What Toner Does the HP LaserJet Pro M402dn Use?

The HP LaserJet Pro M402dn is a monochrome laser printer that uses the HP 26A (CF226A) standard-yield toner cartridge or the HP 26X (CF226X) high-yield toner cartridge. The cartridge has an integrated drum, so there is no separate drum unit to replace.

How to Replace the Toner

  1. Open the front cover of the printer.
  2. Pull out the used HP 26A or 26X cartridge.
  3. Unbox the new cartridge, rock it gently 5–6 times to distribute toner, and remove the protective seal.
  4. Slide the new cartridge in until it clicks into place.
  5. Close the cover. The printer will recognize the new cartridge automatically.

Troubleshooting Tips

  • "Replace Toner" or low-toner warning: HP cartridges report level via chip. If a known-good cartridge shows low or non-genuine warning, try power-cycling the printer or updating firmware.
  • Faded or streaky prints: Gently rock the toner cartridge side-to-side to redistribute toner, then reinstall. Run the printer's built-in cleaning page from the maintenance menu to clear fuser residue.
  • Print quality declining over time: Because the drum is integrated, replacing the toner cartridge installs a fresh drum at the same time — no separate drum service required.
  • Paper jams or smudges: Inspect the paper path and pickup roller for wear. Replacing worn rollers and keeping the printer dust-free prevents repeated print-quality issues.
