belt due to the
attracting force generated between the negative polarity of the toner image and
the positive polarity on the transfer belt.
