Maintenance Box, TM-C3500

The Epson C33S020580 maintenance box is a replacement waste ink container for the ColorWorks C3500 color inkjet label printer. Epson identifies the maintenance box in the TM-C3500 series guide as model SJMB3500.

It collects waste ink discharged during printing and cleaning. When the printer indicates that the box needs replacement, the used unit can be removed and a replacement installed in its place.

This part is intended for the Epson ColorWorks C3500. It helps keep routine printer maintenance focused on replacing the waste ink container when the printer signals that it is needed.
