Description
Compatible Models: Epson WorkForce Pro WF-4720, WF-4730, WF-4734, WF-4740.
What It Is: The Maintenance Box Count Chip (also called the Waste Ink Counter Chip) - a small memory chip that tracks how much waste ink the maintenance box/pad has absorbed and resets that count to zero. Without resetting this chip after replacing or emptying the maintenance box, the printer keeps reporting the box as full and refuses to print even with a fresh box installed.
Part Number: T6716 / T6715
Note: this catalog already carries a T6716/T6715 Maintenance Box listing (the box itself, not the chip) for the Epson WorkForce Pro WF-C529R/WF-C579R/WF-C5710/WF-C5790/WF-C5290/EcoTank ET-8700 family - a different WF-C model range from this row's WF-4720/4730/4734/4740 family. Epson does reuse the T6716/T6715 maintenance box across several WorkForce Pro generations, so both model ranges sharing this part number is plausible, but written here per this row's own stated models rather than merging the two lists.
