Epson printers issue beep tones when certain error conditions exist. Those beeps
can assist you in locating and repairing customer’s printers. The following error
codes are listed by product name.
NOTE:
Most of the beeps issued by the printers are of .1 second duration with a .1
second pause between beeps. Where the beeps or the pauses are longer,
it has been noted in the text. The description “3 Beeps x 2” means two sets
of three beeps.

inform the user of problems. The following messages will help you to
troubleshoot problems.
A blank LCD screen with the Power-on LED lit can be caused by a bent

A ‘Verify After Write” check to the SRAM has failed. The SRAM could be bad.
This is a motor control error. Four possible areas of failure are:
a. CR home condition not detected at power up
b. Platen gap motor HP not detected correctly
c. Friction/Tractor feed switching error
d. Physical obstruction such as a jammed ribbon
Skewed paper detect error. Since the initial reading upon loading a single
sheet paper, the paper has skewed. This is a printhead wire protection
feature.
Illegal paper positioning.
(1)
If the paper is loaded using the knob instead of the LOAD/EJECT switch,
this error condition will occur. This is a printhead wire protection feature.
(2)
PE sensor may have failed or is not connected.
CPU error. An undefined op-code was detected.
NOTES:
Error codes 11 and 12 are usually caused by new operators who are
un-familiar with the machine. Both of these errors are corrected by
turning the printer off, taking out the paper and turning the printer back
on. Both features were added to ensure proper paper handling and
prevent paper jams, which can result in printhead failures.
Incorrect jumper settings on the ROMA board may cause errors 10 or
20. The correct settings are documented in the Service Manual (page
A-54, figure A-52) and on TIB LQ2550-005.
Errors 0,2, 3, 10, and 20 may require a repair, adjustment or
replacement.

P-0007
SUBJECT: LQ-800/1000 IBM GRAPHICS CHARACTER PRINTING
Here at Product Support we receive numerous questions about
the printing of IBM-type graphics on the LQ-800/1000 printers,
and about the difference between the ESC/P and IBM identity
modules.
The purpose of this bulletin is to address these
common questions.
Printing IBM Graphics Characters
The LQ-800/1000 cannot print the IBM graphics characters unless
it has either the ESC/P (#7696) or the IBM (#7695) identity
module installed.
Module Differences
Various options are available when using the identity modules,
depending on which is used.
The ESC/P provides the character
graphics forms from the IBM standard character set, as well as
Greek alphabet characters,
and some mathematical operation
symbols.
In comparison,
the IBMmodule has the Alternate
and Symbol character sets, in addition to the standard set.
These may be required for some applications.
Software commands also differ between the two modules.
The
ESC/P module will allow use of all standard Epson printer
commands normally available to the LQ printers, whereas the
IBM module causes the LQ printer to emulate an IBM 5152
printer,
with the loss of some Epson printer commands normally
available to the LQ.
All font modules are usable with either identity module.
