Don't Ignore That Maintenance Box Warning
If your Epson printer is flashing a maintenance box warning — or has stopped printing entirely with a "Maintenance Box Full" error — you're not alone. This is one of the most common service stops for Epson wide-format printers, and the fix is straightforward once you know what you're dealing with.

What Is an Ink Maintenance Box?
Epson printers use an ink maintenance box (also called a waste ink pad or waste ink absorber) to collect excess ink from cleaning cycles and printhead purges. Over time, this box fills up. When it reaches capacity, the printer locks out to prevent ink overflow damage.
The Epson T04D1 is the maintenance box used in many Epson models. It is a sealed, user-replaceable unit.
Signs Your Maintenance Box Needs Replacing
- ⚠️ "Maintenance Box Full" error on the control panel or in the printer software
- ⚠️ Printer refuses to start a print job despite appearing ready
- ⚠️ Warning light flashing continuously (check your model's manual for the specific pattern)
- ⚠️ Ink odour near the printer — this can indicate the box is at or past capacity
- ⚠️ Maintenance box status shows "Expended" in the Epson Status Monitor
Important: Do not attempt to reset or clear the maintenance box counter without physically replacing the box. Overriding the sensor is a temporary fix that risks ink spillage inside the printer, causing permanent damage.

How to Check Maintenance Box Status
- Open the Epson Status Monitor on your computer (or use the printer's touchscreen if available).
- Navigate to Maintenance → Epson Status Monitor 3 (Windows) or the equivalent on macOS.
- Check the maintenance box level indicator. If it shows "Expended" or is near full, schedule replacement promptly.
How to Replace the Epson T6715 Maintenance Box
Tools needed: Lint-free gloves, a plastic bag for the used box.
- Power on the printer (replacement must be done with the printer on so it can reset the counter).
- Open the maintenance box compartment — typically located on the front or side of the printer (check your model's manual for the exact location).
- Slide out the old T6715 maintenance box. Handle carefully — it contains absorbed waste ink and can stain.
- Immediately place the old box in a plastic bag and seal it for disposal.
- Insert the new maintenance box until it clicks into place.
- Close the compartment. The printer should automatically reset the maintenance box counter.
- Confirm the status monitor now shows the box as operational.
Warning: Wear gloves throughout. Waste ink is difficult to remove from skin and clothing.
Frequently Asked Questions
Can I clean and reuse the maintenance box?
No. The maintenance box is a sealed unit not designed for cleaning or reuse. Attempting to do so risks ink contamination and damage to your printer.
How often does the maintenance box need replacing?
It depends on your print volume and how frequently the printer runs cleaning cycles. High-volume environments may need replacement every 6–12 months. Light users may go longer.
Will a third-party maintenance box work?
We recommend OEM parts for reliability. Compatible third-party options exist, but quality varies. Contact us if you have compatibility questions. Some of them may not contain the chip that resets the maintenance counter.
