Primary Charge Roller for Kyocera MC-4105, model 302NG93050

The Primary Charge Roller for Kyocera MC-4105, model 302NG93050 is a replacement imaging component designed to restore and maintain even electrostatic charging across the photoconductor in Kyocera MC-4105 multi-function printers. It supports consistent toner attraction and helps reduce print defects such as streaks, banding, and uneven density by providing uniform surface potential during the charging step of the xerographic process.

Advantages

This primary charge roller is manufactured to match the charge characteristics required by the Kyocera MC-4105, ensuring stable charging performance and predictable wear. Replacing a worn or damaged roller improves first-page-out consistency, reduces background shading, and contributes to more reliable print runs. The part is suitable for professional service and routine maintenance, enabling technicians to return devices to specified print quality parameters.

Suitable for

• Service and preventive maintenance of Kyocera MC-4105 printers
• Replacement of worn or damaged primary charge rollers to correct image defects
• Repair workflows in print shops, office IT departments, and maintenance centers

Key specifications

• Function: primary charge roller for uniform electrostatic charging of the photoconductor
• Compatibility: Kyocera MC-4105 series
• Material characteristics: conductive roller surface designed for consistent charge transfer
• Form factor: replacement roller sized to fit the printer’s charging assembly
• Intended use: imaging subsystem component subject to wear and periodic replacement

How to use

Install the replacement roller following the Kyocera MC-4105 service manual instructions or manufacturer-recommended service procedure. Power off the printer and allow access to the imaging unit according to safety guidelines. Remove the imaging unit or drum cassette as applicable, disengage the old roller from its mounts, and fit the new roller in the same orientation and seating. Reassemble components, verify correct installation, and run a calibration or conditioning cycle if the printer supports it to stabilize charge behavior before regular printing.

Usage recommendations

Replace the primary charge roller when print quality issues such as consistent streaking, uneven density, or increased background shading are observed, or as part of scheduled maintenance intervals. Use proper electrostatic discharge (ESD) precautions during handling, avoid contaminating the roller surface with oils or solvents, and follow manufacturer guidelines for disposal and replacement frequency to maintain optimal printer performance.
