Compatible Maintenance Box for Epson C9344 (C12C934461 / T212 / EWMB3)

Get your Epson printer back to printing with the PRM Compatible Maintenance Box. This is a direct replacement for the original Epson C9344 — clearing the "Maintenance Box Full" error and restoring normal printing immediately.

Looking for an Epson L3550 maintenance box, Epson L5590 maintenance box, or Epson L3560 maintenance box? The C9344 is the correct maintenance box for all Epson EcoTank, Expression Home, and WorkForce printers listed below.

What is a Maintenance Box?
The maintenance box is a small absorbent pad container that collects excess ink during printing, head cleaning, and borderless printing. Over time, this pad fills up with waste ink. When it's full, your printer displays a "Maintenance Box Full" or "Maintenance Box End of Service Life" error and stops printing completely — even if your ink tanks are full.

This is not a malfunction. It's a routine consumable replacement, just like replacing ink. The maintenance box is designed to be swapped out when full.

When Do You Need a New Maintenance Box?
Replace your maintenance box when you see:
- "Maintenance Box is Full" error on the printer display
- "Maintenance Box End of Service Life" message
- Printer stops printing completely and refuses all print jobs
- Warning message that the maintenance box is "nearly full"
- Ink pad counter reached 100% in the printer utility software

Don't wait for the box to reach 100% — once the error appears, the printer will not print a single page until the maintenance box is replaced. If you see a "nearly full" warning, order a replacement now so you have it ready.

1. Instant Fix — Clear the Error, Start Printing: Remove the full maintenance box, insert the new one, and the error clears automatically. Your printer resets the ink pad counter and is ready to print immediately. The entire swap takes under 2 minutes.

2. Fits a Wide Range of Epson Printers: The C9344 is used across Epson's EcoTank, Expression Home, and WorkForce printer families. Whether you have the popular L3550 ink tank printer or a WorkForce MFP, this is the correct maintenance box.

3. Compatible Quality, Same Function: The maintenance box is an absorbent pad in a plastic housing — there is no electronic component or print quality difference between original and compatible. It collects waste ink. A compatible box does this identically to the original at a fraction of the price.

4. No Chip Issues: This compatible maintenance box comes with the chip pre-installed. Your printer will recognise it immediately — no error messages, no workarounds needed.

5. Easy Installation: Open the maintenance box cover (usually on the right side or rear of the printer), slide out the old box, slide in the new one, and close. Under 2 minutes. No tools needed. Handle the old box carefully — it's full of waste ink.

6. Tested Before Shipping: Every PRM maintenance box is checked for proper fit and chip function before dispatch. Backed by our testing warranty.
