Fuji-Xerox DocuPrint CM215 drum removal

[CM215query]

I have owned this laser MFC machine since new (longer ago than I can remember) and it continues to perform well, but I want to remove the drum to inspect it for something which is causing a small smudge mark on printed material.

(The smudge mark appears at various points on printed pages, hence my suspicion that it is caused by something on the drum.)

After numerous Google searches on this topic, I have found nothing. Hopefully, someone on this Forum can help!

To remove and inspect the drum unit from the Fuji-Xerox DocuPrint CM215 (also applies to CM215fw and CM215b), follow these steps carefully. The drum is part of the drum/toner cartridge unit, so you will need to handle it as such.

BEFORE YOU START:​

• Turn off the printer and unplug it for safety.
• Let the machine cool down for 10–15 minutes if it was recently used.
• Prepare a clean, lint-free cloth and a flat surface to place the drum on.
• Avoid exposing the drum to light for long periods (cover it with paper if needed).

STEP-BY-STEP: Removing the Drum Unit​

1. Open the Front Cover
   Lift open the front panel where you normally access the toner cartridges.
2. Remove the Toner Cartridges
   • Pull out each of the toner cartridges (Cyan, Magenta, Yellow, Black) one by one.
   • Place them on a clean surface (avoid scratching the rollers).
3. Remove the Drum Unit
   • The drum unit is the assembly that the toners sit in.
   • Grab the sides of the drum unit and gently pull it straight out.
   • If there's resistance, ensure the toners are fully removed and nothing is blocking the path.
4. Inspect the Drum
   • Look for any obvious marks, toner buildup, scratches, or smudges on the green drum surface.
   • Rotate the drum gently using the side gear—do not touch the green drum with fingers.
   • Use a dry lint-free cloth or soft brush to gently clean loose toner.

Optional: Clean the Drum (Carefully)​

If you see toner marks, use a soft cloth lightly dampened with isopropyl alcohol (90%+) to wipe gently. Dry it immediately after. If the mark is etched or persistent, the drum may be worn out and need replacing.

Reinstalling the Drum​

1. Slide the drum unit back into the printer.
2. Reinsert each toner cartridge into its slot.
3. Close the front panel.
4. Plug in and power on the printer.
5. Run a test print to see if the smudge is gone.

Tip:​

If the smudge repeats at regular intervals, it may be a fuser or drum issue. If it’s irregular, it might be debris inside. Cleaning the drum and interior carefully usually helps.
