Significance/Occurrence Condition
During scanner self-diagnostics, a leading-edge detection
interrupt does not occur.
During scanner self-diagnostics, an end-of-screen interrupt
does not occur.
With initial HV voltage status check, an error is detected.
With polygon status check during read, an error is detected.
With laser power status check during read, insufficient power
is detected.
With laser power status check during read, an error is
detected.
With HV voltage status check during read, an error is
detected.
Analog power supply error is detected in the PMT08A board. Check and replace the PMT08A board.
With start-point detection status check during read, an error is
detected.
With leading-edge detection status check during read,
an error is detected.
Because an end-of-screen interrupt does not occur during
reading and thus a timeout occurs, reading is retried.
An overexposed IP is detected during read.
With status check during system shutdown after reading
error, an error is detected.
With status check after reading condition setup, an error is
detected.
With status check after reading condition setup, an error is
detected.
With status check during system shutdown after reading
error, an error is detected.

Detail: Denotes the detail information format.
Probable Cause/Remedy
Check and replace the IP leading-edge sensor
(SED08A).
Check and replace the SCN08A board, polygonal mirror
assembly, scanning optics unit, and SYN08A board.
Check and replace the PMT08A board.
(If no abnormal image results, it should be ignored.)
Check and replace the polygonal mirror assembly.
(If no abnormal image results, it should be ignored.)
Check and replace the light source unit.
(If no abnormal image results, it should be ignored.)
Check and replace the light source unit.
(If no abnormal image results, it should be ignored.)
Check and replace the PMT08A board.
(If no abnormal image results, it should be ignored.)
(If no abnormal image results, it should be ignored.)
Check and replace the SYN08A board.
(If no abnormal image results, it should be ignored.)
Check and replace the IP leading-edge sensor
(SED08A).
(If no abnormal image results, it should be ignored.)
Faulty SCN board, scanner hardware, etc.
It is because an IP was exposed under overexposure-
equivalent conditions.
Faulty SCN board, scanner hardware, etc.
