Print Cartridge
The Print Cartridge receives image data in the form of pulsed laser light from
the Laser Scan Unit (LSU) and creates the image via the xerographic
process. The Print Cartridge contains the following components:
■ Charge Roller
■ Drum
■ Developer Roller (D/R)
■ Supply Roller (S/R)
■ Metering Blade
■ Cleaning Blade
Print Modes
The Phaser 3600 Laser Printer provides two print modes:
1. Draft mode: Uses a combination of reduced toner output and the lowest
resolution (300 x 300 dpi) to extend print cartridge life.
2. Enhanced mode: Used for printing on plain paper with an addressable
resolution of 1200 x 1200 dpi.
