Error
Code
Description
09
COPROCESSOR COMMUNICATION ERROR – The main microprocessor is not communicating
with the interface coprocessor. The interface coprocessor may be in a fault condition with the host
or just not able to respond. This error may appear when the scanner is configured for USB or
RS485 interface applications or during an attempt to update the interface software through the
flash utility. The unit should be repaired at an authorized service center.
11
SWITCH ERROR – The switch used for volume selection or sleep mode is detected in error
(always closed). The condition is self-correcting if possible. If the error persists, return the unit for
repair at an authorized service center. The scanning operation can continue with this error active.
21
LASER #1 (VERTICAL) ERROR – The laser in the vertical scanning subsystem denotes a failure.
The scanner will try three times to correct the laser operation. If the laser error persists, the
vertical scanning subsystem will be shut down and this error code will remain on the Diagnostic
Indicators.
22
LASER #2 (RIGHT HORIZONTAL) ERROR – The right laser in the horizontal scanning subsystem
denotes a failure. The scanner will try three times to correct the laser operation. If the laser error
persists, and the left horizontal laser (#3) is also in error, the horizontal scanning subsystem will be
shut down and this error code will remain on the Diagnostic Indicators.
23
LASER #3 (LEFT HORIZONTAL) ERROR – The left laser in the horizontal scanning subsystem
denotes a failure. The scanner will try three times to correct the laser operation. If the laser error
persists, and the right horizontal laser (#2) is also in error, the horizontal scanning subsystem will
be shut down and this error code will remain on the Diagnostic Indicators.
24
LASER #1 (VERTICAL) HIGH CURRENT WARNING – The laser in the vertical scanning
subsystem is drawing excessive current. This could be a warning for a future total failure. Have
the unit checked at an authorized service center when convenient.
25
LASER #2 (RIGHT HORIZONTAL) HIGH CURRENT WARNING – The laser in the vertical
scanning subsystem is drawing excessive current. This could be a warning for a future total
failure. Have the unit checked at an authorized service center when convenient.
26
LASER #3 (LEFT HORIZONTAL) HIGH CURRENT WARNING – The laser in the vertical scanning
subsystem is drawing excessive current. This could be a warning for a future total failure. Have
the unit checked at an authorized service center when convenient.
27
LASER #1 (VERTICAL) UNDERCURRENT WARNING – The laser in the vertical scanning
subsystem is drawing too little current. The laser is probably not on. This could be the result of a
loss of the required set point in memory. Have the unit checked at an authorized service center.
