3.2 Detail Codes for Scanner Errors
Scanner errors are detected by checking a plurality of scanner I/O states and finding a
combination of defects and/or failures.
Each I/O status at the time of error occurrence can be identified by checking the detail
code in the error log.
n
Display of Detail Code
The detail code is displayed in six hexadecimal digits, located in the error log as
shown below.
n
Meaning of Six-Digit Detail Code
To each bit of a six-digit detail code is assigned an object to be checked during error
check, so that a bit value of “1” indicates that the object to checked is in error.
NO. Object to be checked Signal source
