PLEASE READ CAREFULLY BEFORE PURCHASING

This is a compatible NON-OEM product. It is not manufactured, sponsored, endorsed, or warrantied by Pitney Bowes.

Before purchasing, confirm your exact postage-meter model and verify that your machine uses an SL-798-0 or SL-793-5 ink cartridge. Model numbers alone may not guarantee compatibility because cartridge requirements can vary by machine configuration and region.

If the machine does not recognize the cartridge:

1. Remove the cartridge.
2. Confirm that all protective covers and shipping materials have been removed.
3. Turn off and disconnect the machine from power for several minutes.
4. Reinstall the cartridge securely.
5. Reconnect the power and restart the machine.
6. Follow any on-screen installation prompts.

A cartridge-recognition message does not necessarily mean the cartridge is defective.

By purchasing this item, you acknowledge that you have read the compatibility information above and understand that these are compatible, non-OEM ink cartridges.
