See this chapter for detailed troubleshooting instructions if the printer is not working
properly.
3.1.1 First...
Before starting, confirm or attempt the following:
n
I carry out the confirmation of the obstacle contents with the liquid crystal display
message and light emitting diode display of operation panel.
n
There are no foreign materials inside the printer.
n
If the LCD display displays “Ready” when the power is on, print a status sheet.
Press the SelecType button twice to access the “Test Print Menu”, press the Item +
button until you see “Print Status Sheet”, and then press Enter.
By checking the Status Sheet you can determine whether the cause of the problem
is the printer itself (i.e. a part has been used beyond its useful life) or a user-
defined control panel setting.
n
The printer is not abnormally dirty. Clean if necessary.
n
The printer parts are original or EPSON replacement parts and no part of the
printer is deformed or out of shape in any way.
n
The connectors are properly fixed with no damage to them or any of the harnesses.
n
The cams and gears inside the printer are not worn, not wearing out unevenly, and
are connecting properly/turn freely.
n
The rubber pads on the rollers are not dirty. Clean if necessary.
n
The rubber pads on the rollers are not worn, not wearing out unevenly, and are
connecting properly/turn freely.
n
If necessary, reset the NVRAM parameters to the factory default parameters.
