Red fluorescent ink cartridge for SendPro

This red fluorescent ink cartridge is a compatible replacement for the Pitney Bowes SL-870-1 model used in the SendPro Mailstation postage meter. It is designed for businesses that process outgoing mail and need a cost-effective supply of USPS-approved red ink. The cartridge is manufactured by American Mailing Solutions Inc. and comes individually boxed.

USPS-certified formulation protects the meter

The ink is specially formulated for the SendPro Mailstation (CSD1) and carries USPS certification, ensuring the meter prints valid postage indicia. Rigorous quality assurance testing during manufacturing aims to prevent print-head clogging or internal leaks that could damage the machine. Using this compatible cartridge does not void the postage meter's original warranty.

This cartridge directly replaces the OEM SL-870-1 supply at a lower cost per impression. The jump is worth it for mailrooms that want to reduce consumable spend while maintaining the same print quality and meter compliance. Each unit yields up to 880 impressions, with a minimum expected yield of 400 impressions depending on mailpiece coverage.
