How to Reset the Waste Ink Counter on an Epson EcoTank ET-2720

When an Epson EcoTank printer displays a message such as "ink pad is full," "maintenance required," or a similar waste ink warning, the printer is telling you that its internal waste ink counter has reached its limit. This warning can stop the printer from working, even if the printer still looks clean and has ink in the tanks. For many users, this message appears suddenly and creates confusion because the printer may have worked normally the day before.

Fortunately, this issue has two parts: the physical waste ink system and the electronic waste ink counter. The physical part involves the waste ink pad or waste tank area that collects ink during cleaning cycles. The electronic part involves the printer's internal counter, which estimates how much ink has gone into the waste area. Even after cleaning or replacing the sponge inside the waste tank, the printer may still show the error until you reset the counter.

In this guide, we will walk through how the waste ink system works, why the counter must be reset, and how to use the WIC reset utility from InkChip to reset the waste ink counter on an Epson EcoTank ET-2720. BCH Technologies works with printer repair, maintenance, and troubleshooting topics like this regularly, and this process is especially helpful for users who want to understand the repair before deciding whether to do it themselves or seek service.

We also have a video below to show how it's done, so you can follow the visual steps while reading the instructions.

Understanding the Waste Ink Counter

Epson EcoTank printers use cleaning cycles to keep the printhead nozzles clear. During these cycles, the printer pushes ink through the printhead and sends the extra ink into a waste ink area. This waste ink area may include pads, sponges, or a removable waste tank, depending on the printer model.

The printer does not usually measure the exact amount of ink inside the waste pad. Instead, it uses a counter. Each time the printer performs a cleaning cycle, charges ink, or carries out maintenance, the printer adds to this internal count. Once the counter reaches the preset limit, the printer assumes the waste ink area is full and displays a maintenance warning.

This system protects the printer and the surrounding workspace. If the waste ink sponge becomes overloaded, ink can leak inside the printer or onto the surface below it. Therefore, the warning should not be ignored. However, the warning also does not always mean the waste area is physically overflowing at that exact moment. It means the printer's internal estimate has reached the limit.

Because of this, you need to address both sides of the problem. First, you should inspect, clean, replace, or modify the waste ink collection area. Then, you need to reset the counter so the printer recognizes the maintenance work.

Why Cleaning the Waste Pad Alone Is Not Enough

Many users assume that once they clean or replace the waste ink sponge, the printer should automatically return to normal. Unfortunately, Epson printers do not usually detect that the sponge has been cleaned. The printer continues to rely on the counter stored in its internal memory.

For example, if the counter reads 100%, the printer will continue to show the maintenance error even if the waste tank sponge has been removed, washed, dried, or replaced. The physical condition of the sponge and the electronic counter are separate issues.

This is why a proper repair requires two steps. First, take care of the waste ink collection system. Some users clean the sponge inside the waste tank. Others replace the sponge with new absorbent material. Some repair shops install an external waste ink tank so the printer can send future waste ink into a container that is easier to monitor and empty. However, some customers may prefer to keep the printer in its original configuration rather than modify it.

After the physical maintenance is complete, reset the waste ink counter using a reset utility. Without this reset, the printer may remain locked in the maintenance error state.

What You Need Before Starting

Before resetting the waste ink counter, prepare the printer and computer. You will need the Epson EcoTank ET-2720, a computer, a USB cable, and access to the WIC reset utility. Although some printers support wireless printing, a USB connection is usually the safest choice for this type of maintenance because it gives the reset software a direct connection to the printer.

Start by placing the printer near the computer. Then connect the printer using a USB cable and turn the printer on. Make sure the printer has power and that the computer can recognize it. If the printer does not appear in the reset utility later, the connection may need to be refreshed, the USB cable may need to be changed, or the printer driver may need to be installed.

You should also confirm that the waste ink area has already been handled. Resetting the counter without cleaning, replacing, or redirecting the waste ink system can create a leak risk later. The counter reset tells the printer to continue operating, so the physical waste ink container must be ready to collect more ink.

