Message: [QUOTE="micheal349, post: 230844, member: 27745"] To remove and inspect the [B]drum unit[/B] from the [B]Fuji-Xerox DocuPrint CM215[/B] (also applies to CM215fw and CM215b), follow these steps carefully. The drum is part of the [B]drum/toner cartridge unit[/B], so you will need to handle it as such. [HR][/HR] [HEADING=2]⚠️ BEFORE YOU START:[/HEADING] [LIST] [*][B]Turn off[/B] the printer and [B]unplug[/B] 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 [B]light for long periods[/B] (cover it with paper if needed). [/LIST] [HR][/HR] [HEADING=2]✅ STEP-BY-STEP: Removing the Drum Unit[/HEADING] [LIST=1] [*][B]Open the Front Cover[/B] Lift open the front panel where you normally access the toner cartridges. [*][B]Remove the Toner Cartridges[/B] [LIST] [*]Pull out each of the toner cartridges (Cyan, Magenta, Yellow, Black) one by one. [*]Place them on a clean surface (avoid scratching the rollers). [/LIST] [*][B]Remove the Drum Unit[/B] [LIST] [*]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. [/LIST] [*][B]Inspect the Drum[/B] [LIST] [*]Look for any obvious marks, toner buildup, scratches, or smudges on the green drum surface. [*]Rotate the drum gently using the side gear—[B]do not touch the green drum with fingers[/B]. [*]Use a dry lint-free cloth or soft brush to gently clean loose toner. [/LIST] [/LIST] [HR][/HR] [HEADING=2]Optional: Clean the Drum (Carefully)[/HEADING] If you see toner marks, use a [B]soft cloth lightly dampened with isopropyl alcohol (90%+)[/B] to wipe gently. Dry it immediately after. If the mark is etched or persistent, the drum may be worn out and need replacing. [HR][/HR] [HEADING=2]Reinstalling the Drum[/HEADING] [LIST=1] [*]Slide the drum unit back into the printer. [*]Reinsert each toner cartridge into its slot. [*]Close the front panel. [*]Plug in and power on the printer. [*]Run a test print to see if the smudge is gone. [/LIST] [HR][/HR] [HEADING=2]Tip:[/HEADING] If the smudge repeats at regular intervals, it may be a [B]fuser[/B] or [B]drum[/B] issue. If it’s irregular, it might be debris inside. Cleaning the drum and interior carefully usually helps. [/QUOTE]
