AL-1551 SIMULATION, TROUBLE CODES 10-9

46 01 Copy density adjustment

(Outline)

Used to adjust the copy density in each copy mode. (The copy density can be set by changing the set value of ASIC GAMMA ADJUST

Setting in each copy mode is performed at exposure level 3. When the copy density (exposure) is adjusted arbitrarily, the max, and min.

exposure levels are automatically calculated and set. (The change amounts (gradient, change amount) at level 1 - 5 are predetermined.)

(Operation/Procedure)

1. When this simulation is executed, warming up and shading are performed and the current set value is displayed in two digits.

2. Press the copy mode select key to select each setting mode and setting display.

*The copy mode setting is indicated with the following lamps as shown below.

3. Change the setting with the value up-down key and press the START key, and a copy will be made with the entered set value.

4. Press the clear key to store the set value and exit the simulation.

Relationship between the displayed values and the GAMMA ADJUST register

The value displayed after execution of this simulation can be set in the range of 0 - 99 with 50 as the center value.

When the text mode set value is Gat3, for example, the GAMMA ADJUST register value set at Exp1 is:

Text Exp1 = Gat3 - 50 - 24

When 40 is set to Gat3, Text Exp1 = 40 - 50 - 24 = -34.

Then set the GAMMA ADJUST register set value to -34.

Perform the same procedure for each mode and each Exp.

*The above table may subject to change.

*For the gradient, there is a similar table, though not specified here. The value set with SIM 46, however, is not reflected.

*The AE mode Exp selection is not specified, but corresponds to the grades for AE exposure selection in the former models.
