■ Configuration
Parts Configuration
The cartridge of this machine is drum integrated type and forms a visible image on the Photosensitive Drum with toner.
• Photosensitive Drum
• Developing Assembly
• Primary Charging Roller
• Memory tag
• Toner level sensor
Drive Configuration
DC Controller drives the Drum Motor (M2) to rotate the Photosensitive Drum and the Developing Roller. The Primary Charging
Roller is driven and rotated by the Photosensitive Drum.
■ Cartridge State Detection
Purpose
DC Controller detects and memorizes the state of the cartridge by reading/writing the data saved in the Cartridge Memory.
When the Cartridge Memory cannot be detected or non-genuine/incorrect cartridge is detected, the DC Controller notifies the
Main Controller and displays a warning message.
Overview
The cartridge of this machine is equipped with the Cartridge Memory, and the status of a cartridge can be detected by reading
the information on it.
Execution Condition/Timing
• When the door is closed after replacement of the cartridge.
• At power-on (excluding high-speed start mode)
Process name
Laser beam exposure With irradiation of laser beam, a static latent image is formed on the surface
of the Photosensitive Drum. (Image exposure: Area exposed by laser is the
image area)
Development With the dry, 2-component AC developing method, toner that has been
negatively charged by the Developing Cylinder is attached to the Photo-
sensitive Drum.
Transfer Toner on the Photosensitive Drum is transferred to a paper.
Separation With the curvature separation method, the paper is separated from the ITB.
Thin paper's elastic force is small, so the electric charge of the paper surface
at the back is weakened with the Static Eliminator to be separated easier.
Fixing Toner on the paper is fixed on the paper using heat and pressure.
Drum cleaning The Cleaning Blade removes the residual toner attached on the Photosen-
sitive Drum.
