The Ultimate Guide to SendPro® P / Connect+® Ink Cartridges and Supplies

If your business relies on a SendPro® P or Connect+® Mailing System, keeping the right ink cartridges on hand is essential. From ensuring USPS compliance to presenting a professional image, the right supplies keep your mailroom running smoothly.

In this guide, we’ll cover everything you need to know about ink cartridges and bundles for SendPro® P / Connect+® systems, including which ones to use, how to choose between standard and large capacities, and how color options can improve your brand’s mail presence.

Why the Right Ink Matters

Mailing systems aren’t just about printing postage. Every cartridge you use affects three important factors:

• Compliance: USPS requires crisp, legible red indicia.
  
• Professionalism: Clear addresses and graphics reflect your brand.
  
• Efficiency: High-yield cartridges reduce downtime and save money.
  

That’s why offices of all sizes rely on cartridges like the Red Ink Cartridge (Standard) for SendPro™ P / Connect+® (Item #787-0), which delivers consistent, compliant postage marks for everyday mail.

Red Ink Cartridges: Standard, Production, and Large

Red ink is mandatory for postage marks, but not all cartridges are created equal.

• Everyday mailing: The Red Ink Cartridge (Standard) (Item #787-0) is the go-to choice for small offices with steady mailing needs.
  
• High-volume operations: The Red Ink Cartridge (Production) (Item #787-1) supports heavier throughput without sacrificing clarity.
  
• Maximum efficiency: The Red Ink Cartridge (Large) (Item #787-8) helps cut back on frequent replacements, perfect for businesses handling thousands of envelopes each week.
  

By choosing the right size, you balance cost with convenience and avoid unnecessary downtime.

Black and Yellow Cartridges for Mailroom Flexibility

Red may handle the postage, but black and yellow cartridges give your mailroom more options.

The Black Ink Cartridge (Large) for SendPro® P / Connect+® (Item #787-3) is ideal for printing return addresses, barcodes, and other critical details directly onto envelopes. It keeps every piece looking sharp and professional.

For businesses adding branding or emphasis, the Yellow Ink Cartridge (Standard) (Item #787-F) adds vibrancy. Logos, highlights, and colored elements stand out immediately, making your communications more memorable.

Enhance Branding with the Color Graphics Bundle

Beyond basic ink, the Color Graphics Bundle (Item #78P-Z) lets you print logos, marketing messages, and graphics directly onto envelopes. Instead of sending plain mail, you can create branded communication that captures attention the moment it’s delivered.

This option is especially valuable for marketing-driven businesses or any office looking to strengthen brand recognition through every piece of mail.

How to Choose the Right Cartridge

The right cartridge depends on your mailing volume and goals:

• Small offices → Red Ink Cartridge (Standard) is sufficient for daily letters.
  
• Growing teams → Red Ink Cartridge (Production) balances volume with efficiency.
  
• Large mailrooms → Large Red Ink Cartridge and Large Black Ink Cartridge reduce downtime.
• Brand-focused businesses → Pair Yellow Ink Cartridge with the Color Graphics Bundle for professional, eye-catching mail.
  

Maintenance and Cost Tips

• Store cartridges in a cool, dry place until use.
  

• Run test prints regularly to prevent drying.
  

• Don’t wait until the cartridge is empty—quality drops quickly.
  

• Invest in larger cartridges if you mail at high volumes; they lower cost per impression.
  

Final Thoughts

Your SendPro® P / Connect+® system is only as effective as the ink you put in it. From the reliable Red Ink Cartridge (Standard) to high-capacity options like the Large Red Ink Cartridge, and from practical Black Ink Cartridges to branding solutions like the Color Graphics Bundle, choosing the right supplies ensures compliance, efficiency, and professionalism in every piece of mail you send.
