Adjustment. 1B Image position adjustment
There are following eleven kinds of image position adjustments, which are made by laser control except for the image scan start position adjustment. For the adjustments, SIM 50-01 and 50-10 are used.
| No. | Mode | SIM |
|---|---|---|
| 1 | Print start position (Main cassette paper feed) | 50-01 |
| 2 | Print start position (Manual paper feed) | 50-01 |
| 3 | Image lead edge void amount | 50-01 |
| 4 | Image scan start position | 50-01 |
| 5 | Image rear edge void amount (Cassette paper feed) | 50-01 |
| 6 | Image rear edge void amount (Manual paper feed) | 50-01 |
| 7 | Print center offset (Main cassette paper feed) | 50-10 |
| 8 | Print center offset (Manual paper feed) | 50-10 |
To select the adjustment mode with SIM 50-01, use the ◄ ► key.
The relationship between the adjustment modes and the lighting lamps are as shown in the table below.
| Adjustment mode | Display item | Lamp ON |
|---|---|---|
| Print start position (Main cassette paper feed) | TRAY1 | COPY mode lamp Main cassette lamp |
| Print start position (Manual paper feed) | MFT | COPY mode lamp Manual paper feed lamp |
| Image lead edge void amount | DEN-A | PRINT mode lamp Main cassette lamp |
| Image scan start position | RRC-A | SCAN mode lamp Main cassette lamp |
| Image rear edge void amount (Cassette paper feed) | DEN-B | COPY mode lamp PRINT mode lamp SCAN mode lamp Main cassette lamp |
| Image rear edge void amount (Manual paper feed) | RRC-B | COPY mode lamp PRINT mode lamp Manual paper feed lamp |
To select the adjustment mode with SIM 50-10, use the ◄ ► key.
The relationship between the adjustment modes and the lighting lamps are as shown in the table below.
| Adjustment mode | Display item | Lamp ON |
|---|---|---|
| Print center offset (Main cassette paper feed) | TRAY1 | COPY mode lamp Main cassette lamp |
| Print center offset (Manual paper feed) | MFT | COPY mode lamp Manual paper feed lamp |

1 Lead edge adjustment
- Set a scale to the center of the paper lead edge guide as shown below, and cover it with B4 or 8 1/2" x 14" paper.
- Execute SIM 50-01
- Set the print start position (AE mode lamp/COPY mode lamp ON) (A), the lead edge void amount (TEXT mode lamp/PRINT mode lamp ON) (B), and the scan start position (PHOTO mode lamp/SCAN mode lamp ON) (C) to 0, and make a copy of a scale at 100%.
- Measure the image loss (Rmm) of the scale. Set C = 10 x R (mm). (Example: Set to 40.) When the value of C is increased by 10, the image loss is decreased by 1mm. (Default: 50)
- Measure the distance (Hmm) from the paper lead edge to the image print start position. Set A = 10 x H (mm). (Example: Set to 50.) When the value of A is increased by 10, the image lead edge is moved to the paper lead edge by 1mm. (Default: 50).
- Set the lead edge void amount to B = 50 (2.5mm). (Default: 50) When the value of B is increased by 10, the void is extended by about 0.1mm. (For 25 or less, however, the void amount is regarded as 0.)
* The RSPF adjustment is made by adjusting the RSPF image scan start position after OC adjustment.
2 Image rear edge void amount adjustment
- Set a scale to the rear edge section of A4 or 11" x 8 1/2" paper size as shown in the figure below, and cover it with B4 or 8 1/2" x 14" paper.
- Execute SIM 50-01 to select the image rear edge void amount adjustment mode. The set adjustment value is displayed on the copy quantity display.
- Make a copy and measure the void amount of image rear edge.
- If the measurement value is out of the specified range, change the set value and repeat the adjustment procedure. The default value is 50.
Note:
The rear edge void cannot be checked with the first sheet after entering the simulation mode, the first sheet after turning off/on the power, or the first sheet after inserting the cassette. Use the second or later sheet to check the rear edge void.
