Epson printer message: "The maintenance box is at the end of its service life"

Quick answer

The maintenance box must be replaced before printing can continue. Unlike the ink pads, the maintenance box is a user-replaceable part — though Epson states it is not covered by the product warranty.

Caution: This step can be done wrong in a way that is costly or hard to undo, including voiding your warranty. Check your model's manual before proceeding.

Before you try the solution

  1. 1. Copy the complete message exactly as shown, including any code, letters, or punctuation the panel puts around it.
  2. 2. Find the printer's exact model number. The same-looking code can mean something different on another model family.
  3. 3. Let the current print, scan, or update operation stop before touching controls, paper paths, or covers.

Manufacturer-documented solution

The maintenance box must be replaced before printing can continue. Unlike the ink pads, the maintenance box is a user-replaceable part — though Epson states it is not covered by the product warranty.

Model scope: The maintenance box part number Epson lists for your exact model, for example T04D100 or C9344

If the error is still there

  1. 1Return to the screen or job that produced the message and check whether the code has cleared.
  2. 2If "The maintenance box is at the end of its service life" returns, do not repeat a risky procedure. Record when it appears and check the documentation for the exact model.
  3. 3Because this message involves opening the printer, service risk, or possible damage, stop and contact Epson support or a qualified printer technician if it persists.
