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 WARNINGThe 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.
