Epson ET-4800 "Waste Ink Container" Message: Reliable Ways to Reset the Counter and Keep Your Printer Running

Question: My Epson ET-4800 shows a "waste ink container" (maintenance) message. Is there a reliable way to reset the counter so the printer doesn't shut down and force me to buy a new one?

I'm using an Epson EcoTank ET-4800 and the waste ink container / maintenance message came up again. I've dealt with it before, and at one point I even routed waste ink to an external bottle-but that doesn't seem to stop the message from returning.

Is there any way to reliably reset the waste ink counter in the printer? I've seen tools online, but I don't know what I can trust. I'm frustrated because it feels like I get about two years out of the printer before it blocks itself and I'm forced to replace a perfectly good machine.

Answer: 

What the "waste ink container / maintenance" message actually means

Your ET-4800 tracks a waste ink counter internally. During normal operation (especially cleanings, priming, and power cycles), ink is pumped into an internal absorbent pad system (sometimes referred to as "waste ink pads"). The printer doesn't measure how wet the pads are-it estimates waste ink accumulation and triggers a shutdown or warning once it believes the pads are near their service limit.

Common wording varies by model/region, but you'll often see messages like:

• "Waste ink container is full"

• "Maintenance required"

• "Ink pad is at the end of its service life"

• "Service required" (often accompanied by the printer refusing to print)

Even if you route waste ink externally, the printer may still display the message because:

1. The printer still counts purge/cleaning ink in its memory, and

2. Some designs still send at least part of the waste ink internally, and/or the counter still assumes it did.

So you're exactly right: the external bottle can help manage the mess and reduce internal saturation risk, but it does not automatically reset the counter.

The most reliable "reset" is done with a reputable waste-ink counter reset utility

We don't sell reset software or reset keys, but if your goal is a reliable counter reset, two well-known services in the printer community are:

• InkChip [https://inkchip.net]

• WIC Reset / WIC Support [https://wic.support]

These providers typically offer a utility plus a paid reset key/code for supported Epson models. In many cases, the process looks like this:

1. Install the utility on a computer.

2. Connect the printer by USB (USB is often more reliable than Wi-Fi for maintenance functions).

3. Let the tool read the printer's waste ink counter.

4. Purchase/apply a reset key (if required).

5. Reset the counter to bring the printer back online.

Important note: The reset clears the printer's memory of estimated waste ink-it does not remove ink from pads. That's why it's essential to think about the "physical" side too (next section).

Also, while InkChip and WIC Support are widely used, always review terms carefully. Third-party utilities can affect warranty status and-depending on your location-there may be consumer/warranty implications. We recommend reading their documentation and contacting their support if anything looks unclear.

Don't skip the physical reality: saturated pads can cause real problems

Resetting the counter without addressing the physical waste ink situation can lead to:

• Ink overflow inside the printer

• Smearing/leaks under the unit

• Strong ink odor, staining, or damage to surfaces

• Electrical contamination if ink spreads into sensitive areas (worst case)

If your printer truly has a lot of waste ink accumulation, you generally have two practical paths:

Option 1: Proper pad service (best practice)

This means disassembling enough of the printer to access and replace/clean pads (model-dependent). This is the "factory-correct" approach, but it can be time-consuming and messy.

Option 2: External waste bottle (very practical for many users)

An external waste bottle can be an effective solution to redirect waste ink so you're not relying entirely on internal pads. If you've already done this, great-you were thinking in the right direction. Just keep in mind: you still need the counter reset to clear the lockout message.

Regarding external bottle sizing: BCH Technologies offers external waste bottles in 2.5 mm and 4.0 mm options. For many Epson desktop units, the actual internal tubing connection is commonly 2.5 mm, but drilling/port size preferences and different setups can make either kit workable depending on how you route the line. In practice, many users choose based on how large of an exit hole they want and how they plan to secure the tubing path.

A special case: some printers/waste systems require a chip-based reset method

On certain Epson designs, a "waste ink tank" or maintenance component may include a chip (or a chip-driven maintenance box concept). In those cases, you may run into situations where:

• A software reset alone isn't enough, or

• A specific reset routine/device is needed, or

• The model uses a different maintenance architecture than expected

If your ET-4800 is presenting the "waste ink container" message in a way that behaves like a chip-locked component, your best move is to use a utility that explicitly lists ET-4800 compatibility and provides clear instructions for that exact message.

Recommended step-by-step approach (reliable and realistic)

1. Confirm your exact model: ET-4800 (not ET-4750 or ET-4850), because compatibility matters.

2. Use a reputable tool such as InkChip [https://inkchip.net] or WIC Support [https://wic.support] to read the waste ink counter first (before buying anything).

3. If supported, purchase/apply the reset key and perform the reset using USB if possible.

4. Physically manage waste ink (pads serviced and/or external waste bottle) so resetting the counter doesn't create a future leak/overflow situation.

5. After reset, reduce unnecessary cleanings: repeated head clean cycles are one of the fastest ways to drive the waste ink counter up again.

Addressing printer issues can be complicated because many problems are hands-on and depend on the exact condition of the unit. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We do offer an in-person evaluation and repair service through our local diagnostic facility: Printer Repair Service [https://bchtechnologies.com/printer-repair-service]. Due to high demand, we operate first-come, first-served, and it may take a few weeks before you're able to drop the printer off. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed. That said, we understand our rates aren't the most economical-so we strongly encourage self-help through online research. A great starting point is YouTube, including our YouTube channel homepage [https://youtube.com/@bchtechnologies]. Use the search icon next to "About" on the right side of the menu bar to find videos by keyword. I receive dozens of questions daily asking if we have a video for a specific issue, and after nine years of creating videos, it's hard to remember every single one-YouTube search is the fastest method. Plus, YouTube may also recommend helpful videos from other channels that match your exact situation.

Thanks again for contacting us, and thank you for supporting BCH Technologies. If you decide to reset the counter, please take the physical waste ink side seriously as well-doing both together is the most reliable way to keep your ET-4800 running instead of replacing a perfectly good printer.
