NOTES
The LQ-2500 is only supported with tractor paper. This is because in single sheet
mode or CSF mode the printer has a large top and bottom non-printable area.
For best results you should print at 360 x 180 DPI for normal printing and 180 x
180 DPI for draft printing.

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 .I second duration with a .l
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.

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 PROMS or jumper Jl may be set incorrectly.

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.
Enors 0,2, 3, 10, and 20 may require a repair, adjustment or
replacement.

Subject : LQ - 2550 Error Codes 11 and 12
Date: 4/11/90 PSB No: P-0064
Page: 1 of 1 Originator: ASB
There are two new error codes which can occur in printers with ROM version
022287 or higher. They are error 11 and error 12.
Error 11 indicates that the paper is not straight.
Error 12 indicates that the paper was loaded using the platen knob instead of the
LOAD/EJECT button.
When these errors occur, the printer stops, the audible alarm sounds, and one
of these two error messages will appear on the front panel.
The solution to both of these errors is the same. Follow the steps below:
1. Turn the printer off.
2. Remove the paper. (Use the platen knob if necessary.)
3. Turn the printer back on.
4. Load the paper using the LOAD/EJECT button as described in the manual.
OR
4. If you are using a sheet feeder, begin printing again. The printer automatically
loads the paper.
NOTE: Use the platen knob only for removing jammed paper. Never use it when
you are loading paper. Use the LOAD/EJECT button for loading the paper.

If the power requirements of a particular Epson printer is not listed please
refer to the appropriate User's Manual for the electrical specifications.
In the event that the User's Manual is not available, locate the silver label
on the back of the Epson printer.
This is a reliable source for the electrical
requirements.
The following formula is used to calculate the electrical
power requirements:
VOLTAMPS is equivalent to WATTS
VOLTAMPS = Volts * Amps
AMPS
BTU/HR
= Voltamps/Volts
= Watts * 3.413
Example:
120V * 1A
= 120VA
120VA/120V
= 1A
120VA is equivalent to 120W
120W * 3.413 = 409.56 BTU/HR
Heat output is rated in BTU/HR.
