Compatible Red Ink for SendPro Mailstation

This cartridge replaces the Pitney Bowes SL-870-1 ink supply for SendPro Mailstation (CSD1) postage meters. It is manufactured by American Mailing Solutions as a USPS-certified alternative to the original equipment cartridge. The red fluorescent ink is formulated to meet postal requirements for meter impressions. One cartridge is supplied per box.

Drop-in Cartridge Design

The unit installs directly into the SendPro Mailstation meter without tools or adapter kits. Its physical interface matches the OEM SL-870-1 form factor, so daily operation remains unchanged for mailroom staff. The supplier states the ink will not damage the meter mechanism and that using this cartridge does not void the postage meter warranty. Each box contains a single replacement cartridge.

Yield Range of 400 to 880 Impressions

The cartridge is rated for 400 to 880 postage impressions per fill, matching the OEM yield specification. Actual output varies with print density settings and the proportion of graphics versus text on each mail piece. High-volume mailrooms should plan for more frequent replacements than low-volume users. The cartridge is not intended for printers or label makers outside the SendPro Mailstation series.
