AL-2030/2040CS/2050CS SIMULATION, TROUBLE CODES 10 - 20
46 20 SPF/RSPF exposure
correction
[Function]
Used to adjust the exposure correction amount in the SPF/RSPF mode. The adjustment is
made by adjusting Vref voltage variation for the OC mode.
When this simulation is executed, the current set value is displayed in 2 digits (Default: 50).
Change the set value and press [START] key to save the setting and make a copy.
When the set value is increased, copy becomes darker. When the set value is decreased, copy
becomes lighter. (Adjustment range: 1 – 99)
[Operation]
The operation is similar to simulation 46-01.
29 Image contrast adjustment
(600dpi)
[Function]
Contrast is set for each mode.
When this simulation is executed, the current se value is displayed in 2 digits (Default: 50).
Change the set value and press [START] key to make a copy under the set value.
When the set value is increased, the contrast becomes higher. When the set value is
decreased, the contrast becomes lower.
In this case, only Exp.3 copy is made. When, however, the setting is made to make higher con-
trast, Exp.1 and Exp.5 copies also become in higher contrast. When made to a lower contrast,
Exp1. and Exp.5 copies become lower contrast, too.
Press [Exposure mode selector] key (or [ ] [ ] key for the AL-2050CS) to switch the mode.
The set value of the selected mode is displayed on the LCD/display. (Adjustment value: 1 – 99)
* No density display on LCD/display.
[Operation]
The operation is similar to simulation 46-01.
30 AE limit adjustment [Function]
Used to set the limit value in AE and AE (toner save).
Change the setting and press [ENTER]/[START] key to write the setting into the EEPROM. The
machine goes into the sub code entry standby mode.
By pressing [Exposure mode selector] key (or [ ] [ ] key for the AL-2050CS), setting is
changed. (Setting range: 0 – 31, Default: 0)
<Remark>
When simulation 26-06 (Destination setting) or simulation 46-19 Auto Exposure mode is
changed, the setting of this simulation is also changed to the default in connection.
[Operation]
The operation is similar to simulation 46-19.
