Summit Postal Products Black K2 Ink Cartridge 250 ml

Compatible Black Cartridge for FP Envelope Printers

This Summit Postal Products cartridge replaces the FP M1INKBLACK and works with FP Edge, FP Edge Pro and FP Double Edge colour envelope printers. It contains 250 ml of 100% FP compliant black dye-based ink and is supplied as a single pack. The plug-and-play design allows straightforward installation without additional setup steps.

Practical limits of the FP cartridge interface

The cartridge is built exclusively for the listed FP envelope printer models and will not fit or function in other printer families. It uses a proprietary form factor and ink formulation matched to the FP printing system, so cross-brand compatibility is not possible. Users must confirm their exact printer model before purchase to avoid fitment issues.

250 ml black dye-based ink volume

The 250 ml fill determines how many envelopes can be printed before replacement is needed, making it the key figure for workload planning. Offices with high daily mailing volumes will reach the end of the cartridge sooner than low-volume users. If your operation requires a larger or smaller ink supply, this specific capacity may not match your replenishment cycle.
