How to Reinstall the Carriage Belt on an Epson WF-7725 Without Removing the Carriage: A Step-by-Step Guide

Customer Question:

I’m trying to reinstall the carriage belt on my Epson WF-7725 All-in-One printer. The belt slipped off the carriage, and I’d like to know if there’s a way to fit the carriage belt back without having to remove the carriage assembly. Any tips?

Answer:

When the carriage belt comes off its track, many assume that disassembling the entire carriage mechanism is necessary—but fortunately, that’s not always the case. On the WF-7725 model, the carriage belt is tensioned using a pulley system located on the left-hand side of the printer.

Here's how you can reattach the belt without removing the carriage:

1. Access the Pulley Mechanism:

   • Open the top cover of your printer and locate the pulley on the left side. This pulley holds the tension spring that keeps the belt in place and taut.

2. Relieve Tension from the Belt:

   • Carefully remove the tension spring from the pulley mechanism. This will loosen the belt, giving you more room to work with.

3. Reposition the Belt:

   • Re-seat the belt around the carriage and the pulleys. Make sure the belt teeth are correctly aligned with the gear teeth on both ends.

4. Reattach the Spring:

   • Once the belt is securely in place, reattach the spring to the pulley. This will restore tension to the belt system.

5. Final Check:

   • Gently move the carriage back and forth to ensure smooth movement and proper belt alignment. The motion should be fluid with no jerks or resistance.

A helpful visual reference for this process can be found in one of our YouTube discussions, specifically in this video guide (https://www.youtube.com/watch?v=oRRFFXcKSX8).

Additional Notes:

• Avoid forcing the carriage if it's stuck or misaligned, as this could damage the encoder strip or belt teeth.

• If you're unsure about tension levels after reattachment, listen for abnormal sounds during startup or test prints; this might indicate improper alignment or tension.

A Final Word:

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. Therefore, we're unable to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis. Therefore, it may take a few weeks before we can arrange for your printer to drop it off. Our services are structured to repair either the whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage (https://youtube.com/@bchtechnologies). Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be the most efficient approach. Additionally, YouTube may suggest relevant videos from other channels that can assist you.

Thank you again for contacting us—we appreciate your trust and hope this guide helps you get your printer back up and running quickly!
