Pitney Bowes Ink Cartridges: 797-M, 797-0, 765-9, and 793-5

Every mailroom has one rule: keep the postage meter running. For businesses using Pitney Bowes systems, the ink you choose determines how smoothly that workflow goes. From compact Mailstation™ meters to versatile DM Series machines and the newer SendPro™ C Series, each setup requires a specific cartridge to keep postage crisp and USPS-compliant.

Here’s how the most important Pitney Bowes red ink cartridges — 797-M, 797-0, 765-9, and 793-5 — fit into the picture.

797-M & 797-0 – Red Ink for Mailstation™ and Mailstation2™

The Pitney Bowes 797-M and 797-0 Cartridges are purpose-built for the Mailstation™ and Mailstation2™ systems. These smaller, desktop-friendly meters are popular with small offices, and this ink ensures every envelope carries a clear, USPS-approved red imprint.

Compatible systems: Mailstation™, Mailstation2™
Best fit: Low to moderate mailing volumes
Why it matters: Without the 797-M/797-0, Mailstation models can’t deliver the compliant red postage impressions required by USPS.

If you’ve outgrown the Mailstation and moved to a DM Series meter, you’ll need to step up to cartridges like the 765-9 or 793-5.

765-9 – Red Ink for DM300C™ and DM400C™

The 765-9 red ink cartridge is designed for the DM300C™ and DM400C™ series meters — machines made for mid-level mailing. Offices using these meters send more mail than a Mailstation user but don’t yet need the capacity of the larger enterprise setups.

Compatible systems: DM300C™, DM400C™
Best fit: Medium-sized offices, steady daily mailing
Why it matters: This cartridge keeps impressions sharp and professional, ensuring compliance without overspending on high-yield models.

Think of the 765-9 as the natural step up from the 797-M/797-0 once your mailing needs exceed the Mailstation level.

793-5 – High Yield Red Ink for DM100™, DM200™, and SendPro™ C Series

The Pitney Bowes 793-5 high-yield cartridge covers some of the most versatile meters: DM100™, DM200™ series, and SendPro™ C Series. These machines are used in busier mailrooms, and the cartridge’s high yield means fewer replacements and lower cost per impression.

Compatible systems: DM100™, DM200™, SendPro™ C Series
Best fit: High-volume mailing, larger teams, frequent use
Why it matters: Unlike the 765-9, the 793-5 extends cartridge life, reducing downtime in environments where productivity counts.

If you’re running a SendPro™ C Series system, this is the cartridge engineered specifically for its higher throughput.

Choosing Between Them

This breakdown shows how each cartridge aligns with the system family it was built for — and why using the wrong one can lead to compliance issues, wasted money, or downtime.

Maintenance Tips for Pitney Bowes Ink

Store sealed cartridges in a cool, dry place.
Run a test print if mail volume is low to prevent clogs.
Replace before the cartridge runs dry to avoid streaks or faded impressions.

Final Thoughts

From the compact Mailstation™ models with the 797-M/797-0, to the mid-level DM300C/DM400C with the 765-9, and the high-output DM100™, DM200™, and SendPro™ C Series powered by the 793-5 high yield, Pitney Bowes ink cartridges are matched exactly to the machines they support.
