Frequently asked questions (FAQ)
What is Epson C12C934591 and what is it for?
Epson C12C934591 is an original waste ink container (ink maintenance box). It collects excess ink produced during printing and print head cleaning in WorkForce ST-C8000, EcoTank Pro ET-16600/ET-16650/ET-5880/ET-5850/ET-5800 and L6550/L6570 printers.
When should the waste ink container be replaced?
Replace the container when the printer reports that the maintenance box is full or has reached the end of its service life. The container fills up over time depending on print volume and print head cleanings.
Is a waste ink container necessary?
Yes. When the container is full, the printer stops working until it is replaced. This is a normal maintenance item, not ink.
Does replacing the container affect the printer’s warranty?
No. Replacing the waste ink container is a normal maintenance operation and does not affect the printer’s warranty.
How fast is delivery?
Usually 1–2 working days across Estonia. A 14-day right of return applies.
Is the printer asking for maintenance?
If your Epson printer has stopped printing and shows a maintenance message, or the paper and ink lights are flashing, the waste ink pad may be full. Read about the causes and solutions on our blog: Epson L3250 and similar models — why the printer stops printing and what the waste ink pad is.
