The Epson L100 is a discontinued single-function ink tank printer.
It was replaced with the EcoTank L300.
The unit was introduced along with the L200.

The latter is a multifunction model with the same high-capacity ink tank system.
Features and Highlights
The history behind Epsons decision to make the two printers is rather interesting.
Thats where they got the idea to build ink tank printers, which includes the L100 and L200.

The only downside of the tanks is that they are attached to the side of the printer.
About Epson L100 Resetter
The printers ink pads are at the end of their service life.
This is the message that may show up on your screen after the printer fails to print.

The L100 doesnt check whether the pad is black or not.
Instead, it checks the state of the pads by employing a counter.
The message that you see on your box screen is triggered by this counter.
Epson L100 Resetter resets the counter so that the message wont show up again.
