1. Сlean scanner optical system.
2. Perform the following actions:
ADJ 3 Image density adjustment
3-A Copy mode image density adjustment
NOTE: This adjustment sets the copy density for each mode.
How to operate
When this adjustment is executed, the warm-up and the shading is performed. Then, the current setting value is displayed in 2-digits.
When the adjustment value is entered by the [Numeric] keys and press the [START] key, the setting value is saved and the machine
makes one copy.
When the setting value is increased, the printing copy becomes darker. When the setting value is decreased, the printing copy
becomes lighter. With this adjustment, only the Exp3 copy can be printed. If the setting value is increased, the Exp.1 and the Exp.5 copy also become darker. If the setting value is decreased, the Exp.1 and the Exp.5 copy also become lighter.
When the [INTERRUPT] key is pressed, the process is interrupted and the machine goes into the sub code input standby mode. When
the [CA] key is pressed, the simulation is terminated. The switching of each setting and display can be made with pressing the [AUTO/TEXT/PHOTO] key. The adjustment range is from 1 to 99.
  1. Set a test chart (UKOG-0162FCZZ) on the OC table as shown below.
  2. Put several sheets of A3 or 11" x 17" white paper on the test chart.
  3. Enter the SIM 46-2.
  4. After warm-up, shading is performed and the current set value of the density level is displayed on the display section in 2 digits.
    For mode selection, use the AUTO/TEXT/PHOTO key.
  5. Change the set value with the Numeric keys to adjust the copy image density.
  6. Make a copy and check that the specification below is satisfied.
|Density mode | LED | Exposure level | Sharp Gray Chart output |
|Auto | Auto| - | "2" is slightly copied.|
|Text | Text | 3 | "3" is slightly copied. |
|Photo (Error diffusion) | Photo | 3 | "2" is slightly copied. |
|Toner save | Auto/Photo | - | "2" is slightly copied |
|Toner save | Text/Photo | 3 | "3" is slightlycopied |
|Photo (Dither) | Auto/Text/Photo | 3 | "2" is slightly copied |
Set value:
The greater the set value is the greater the density is.
The smaller the set value is the smaller the density is.
