Waste ink counters on the L3150
VNIT Reset Tool reads and resets these counters on the L3150. The printer stops when a counter reaches its limit.
| Counter | What it is | Limit |
|---|---|---|
| Main pad | The main absorber pad inside the printer body | 6,346 points |
| Platen pad | The pad near the paper path, used by borderless printing | 3,416 points |
The tool shows each counter as a percentage of its limit. 100% means full.
How the L3150 tells you
The L3150 has no screen. When a waste ink pad counter is full, its power and paper lights flash at the same time and printing stops. It prints over Wi-Fi, but reading and resetting the counter needs a USB cable.
What the L3150 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? |
|---|---|---|
| Power and paper lights flash at the same time | An ink pad is nearing or at the end of its service life | Yes |
| Power and paper lights flash one after the other (alternately) | The borderless printing ink pad is nearing or at the end of its service life | Yes |
| Paper light flashes (on its own) | Paper is jammed in the printer | No |
| Paper light on | No paper, or several sheets fed at once | No |
| All lights flash | Paper or protective material is stuck inside. Open the front cover and remove it | No |
| Wi-Fi and Wi-Fi Direct lights flash | Wi-Fi connection error. Press the Wi-Fi button to clear it | No |
| Power light flashes | The printer is busy. Wait | No |

L3150 questions
Why are the power and paper lights blinking on my L3150?
Flashing together, or one after the other, they point to the ink pads, which this tool resets. The paper light alone means a paper jam. Reading the counter for free tells you which counter is full.
It is the power and paper lights, not the ink light. Is it still the ink pads?
Yes. On the L3110 and L3150, Epson uses the power and paper lights for the ink pads: flashing together for the main pad, one after the other for the borderless pad. This is different from the L3210, which uses the ink and paper lights.
Which counters does it have?
Two: the Main pad and the Platen pad (used by borderless printing). The tool shows each one as a percentage, and Reset all clears them in one go.
Can I reset the L3150 over Wi-Fi?
Use a USB cable. The L3150 prints over Wi-Fi, but reading and resetting the waste ink counter over Wi-Fi works on a few models only.
Is this the Epson L3150 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 L3150'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 L3150 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 L3150?
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.
