Leading edge detection
error
None

Input parameter error
(main scanning width
adjustment error)
Incorrect input of main scanning width
adjustment data (The input data is
outside the specified ranges 0 to 300,
9000 to 9300.)
Incorrect input of the main scanning length adjustment data.
1. Adjust the input data, and execute the "main scanning
width adjustment".
None
1521
Main scanning width
adjustment error
The main scanning width adjustment data
exceeded the specified range. (The main
scanning width adjustment data (N
counter value) is outside the specified
range 1900 to 2100.)
1. Adjust the input data, and execute the "main scanning
width adjustment".
None
1522
Input parameter error
(Scanning position
adjustment error) Incorrect input of the scanning position
is outside the specified ranges 0 to 120,
9000 to 9120.) Incorrect input of the starting position adjustment data.
1. Adjust the input data, and execute the "scanning position
adjustment".
None
1523
Scanning position
adjustment error
The adjustment data of the scanning
position exceeded the specified range.
(The starting position is outside the
specified range 76 to 266.)
·Incorrect measurement/calculation of
the main scanning image position
1. Adjust the input data, and execute the "scanning position
adjustment".
None
1530
Minimum density data
error
Incorrect data measurement/input.
1. Re-input the 24-point data. Execute correction.
2. Check for film defects (fogging, etc.)
3. Check the heat development unit.
4. Check the optical unit.
5. Replace the SCN board.
None
The leading edge detection signal is not
generated.
·Malfunction of the leading edge
detection sensor
·Malfunction of the optical unit (The
laser beam does not enter the leading
edge detection sensor)
·Faulty mounting of the optical unit to
the sub scanning unit.
·Film or foreign particle exists on the
leading edge detection sensor
·Faulty cable connection
·Malfunction of the SCN board
1. Check the cable connection.
2. Check if film or foreign particle exists on the leading edge
detection sensor.
3. Check the mounting of the optical unit to the sub scanning
unit.
4. Check the optical unit.
5. Replace the leading edge detection sensor.
6. Replace the SCN board.
The minimum density of the 24-point
density data exceeded the specified
value. (The minimum density is greater
than the specified value 400.)
·Film defects (Fogging, etc.)
·Malfunction of heat development unit
·Malfunction of the optical unit
·Malfunction of the SCN board
