Epson WF-C5390: replace the maintenance box or reset its chip

The WF-C5390 collects waste ink in a replaceable maintenance box with a chip (C9382). When the box is full, the fix is a new box, or a chip resetter (a small tool that resets the box’s chip). No PC reset software, ours included, applies to this model.

How the WF-C5390 tells you

When its maintenance box is full, the WF-C5390 stops printing and asks you to replace the maintenance box. The count is kept on the box's chip, which is why a new box clears the message.

What to do

1. Check the code printed on the box in your printer. It should read C9382.
2. Buy a replacement C9382 box. Genuine Epson boxes and compatible boxes with a new chip are both sold.
3. Swap the box following your printer's manual. The printer reads the new chip and the message clears.

Or reset the box’s chip

A chip resetter for C9382 is a small tool you touch to the chip on the box; it sets the box’s count back to empty so the printer accepts it again. It is a hardware tool, not software. It does not empty the box: only reuse a box whose absorbent pad is not soaked, or you risk ink leaking inside the printer.
