2. Product Specifications and Description

2.5.3. Imaging Unit

The imaging unit is an integrated type. The Imaging Unit consists of the drum, developer, and Drum Cleaning Sections.
Each section is constructed together at the time of production and is not designed to be disassembled. Therefore the Imaging
Unit must be ordered as an assembled part. Since it is a "Sales Option", please order though our sales channel.
The OPC drum diameter is 30 mm (circumference: about 94.2 mm).
The deve roller must keep the regular Nip to prevent the image defect. The Nip Ring is used for this.
After the image is moved to transfer roller, the remaining toner on the OPC drum is removed by the cleaning blade.
The imaging unit has a CRUM that stores the series number and maintenance count information.
