Chapter 6 Problem Solver; Diagnosing The Problem; Using The Error Indicators - Epson PLQ-20 Reference Manual

Diagnosing the Problem

For problems that may be related to USB connections, see
"Correcting USB Problems" on page 115 for details.
If your problem is not USB related, troubleshooting printer
problems is best handled in two easy steps; first diagnose the
problem, then apply likely solutions until the problem is fixed.
The information that you need to diagnose and solve most
common problems is provided by the printer's control panel,
EPSON Status Monitor 3, or by printing a self-test or hex dump.
Refer to the appropriate section below.
If you have a specific problem relating to print quality, a printout
problem not related to print quality, or a paper feeding problem,
or if the printer does not print at all, refer to the appropriate
section in this chapter.
To solve a problem, you may need to cancel printing. For details,
see "Canceling Printing" on page 67.

Using the error indicators

You can identify many common printer problems using the lights
on the control panel. If your printer stops working and one or
more control panel lights are on or flashing or the printer beeps,
use the following table to diagnose and fix the problem. If you
cannot fix your printer problem using this table, see "Problems
and Solutions" on page 105.
Note:
The printer beeps once if you press a control panel button when the
corresponding function is not available.