In addition, keep in mind that reset utilities often require a reset key. This key is usually a long code. Because the code can be easy to mistype, copying and pasting it is better than entering it manually.

Downloading the WIC Reset Utility

To begin the reset process, go to InkChip's website and look for the WIC section. InkChip is commonly used for waste ink counter reset tools, and it provides versions of the WIC utility for different languages. Choose the language you can read comfortably so you can follow the prompts correctly.

After selecting the language, download the utility to your computer. Once the file appears in your downloads folder or on your desktop, open the English version if that is the language you selected. In some cases, the download may include multiple language versions, such as English, Spanish, Portuguese, Russian, or Turkish. Choose the correct version and ignore the others unless you need them.

When opening the utility, your computer may ask for permission to run the program. Review the prompt and allow the program to run if you trust the source and intend to proceed. After the utility opens, you should see options related to printer detection and waste ink counter functions.

At this stage, the printer should already be connected by USB and powered on. This helps the utility find the printer model accurately.

Detecting the Printer in the Utility

Once the WIC utility is open, look for the printer selection area. The software may include a refresh option, which helps it scan for connected printers. If the printer does not appear immediately, click refresh and wait for the program to detect it.

After detection, the software should show the Epson EcoTank ET-2720 or a similar model name. Make sure you select the correct printer before proceeding. This matters because reset utilities can support many printer models, and choosing the wrong one can cause confusion or prevent the reset from working.

Next, open the waste ink counter section. This area allows you to read the current counter value before making changes. Reading the counter first is a good practice because it confirms whether the waste ink counter is actually the reason for the maintenance error.

When the counter reads 100%, the printer has reached its programmed waste ink limit. The utility may display a message explaining that the counter has reached its limit and needs to be reset. This confirms that the printer is not just showing a random error. It is specifically reporting a full waste ink counter.

Reading the Waste Ink Counter

Before resetting anything, use the utility to read the waste ink counter. This step gives you a clear starting point. In the case of an ET-2720 with a maintenance required warning, the counter may show 100%. The software may also identify the counter as needing attention.

This reading helps you avoid unnecessary steps. For example, if the waste ink counter reads low but the printer still shows an error, the problem may involve something else, such as a paper jam sensor, scanner issue, firmware problem, or another maintenance condition. However, if the counter reads 100%, then resetting the waste ink counter is the correct next step after handling the waste pad or tank.

The utility may show more than one counter. Some Epson models track multiple waste ink values, such as a main pad counter and a platen pad counter. If the software shows several counters, read the displayed information carefully. Reset the counter related to the waste ink maintenance warning. When in doubt, review the instructions provided by the reset utility or seek professional support.

Entering the Reset Key Correctly

After confirming that the waste ink counter has reached its limit, choose the reset waste ink counter option. The utility will ask for a reset key. This key is usually long, and typing it manually can lead to mistakes. Even one incorrect character can prevent the reset from working.

The best method is to highlight the key, copy it, and paste it into the reset field. On most computers, you can use Control + C to copy and Control + V to paste. This reduces errors and makes the process faster.

After entering the key, continue with the reset command. The utility should process the reset and display a message when it finishes. In many cases, it will tell you to restart the printer to complete the reset process.

Do not skip the restart. The printer needs to power cycle so it can reload its internal settings and recognize the new counter value. Turn the printer off, wait briefly, and turn it back on.

Restarting the Printer After the Reset

After the reset utility confirms that the process is complete, turn off the printer. Let the printer shut down fully. Then turn it back on.

This restart is important because the counter reset may not appear immediately until the printer reboots. Once the printer powers back on, return to the WIC utility and read the waste ink counter again. This second reading confirms whether the reset worked.

If the reset completed successfully, the counter should show 0%, and the software should indicate that the counter is okay. At that point, the maintenance error should no longer block normal operation.

If the counter still shows 100%, check the USB connection, confirm that the correct printer was selected, and make sure the reset key was accepted. Also verify that the utility completed the reset rather than stopping due to a communication error.

