On Windows, install the XP-2100 with Epson's driver, not Microsoft's. Download it from Epson's website for this model. If Windows set the printer up by itself with a Microsoft driver (Windows Ready Print or Microsoft IPP Class Driver), it may still print, but the tool often can't read or reset it over USB.

How the XP-2100 tells you
The XP-2100 has no screen for messages, so it reports ink pad problems with lights. When the ink and paper lights flash at the same time, Epson says an ink pad is nearing or at the end of its service life. Flashing one after the other points to the borderless pad. Connect it with a USB cable to read and reset the counter.
What the XP-2100 lights mean
Not every blinking light is the ink pads. Only the rows marked “Yes” are fixed by resetting the counter.
| Lights | What Epson says it means | Fixed by a reset? |
|---|---|---|
| Ink and paper lights flash at the same time | An ink pad is nearing or at the end of its service life. If a message on your computer says you can continue, press a copy button to keep printing. The lights flash again at regular intervals until the pad is replaced | Yes |
| Ink and paper lights flash one after the other | A borderless printing ink pad is nearing or at the end of its service life. Printing with a border still works | Yes |
| Paper light flashes slowly | A paper jam. Remove the paper and press a copy button | No |

XP-2100 questions
My XP-2100 ink light is on. Is that the ink pad?
Not by itself. Epson's guide lists the ink light alone for a cartridge that is expended, missing or not recognized. The ink pad pattern is the ink and paper lights flashing together, or one after the other.
Does a reset empty the ink pads?
No. A reset only clears the counter. The ink already in the pads stays there, so check them before you keep printing for a long time.
Is this the Epson XP-2100 Adjustment Program?
No. The Adjustment Program is Epson's Windows service software for technicians, one per model, with many service functions. VNIT Reset Tool only reads and resets the XP-2100's waste ink counters, on Windows and Mac, which is all the ink pad error needs.
The free trial worked. Do I still need a key?
Not straight away. The trial leaves the counter at 80%, so the error comes back sooner than after a full reset to 0% with a key.
My Epson XP-2100 stopped printing. Is it the ink pads?
It can be. When a waste ink counter reaches its limit, the printer stops printing until the counter is reset. Press Check Printer in VNIT Reset Tool to read the counter for free: if it is at or near 100%, that is the cause. If the counters are low, look elsewhere, such as the driver, the print queue or the print head.
Is this the same as "reset ink levels" or a factory reset on the XP-2100?
No. Resetting ink levels is about the ink tanks, and a factory reset puts settings such as the network back to default. Neither clears the waste ink counter. This page is about the waste ink counter only.
