PostBase Ink Cartridge Breakdown: Find the Best Fit for Your Mailing System
Every office has that one machine you can’t afford to let sit idle. If you handle postage daily, it’s the PostBase mailing system. Whether you’re running a compact PostBase Mini or a larger PostBase setup, having the correct ink cartridge ready is the difference between smooth operations and a frustrating stack of unsent envelopes.
The catch? Not all cartridges are the same. Some are made for light office use, while others are designed for heavy workloads. Choosing wrong can waste money, cause faded impressions, or lead to downtime.
Let’s break down the three key PostBase ink options—PMIC10, PIC10, and PIC40—and see where each fits best.
PMIC10 – PostBase Mini Ink Cartridge
The PMIC10 is designed for the PostBase Mini system. Think of it as the everyday cartridge for small offices that don’t handle high volumes of mail.
- Machine compatibility: PostBase Mini
- Impression range: Designed for light use
- Best for: Small businesses or teams mailing a few hundred envelopes a week
The PMIC10 is affordable, easy to replace, and keeps impressions clear and compliant with USPS standards. If your mailing needs are steady but light, this is the cartridge to keep on hand.
PIC10 – PostBase Standard Capacity Ink Cartridges (2-Pack, 4,000 Impressions)
For medium-sized offices, the PIC10 standard capacity cartridge strikes the right balance. Sold as a 2-pack, it delivers up to 4,000 impressions total.
- Machine compatibility: PostBase models using standard cartridges
- Capacity: 4,000 impressions (combined)
- Best for: Businesses with consistent but moderate mailing
Think of the PIC10 as your “daily driver.” It’s more cost-effective than repeatedly buying Mini cartridges, and it ensures crisp, professional postage on every envelope. Perfect if you’re mailing a few thousand items per month.
PIC40 – PostBase High-Capacity Ink Cartridges (2-Pack, 18,000 Impressions)
For high-volume operations, the PIC40 high-capacity ink cartridge is the powerhouse. This 2-pack lasts for up to 18,000 impressions, reducing the number of times you’ll need to stop and swap out cartridges.
- Machine compatibility: PostBase models requiring high-capacity ink
- Capacity: 18,000 impressions (combined)
- Best for: Large mailrooms and businesses handling thousands of envelopes per week
The PIC40 isn’t just about convenience. With fewer replacements and a lower cost per impression, it’s the economical choice long term.
Which PostBase Cartridge Should You Choose?
- PMIC10 (Mini Cartridge): Best for light mailing needs, smaller offices
- PIC10 (Standard Capacity): Ideal for medium-sized businesses with steady volume
- PIC40 (High Capacity): Built for heavy mailrooms where efficiency matters most
By matching your cartridge to your actual mailing volume, you save money, reduce downtime, and keep your PostBase system running at peak performance.
Maintenance Tips to Extend Cartridge Life
- Store cartridges in a cool, dry place until use
- Run a test print if your volume is low, so ink doesn’t clog
- Replace before they’re bone-dry to avoid streaks or faded impressions
Final Thoughts
Your PostBase mailing system is designed to make sending mail effortless—but only if you use the right supplies. From the PMIC10 for the Mini, to the PIC10 for standard capacity needs, and the PIC40 for heavy mailing, there’s a cartridge for every business. Choosing the right one ensures your mailroom stays efficient, professional, and USPS-compliant.