Important Safety Notes Before Resetting

Resetting the waste ink counter does not remove ink from the printer. It only resets the printer's internal estimate. Therefore, never treat the software reset as the entire repair.

If the waste ink sponge is saturated and you reset the counter without addressing it, the printer may continue sending ink into an already full waste area. Over time, this can cause ink leakage, internal staining, or damage to nearby components. Waste ink can also make a mess on a desk, shelf, or floor.

For best results, inspect the waste ink tank or pad before resetting the counter. If the printer uses a removable waste tank, remove it carefully and check the sponge. Depending on the condition, you may clean and dry it, replace the absorbent material, or install a new tank. If the printer is used heavily, an external waste ink tank may be worth considering because it allows easier monitoring and maintenance in the future.

However, not every user wants an external tank modification. Some users prefer to keep the printer close to factory condition. In that case, servicing the internal waste sponge and resetting the counter may be enough, provided the sponge has enough capacity for future waste ink.

Common Problems During the Reset Process

Sometimes the reset utility does not detect the printer right away. When this happens, start with the basics. Make sure the printer is powered on, connected by USB, and not stuck in a sleep mode. Try a different USB port if needed. Also avoid using a USB hub, since direct connection often works better for printer utilities.

If the printer still does not appear, install or reinstall the Epson printer driver. A computer may print through a basic driver, but the reset utility may need proper communication with the device. Restarting the computer can also help if the USB connection has become unstable.

Another common issue involves the reset key. Because reset keys are long, manual typing often causes mistakes. Copy and paste the key whenever possible. Also make sure there are no extra spaces before or after the key.

In addition, do not disconnect the USB cable or turn off the printer while the reset is in progress. Interrupting communication during a reset can cause the software to fail. Wait until the utility displays a finished message before restarting the printer.

When to Seek Professional Help

Although the waste ink counter reset process is straightforward, not every printer issue should be handled without experience. If ink has leaked inside the printer, if the printer has multiple errors, or if the waste pad area is difficult to access, professional service may be a safer choice.

A repair shop can inspect the waste ink system, clean affected areas, replace absorbent material, and confirm that the printer is safe to operate. This is especially useful for printers used in business, production, sublimation, DTF-related workflows, or other high-volume printing environments.

BCH Technologies often focuses on practical printer repair methods because many printer problems can be solved with the right process and careful handling. However, the most important part is understanding what the warning means before resetting it. The reset should support the physical maintenance, not replace it.

Keeping the Printer Running After the Reset

After the counter reset, the printer should return to normal operation if no other errors are present. However, you should continue monitoring the printer. Watch for ink stains, unusual noises, repeated cleaning cycles, or new maintenance messages.

Try to avoid unnecessary printhead cleanings. Each cleaning cycle sends more ink into the waste system. If print quality problems appear, print a nozzle check first. Then use cleaning only when needed. If clogs continue, address ink flow, printhead condition, or air in the system rather than repeatedly running cleaning cycles.

Also place the printer on a surface that can tolerate minor ink accidents, especially after waste ink service. A protective mat or tray can prevent damage if an old waste pad or tube leaks unexpectedly.

With proper care, the Epson EcoTank ET-2720 can continue printing after the waste ink counter reset. The key is to treat the reset as part of a complete maintenance process. Clean or prepare the waste ink system first, reset the counter second, and verify the result afterward.

Final Thoughts

A waste ink warning on an Epson EcoTank ET-2720 can feel intimidating, but the issue becomes much easier to understand once you separate the physical waste ink system from the electronic counter. The printer stops because its internal counter has reached the limit, not necessarily because the printer is permanently damaged.

To restore operation, first handle the waste ink sponge or tank area. Then connect the printer by USB, open the WIC reset utility, read the waste ink counter, enter the reset key, reset the counter, restart the printer, and confirm that the counter reads 0%. This process clears the maintenance warning and allows the printer to continue working.
