Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your ONLYU 142A W1420A compatible toner cartridge. Please read these instructions carefully before use to ensure optimal performance and longevity of your product.
Printer Compatibility
The ONLYU 142A W1420A toner cartridge is designed for precise fit and consistent results with specific HP LaserJet printer models. Please verify your printer model before installation.
Compatible Models:
- HP LaserJet M110 series (e.g., M110w)
- HP LaserJet M139 series (e.g., M139w, MFP M139)
- HP LaserJet M140 series (e.g., M140w, MFP M140w)
Models such as M110we, M139we, and M140we do not require HP+ registration or firmware updates to use this cartridge, provided the HP+ service is not activated.

Important Note on HP+ Service:
Activating the HP+ service may restrict your printer to using only original HP cartridges, preventing the use of compatible cartridges and potentially increasing printing costs. It is recommended to carefully consider the HP+ service before activation.

Maintenance
To ensure the best performance and extend the life of your toner cartridge and printer:
- Store unused cartridges in their original, sealed packaging in a cool, dry place away from direct sunlight.
- Avoid exposing the toner cartridge to extreme temperatures or humidity.
- Do not touch the green drum roller on the cartridge, as oils from your skin can cause print defects.
- Regularly clean your printer according to its manufacturer's instructions to prevent toner buildup and maintain print quality.
Troubleshooting
Common Issues and Solutions:
- Printer Not Recognizing Cartridge:
Ensure the cartridge is fully seated in its slot. Remove and reinsert it. Check for any protective tapes or covers that might have been missed during installation. If your printer is an 'e' series model (e.g., M110we, M139we, M140we) and you have activated HP+ service, it might be locked to original HP cartridges. - Poor Print Quality (Faded, Streaky, or Spots):
Gently shake the toner cartridge from side to side to redistribute the toner. Ensure the sealing tape was completely removed. Check if the drum roller is clean and free from fingerprints or debris. If the issue persists, the cartridge may be low on toner or defective. - Error Messages:
Refer to your printer's user manual for specific error codes. For 'non-genuine cartridge' messages, you can usually bypass these by pressing 'OK' or 'Continue' on your printer. If the error persists and prevents printing, ensure your printer's firmware has not been updated to restrict compatible cartridges, especially if you have an 'e' series model.
