Compatible Red Fluorescent Ink Cartridge

This two-pack provides a USPS-approved red fluorescent ink cartridge built for the SendPro Mailstation CSD1 postage meter. It serves businesses and home offices that process outgoing mail and need a lower-cost supply option. Each cartridge is manufactured to work with the meter without voiding the original warranty.

Low-Maintenance Consumable Operation

The ink formulation is designed for clean, reliable printing during normal daily mailing tasks. No special power, cooling or noise considerations apply to this consumable. It installs directly into the meter and runs quietly as part of the standard print cycle.

Consistent Yield Over Extended Runs

Each cartridge delivers up to 400-880 impressions, matching OEM output for sustained mailing volumes. The supply maintains print quality across the full rated yield rather than fading after a short burst. The two-pack format supports continuous operation without frequent reordering.

Questions about this item

How do I install the SL-870-1 cartridge in my SendPro Mailstation, and what step is often missed?

Open the meter cover, remove the empty cartridge, insert the new SL-870-1 until it clicks, then close the cover; the step often missed is forgetting to remove the protective tape from the print head before insertion.

What maintenance or replacement will the red fluorescent ink cartridge need later?

The cartridge is a single-use supply yielding up to 400-880 impressions; when print quality fades or the meter signals low ink, replace the entire cartridge with a new SL-870-1 unit.

What limit appears first during sustained high-volume mailing with this cartridge?

The ink yield limit of up to 880 impressions is reached first; after that the cartridge must be replaced to continue printing postage.
