Drum Transfer 1: intermediate transfer roller 1). There are two IDT1's: one for yellow and magenta and one for cyan and black. IDT1 is conductive and receives a high positive charge from the HVPS. The negatively charged toner image on the drum 2-2 Phaser 6250 Color Laser Printer Service Manual - Xerox 6250N | Service Manual - Page 42
located on the Transfer Roller Assembly. This negative charge neutralizes and eliminates the charge on the print media resulting from the tertiary transfer. 10. Fixing: The finished toner image is unstable and easily smeared. To fix the image, the print media goes through the Fuser Assembly where it - Xerox 6250N | Service Manual - Page 43

system from obtaining a proper electrostatic image.

, cyan, and black), are generated and transferred to the transfer roller as specified in the Bias Control section. The CTD (ADC) sensor measuers the density of each patch. The printer adjusts the toner dispense time, which changes the quantity of toner to be dispensed. This calculation is made - Xerox 6250N | Service Manual - Page 47
and detects the reflected light from the transfer roller. For exact density measurement, the sensor output value (reflected light density) must be the specified value when no toner is put on the Transfer Roller. The reflected light density varies 2-8 Phaser 6250 Color Laser Printer Service Manual - Xerox 6250N | Service Manual - Page 48
reflected light density can vary greatly if the transfer roller has been replaced or the CTD (ADC) is made just before the patches for toner density control are generated. Light is emitted the printing. Color Registration Control The printer uses a quad system where drums and developers are used - Xerox 6250N | Service Manual - Page 49
