T671400 Maintenance Box
The T671400
Maintenance Box is a
critical maintenance accessory for users of high-volume inkjet printers like
Epson WorkForce WF-C878R, WF-C879R, WF-C8190, WF-C8690, and WF-C869R. During
regular printing — especially when print-head cleaning or purge is triggered —
excess ink is flushed out and needs to be redirected safely. This maintenance
box collects that waste ink securely, preventing it from accumulating inside
the printer, which could otherwise lead to clogging, internal damage, or print
errors.
Equipped with a built-in reset chip, this box
ensures that the printer correctly recognizes the replacement, avoiding error
messages or “maintenance box full” warnings. Installation is straightforward:
remove the old maintenance box, insert the new one, and the printer resets its
waste-ink counter, no special tools is required.
For businesses, offices, or print-intensive
environments, using this maintenance box regularly helps maintain print
consistency, prevents downtime, and extends the overall service life of the
printer. This is especially valuable for bulk printing tasks, as it ensures
that maintenance cycles remain hassle-free and efficient.

Q1. Which Epson printers are
compatible with this maintenance box?
A1. This maintenance box is compatible with Epson WorkForce series printers
including WF-C878R, WF-C879R, WF-C8190, WF-C8690, and WF-C869R.
Q2. What happens if I don’t replace
the maintenance box when full?
A2. If the maintenance box becomes full and isn’t replaced, excess ink may
overflow inside the printer, causing clogs, print errors, or even internal
damage. It also triggers maintenance warnings and may halt printing.
Q3. Is installation difficult — do I
need special tools?
A3. No special tools are required. The maintenance box with chip is designed
for easy installation: simply remove the old box and plug in the new one. The
printer automatically resets the waste-ink counter.
