AL-1551 SIMULATION, TROUBLE CODES 10-10
48 01 Front/rear scan direction
(Outline)
(1) Front/rear scanning direction magnification ratio auto correction: (Performed by changing the set value of ZOOM DATA register for
ASIC.) The width of the reference line marked on the shading correction plate is scanned to perform the front/rear direction
magnification ratio adjustment automatically. (Performed by changing the set value of ZOOM DATA register for ASIC.)
(2) Front/rear scanning direction magnification ratio manual correction: Used to set the front/rear (main scanning) direction magnification
ratio by key operations. (Performed by changing the set value of ZOOM DATA register for ASIC.)
(3) Scanning direction magnification ratio correction: The scanning direction magnification ratio in the OC mode is set by key operations.
(Performed by changing the scanning speed.)
(4) SPF mode scanning direction magnification ratio correction: The scanning direction magnification ratio in the OC mode is set by key
operations. (Performed by changing the scanning speed.)
(Operation/Procedure)
1. When this simulation is executed, the current set value is displayed in two digits. (Center value: 50)
2. When the copy mode select key is pressed, the setting mode and the setting display are changed sequentially.
*The selected adjustment mode is indicated by the lamps as follows:
3. In the front/rear scanning direction adjustment, when the START key is pressed, the mirror base unit moves to the white plate for
shading and the width of the reference line is read and the correction value is calculated and displayed and the value is stored.
In the case of the manual adjustment, enter the adjustment value with the 10-key and press the START key.
Then the entered value is stored and a copy is made. (An increase of 1 in the set value corresponds to an increase of 1&.)
4. Press the clear key to store the set value and exit the simulation.
In the front-rear direction magnification ratio correction:
(1) The result of calculation of the scan correction value is
±
5% or less, "- -" is displayed.
(Cause) The white plate reference position error or the lens unit installing error
(2) In case of a scanning error of the reference line, the JAM lamp is turned on.
(Cause) CCD error or no white plate
* If the automatic correction of magnification ratio does not work properly, adjust and correct manually.
