Which Waste Ink Tank Kit Should I Use for My Epson ET-7750? A Detailed Guide for the Right Fit

Customer Question:
I’m planning to install a waste ink collection kit on my Epson ET-7750. I noticed that there are different sizes, such as 25 mm and 40 mm. Which version of the kit should I select to ensure compatibility?

Answer:
Thank you so much for reaching out to us! We sincerely apologize for not being able to get back to you sooner. We completely understand that printer problems can feel urgent and frustrating, and that’s why we want to handle each case with the attention and detail it deserves.

Here at BCH Technologies, we’re always grateful for your support, especially on our YouTube channel [https://youtube.com/@bchtechnologies]. Your thoughtful questions help us improve our products and resources, and allow us to deliver better solutions to everyone in our community.

Now, let’s tackle your question regarding the waste ink tank kit for your Epson ET-7750.

Understanding the Correct Kit Size

Although you’ll see options labeled as 25 mm and 40 mm on our X-Large Waste Ink Collection Tank Combo product page [https://bch-youtube-fan-store.myshopify.com/products/xlarge-waste-ink-collection-tank-combo-with-small-tube-for-epson-as-ep-waste-25mm], it’s essential to clarify what these mean in your case.

The Epson ET-7750 uses a waste ink tube with a diameter of 2.5 mm. The reference to “25 mm” in the SKU is a formatting shorthand and does not reflect the actual tube size. The product’s included connector is a dual-size connector, specifically designed to accommodate both 2.5 mm and 4.0 mm tubes. So, both options will physically fit your printer—you’re covered either way!

However, if you prefer a more straightforward installation without using any adapters, we recommend selecting the 2.5 mm kit.

Resetting the Waste Ink Counter

Installing the waste ink tank will solve the physical overflow issue, but your printer’s firmware will eventually display a warning like:

• “Service required”

• “Ink pad at end of service life”

• “Parts inside your printer are at the end of their service life.”

To clear these errors, you’ll need to reset the waste ink counter using software. We recommend using Inkchip’s WIC reset utility [https://inkchip.net/wic] for the following reasons:

• Simple and user-friendly interface

• Reasonably priced reset keys

• Compatible with most Epson models, including the ET-7750

Alternatively, WICreset is another software option that works similarly.

Important note:
If your ET-7750 is a model that includes a chip on the waste tank, software reset won’t work. In that case, you’ll need to identify the tank model and purchase a physical resetter specific to it. Most consumer-grade ET-series printers do not have waste tank chips, but it’s best to verify just in case.

The Role of the Waste Ink Tank

Remember, the waste ink tank kit is simply a mechanical container to hold discharged ink. It doesn’t contain any sensors or chips. Its purpose is to:

• Prevent overflow of internal pads

• Allow easy maintenance without disassembling the printer

• Extend the usable life of your printer without costly service visits

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.

Thanks again for your thoughtful question and for being part of our growing community. We appreciate your trust in BCH Technologies, and we’re always here to help you keep your printer running at its best!
