1.6 Errors

COMMAND ERROR

[Cause] Unidentified command is detected.

[Disposition] The scanner sends NACK and waits for the next command. When the scanner

receives a wrong command or parameter, it disregards a value and maintains the former value.

[Indicator] READY LED lights up.

ERROR LED lights up.

[Remedy] The error condition is cleared when the scanner receives a correct command.

INTERFACE ERROR

[Cause] Wrong operation in the communication procedure is detected.

In case of SCSI, a time-out error occurred.

[Disposition] The lamp goes off and the operation stops.

[Indicator] READY LED goes off.

ERROR LED blinks.

[Indicator] READY LED blinks.

ERROR LED blinks.

[Remedy] Turn the scanner off and then back on.

Send Initialize command code (ESC @) to the scanner. Complete BUS DEVICE RESET message in SCSI. The RESET signal of SCSI is asserted.

[Acceptable commands] ESC F, ESC f, ESC @, FS F

OPTION ERROR (In Case Option Unit is Installed)

[Cause] Unit cover is open.

Paper empty condition

[Disposition] The bit7 of the status byte is set.

[Indicator] READY LED goes off.

ERROR LED goes off.

[Remedy] Remove the cause of the error condition.

[Remedy] Turn the scanner off and then back on.

The RESET signal of SCSI is asserted.

[Acceptable commands] None

FATAL ERROR

[Cause] The lamp is broken.

Power is turned on before removing the transportation lever. System breakdown.

[Disposition] The lamp goes off and the operation stops.

The bit 7 of the status byte is set.
