How to Replace the Toner
- Open the front cover of the printer.
- Pull out the used HP 26A or 26X cartridge.
- Unbox the new cartridge, rock it gently 5–6 times to distribute toner, and remove the protective seal.
- Slide the new cartridge in until it clicks into place.
- 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.
