Phaser 6200 Color Laser Printer - Service Manual
Summary of the Printing Process
The Phaser 6200 Color Laser Printer is a ‘full-color laser printer’, applying the
principals of an electrophotgraphic system. The system, comprising a drum and
developing unit for each color (yellow, magenta, cyan and black (YMCK) ), places
the toner image of each color onto print media producing full-color prints through
three intermediate transfer units (IDT1: 2, IDT2: 1). The following procedures are
summarized. The printing process is composed of the following steps, see the
illustration on the following page as a reference:
1. Charging:
The drum surface rotates at a constant speed while being uniformly
charged with negative electricity. This process is performed simultaneously for
YMCK.
2. Exposure:
The charged drum surface is scanned by laser beams to form an
invisible electrostatic latent image on the drum surface. This process is performed
simultaneously for YMCK.
3. Development:
Toner is electrostatically attached to the invisible latent image on
the drum surface to form the visible image on the drum. This process is performed
simultaneously for YMCK.
4. Primary Transfer (drum --> IDT 1):
The toner image formed on the individual
drum surface is transferred onto the surface of the IDT1 (intermediate Drum Transfer
1: intermediate transfer roll 1). There are two IDT1’s: one for yellow and magenta
and one for cyan and black.
5. Secondary Transfer (IDT 1 --> IDT 2):
The toner image formed on both IDT 1
surfaces are then transferred onto the surface of IDT 2 to create a 4-color toner
complete image.
6. Cleaning:
Toner remaining on both IDT 1’s after the image transfer to IDT 2 is
temporarily stored in the IDT 1 cleaner.
7. Tertiary Transfer:
The finished toner image on IDT 2 is transferred onto the
print media using the voltage supplied by the transfer roller.
8. Cleaning:
Toner remaining on IDT 2 after transfer is temporarily stored in the
IDT 2 cleaner.
9. Static Elimination:
Negative DC voltage is applied to the back side of the print
media by the Detack Saw, located on the Transfer Roller Assembly, to neutralize and
eliminate the charge to the print media.
10. Fixing:
Toner is fused onto the print media by the Fuser Assembly using heat
and pressure.
11. Cleaning:
During the general cleaning process, the voltage from the IDT rollers
and drums go through a cycle of changes to move the negative and positive charged
toner from IDT1 then IDT2 and then the transfer roller. The toner stored in the IDT 1
cleaner, the IDT 2 cleaner and on the transfer roller is removed and deposited into the
transfer roller waste recovery bin.
