OPC drum unit MCZ3937 for Canon iR2016 / iR2020 / iR2018 printers

OPC drum unit MCZ3937 is a photoconductor designed as a replacement imaging component for Canon imageRUNNER models iR2016, iR2020 and iR2018. The drum unit transfers toner to paper during the electrophotographic printing cycle and is a regular consumable for maintaining consistent print density, sharp text and defined graphics. This replacement unit is intended for use in office printers and print service environments where OEM-equivalent parts are required for routine maintenance and consumable refresh.

Advantages

The OPC drum MCZ3937 restores image contrast and uniformity across pages by providing a stable photosensitive surface. It supports predictable page yield and helps reduce streaking, banding and uneven toner distribution when installed and inspected as part of scheduled maintenance. The unit is compatible with the listed Canon imageRUNNER models and is suitable for use where a direct-fit, functional replacement is needed.

Suitable for

• Office printers in small to medium-sized workgroups
• Print service and reprographic environments requiring consistent output
• Routine maintenance and consumable replacement cycles
• Environments aiming to maintain OEM-equivalent print quality at lower cost

How to use

Replace the existing drum unit following the printer manufacturer's service instructions: power off the device, open the access panels, remove waste toner or toner cartridges as recommended, carefully extract the end-of-life drum unit and install the MCZ3937 drum until it seats securely. After installation, reassemble panels and run any required printer initialization or calibration procedures to restore optimal print density and alignment.

Usage recommendations

Handle the drum surface carefully to avoid fingerprints or scratches; store unused units in a cool, dry place away from direct light. Inspect related consumables such as toner cartridges and cleaning components when replacing the drum to ensure balanced performance and consistent print quality.
