There are two types of biases: DC positive bias - HP 4700n | Service Manual - Page 180
of developing bias: The developing bias is the DC negative bias that is generated to adhere toner to an electrostatic latent image formed on the photosensitive drum. This bias is generated for each color. The high-voltage power supply PCB applies the developing biases (DEV1, DEV2, DEV3, DEV4) to the - HP 4700n | Service Manual - Page 181
during continuous printing. ● Cleaning bias: This bias cleans the ETB by returning any toner remaining on the ETB surface to the photosensitive drum. The transfer rollers in the yellow and magenta cartridges (first and third colors) are applied with DC negative bias. The rollers in cyan and black - HP 4700n | Service Manual - Page 182

The latent images on the photosensitive drums are developed by toner and transferred onto paper in this order: Y (yellow), C (cyan), M (magenta), and K (black). 8.

system forms the latent electrostatic image on the photosensitive drum according to video signals sent from the formatter. The main components of each laser/scanner assembly are the laser driver, scanner motor, mirrors, and focusing lenses. Each color has its own laser/scanner assembly unit, which - HP 4700n | Service Manual - Page 184
the laser beams on the photosensitive drum scan on the drum. 7. As the photosensitive drum rotates and the laser beams scan on the photosensitive drum, both at a constant speed, a latent image is formed on the drum. Laser control The laser control circuit allows the laser driver IC to turn the laser - HP 4700n | Service Manual - Page 185
to strike the laser beam at the correct position on the photosensitive drum. The DC controller divides the oscillation frequency of the oscillator (X1201) (/SCNACC1) or deceleration signal (/SCNDEC1) to the scanner motor driver based on the detected rotational speed.

Monitors the frequency comparator - HP 4700n | Service Manual - Page 187
Image formation system The image formation system is the central hub of the printer. It also forms the toner image on the media. The image formation system consists of four cartridges, the ETB, and the fuser, which are controlled by the DC controller.
