Compatible HP & Xerox Drum Units: Long-Lasting Print Quality at a Fraction of the Cost

Laser printers and digital copiers from HP and Xerox rely on an imaging drum unit to transfer toner onto the page, and unlike a toner cartridge, a drum unit typically lasts through several toner refills before it needs to be replaced. When it does wear out, genuine OEM drum kits can cost as much as some printers themselves. Our compatible drum units are built to match OEM page yield and image quality, giving you the same crisp, consistent output at a fraction of the price.

HP & Xerox Drum Unit FAQs

Which drum unit does my HP or Xerox printer use?

Drum unit compatibility is model-specific. The HP Color LaserJet 4500, 4550, CM6030, and CP6015 series use the HP C4195A drum kit, while the HP Color LaserJet CM6030f, CM6040f, and CP6015 series also use the HP 824A drum units (CB384A black, CB385A cyan, CB386A yellow, CB387A magenta). Xerox Document Centre, WorkCentre, and Digital Copier models use the Xerox 13R551 drum unit. Check your printer's model number or the label on your current drum, then search it above to confirm the exact match.

How long does a drum unit typically last?

Compatible drum units are engineered to match OEM-rated page yield, which typically ranges from 15,000 to 30,000 pages depending on the model, and drums generally outlast several toner cartridge refills before needing replacement. Because a drum wears down gradually with each print cycle, you'll typically notice a decline in print quality well before it fails completely.

Will using a compatible drum unit void my printer's warranty?

No. Under the Magnuson-Moss Warranty Act, manufacturers cannot void your printer's warranty simply because you used a third-party drum unit.

What are signs that my drum unit needs to be replaced?

Common warning signs include repeating spots or streaks appearing at regular intervals on the page, a gradual fading or graying of print quality, ghost images faintly repeating from previous pages, or streaks running the length of the page. If you notice these issues even after replacing the toner cartridge, the drum unit is likely due for replacement.

How should I handle and store a drum unit to avoid damage?

Store spare drum units in their original packaging, away from direct sunlight and extreme temperatures. Avoid touching the green photosensitive drum surface, since oils from your fingers can leave permanent marks that show up on printed pages. If your printer will sit unused for an extended period, remove the drum unit and store it in a sealed bag to protect it from dust and light exposure.
