Troubleshooting Outline 80
3.1 Outline
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:
There are no foreign materials inside the printer.
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.
The printer is not abnormally dirty. Clean if necessary.
The printer parts are original or EPSON replacement parts and no
part of the printer is deformed or out of shape in any way.
The connectors are properly fixed with no damage to them or any of
the harnesses.
The cams and gears inside the printer are not worn, not wearing out
unevenly, and are connecting properly/turn freely.
The rubber pads on the rollers are not dirty. Clean if necessary.
The rubber pads on the rollers are not worn, not wearing out
unevenly, and are connecting properly/turn freely.
If necessary, reset the NVRAM parameters to the factory default
parameters. Maintenance Mode 2 > Counter Init. Menu > NVRAM Init.
3.1.2 Remember
Before beginning disassembly turn the printer off, wait for a few seconds
after the LCD panel goes blank, and then remove the power cord from the
outlet. Also remove any interface cables.
