The Epson ColorWorks C4000 Maintenance Box is a required consumable for the Epson ColorWorks C4000 label printer with gloss ink and the Epson ColorWorks C4000 label printer with matte ink. It is a sealed unit that collects waste ink generated during printhead cleaning cycles and routine maintenance operations. When the box reaches capacity the printer will stop printing entirely until it is replaced. Most printers display an early warning when the box is approaching full, giving you time to order a replacement before it becomes an urgent issue. Part numbers: SJMB4000 / C33S021601 Compatible with: Epson ColorWorks CW-C4000 (gloss and matte configurations) Note: This maintenance box is the correct consumable for the C4000 only. It is not compatible with other ColorWorks models. Save on repeat orders with our Subscribe & Save program. You get 3% off when you set up automatic delivery. No contracts, cancel any time.
