Epson ET-8550 Adjustment Program and Canon TM-200 Compatible Ink: What You Need to Know

Question:
I’ve been searching everywhere for the Epson ET-8550 adjustment program and can’t seem to find it online. Is there a reliable source you’d recommend? Also, I own a Canon TM-200 large-format printer and am looking to switch from OEM to third-party ink. Do you sell compatible ink for this model?

Answer:

Let’s go over your two questions in detail:

Epson ET-8550 Adjustment Program Availability

You're right—the adjustment program for the Epson ET-8550 (also known as the maintenance or service utility) is difficult to find online. Epson does not officially release these programs for consumer use, and most versions floating around on the internet are either outdated, incompatible, or unverified.

I am evaluating a version of the ET-8550 adjustment program, but I’m not comfortable recommending it until I can thoroughly test its safety and effectiveness. Until then, I recommend using WICReset—a reliable, trusted tool for Epson printers. WICReset supports a wide range of maintenance functions, including:

• Waste ink pad counter reset

• Ink charge

• EEPROM read/write

• Printhead ID assignment

• Head cleaning commands

While WICReset is a third-party service, it's well-supported and widely used in the Epson repair community.

Canon TM-200 Ink Compatibility

As for your Canon TM-200 large format printer, we understand the desire to move away from costly OEM cartridges. Canon's original ink, particularly the black pigment formulation, is known for its durability and depth—Canon holds patents on that formulation, making it difficult to replicate.

That said, you do have some cost-effective alternatives:

• For Cyan, Magenta, Yellow (CMY): You can use high-quality dye-based ink, which offers vibrant color output and excellent flow properties.

• For Black (K):

  • If you’re printing primarily on photo or coated media, you can substitute with dye black.

  • If you’re printing on matte or plain paper, consider using pigment black as a replacement.

At BCH Technologies, we manufacture and supply compatible inks by brand, not model-specific cartridges. This means our Canon-compatible inks are designed to perform across various Canon models, including wide-format printers like the TM-200.

Please visit our Ink for Printers section (https://bchtechnologies.com) to find suitable ink. Hover over “Ink for Printers,” choose your ink type (dye or pigment), and then select the size and format that fits your needs.

Addressing printer maintenance and ink replacement decisions often involves hands-on evaluation and experimentation. Unfortunately, because of the varied nature of printer firmware and hardware across regions, we cannot offer remote diagnostics or provide third-party software recommendations with complete confidence. However, we do offer a professional in-person printer evaluation service (https://bchtechnologies.com/printer-repair-service), which operates on a first-come, first-served basis. Turnaround times may vary depending on demand. While we understand that our pricing may not be the most economical, our services cover complete unit assessments or targeted part repairs. We also encourage DIY troubleshooting and maintenance, which you can explore via our YouTube channel homepage (https://youtube.com/@bchtechnologies). Use the search icon under the “About” tab to find videos relevant to your model or issue.
