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.

1 beep: BEL code
1 beep: A Control Panel setting is accepted.
3 beeps: Paper End detected
5 beeps: Abnormal carriage movement
On-Line light is flashing: Printhead is over heated. Carriage will stop until
the printhead cools down.

NOTE: Printers with LCD displays use error messages along with beeps to
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
pin on one of the PROM S or jumper J1 may be set incorrectly.

LQ-2550 LCD Codes:
00 (1)
The font could not be found. The printer’s internal program could not
find the target font.

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.

Quick Reference for Printer Acoustic Noise Levels
Date: 6/5/91
PSB No: P-0016D
Page(s): 1 of 2 Originator: SLS
Sound intensity is measured in units called Bels (named after Alexander Graham Bell,)
or more commonly in tenths of this fundamental unit: decibels. In making noise
measurements a weighting network is applied in an attempt to match the frequency
response of the instrument to that of the human ear. The most common is the A
weighting network, with resulting measurements expressed in dB(A).
The following is a list of current product’s noise levels tested in accordance with
standards set by the International Standards Organization (ISO). The acoustic noise
levels for the 9 pin printers are averages while printing in Near Letter Quality (NLQ)
mode using continuous paper and are not guaranteed figures. The acoustic noise
levels for the 24 pin printers are averages while printing in Letter Quality (LQ) mode
using continuous paper and are not guaranteed figures. The acoustic noise levels for
the laser printers are averages while using single sheet paper and are not guaranteed
figures.
