Step-by-Step CLT-R406 Rebuild & Chip Installation
- Remove the Unit: Open the front cover, remove the toner cartridges and the waste toner bottle. Pull out the CLT-R406 imaging unit (the large assembly with the green roller) from the printer.
- Disassemble the Housing: Carefully unscrew the side frames to access the internal rollers. Take note of the position of the springs and high-voltage contacts.
- Replace Drum and Blade: Remove the old, worn-out OPC drum and the cleaning blade. However, you must thoroughly vacuum out the waste toner compartment. If left full, the new blade will fail immediately.
- Installation: Install the new cleaning blade first, then the new OPC drum. Ensure the drum surface is clean and lubricated with a small amount of toner to prevent initial friction damage.
- Adding the Reset Chip: Since many starter units lack a chip, you must install a new CLT-R406 chip in the designated slot. This tells the printer’s firmware that a new unit has been installed, resetting the life counter to 100%.
- Testing: Finally, reassemble the unit and perform a test print. The “Replace Imaging Unit” error should disappear, and your prints should be crisp and clear.

Expert Tip
When installing the new chip, ensure it is seated firmly and oriented correctly. If the printer still doesn’t recognize the unit, clean the gold contacts on the printer side with a cotton swab and alcohol. Sometimes a simple restart of the machine is required to refresh the chip data.
