Symptoms: Printer displays "Cartridge not recognized," "Replace cartridge," or "Cartridge missing."
Solutions:

• Remove and reinstall the cartridge firmly.
• Power cycle the printer (turn off, unplug for 1 minute, plug back in, restart).
• Gently clean the chip contacts with a lint-free cloth and isopropyl alcohol.
• Confirm the cartridge model is compatible with your printer.
• Check for any recent firmware updates that may affect recognition.

Symptoms: Faded prints, streaks, lines, or smudges on pages.
Solutions:

• Gently shake the cartridge side to side to redistribute toner.
• Run the printer's cleaning cycle (found in your printer settings).
• Ensure all protective seals or tape are fully removed.
• Inspect the drum unit (if separate) for damage or toner buildup.
• Try a test print — if issues persist, the cartridge may be faulty.

Symptoms: Toner powder inside the printer or on printed pages.
Solutions:

• Carefully remove the cartridge and inspect for leaks or visible damage.
• Clean the inside of the printer with a soft brush or electronics-safe vacuum.
• Discontinue use and request a replacement cartridge if leaking continues.

Symptoms: Printed pages come out completely blank.
Solutions:

• Ensure all protective seals have been removed from the cartridge.
• Reinstall the cartridge securely.
• Test with another cartridge if possible to isolate the issue.

Symptoms: "Low toner" message immediately after installation.
Solutions:

• Continue printing — many remanufactured cartridges work past early warnings.
• Override low toner settings if your printer allows it.
• Monitor print quality and request a replacement if needed.

Symptoms: Persistent "replace cartridge" message even after installation.
Solutions:

• Reset the printer or unplug it briefly to clear memory errors.

Symptoms: Cartridge feels loose or won’t lock into place.
Solutions:

• Double-check that the cartridge model matches your printer model.
• Compare it to the original OEM cartridge for any visible differences.
• Inspect clips and tabs for damage; request a replacement if needed.

• Store cartridges in a cool, dry environment.
• Handle cartridges carefully — avoid touching the green drum.
• Monitor firmware updates and check compatibility if needed.
