Adjustment. B. Image position
There are following five 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, 50-06 and 50-10 are used.
| No. | Adjustment item | Simulation |
|---|---|---|
| 1 | Print start position (Main cassette paper feed) | 50 - 01 |
| 2 | Print start position (2nd cassette paper feed) | 50 - 01 |
| 3 | Print start position (Manual paper feed) | 50 - 01 |
| 4 | Image lead edge void amount | 50 - 01 |
| 5 | Image scan start position | 50 - 01 |
| 6 | Image rear edge void amount (Main cassette paper feed) | 50 - 01 |
| 7 | Image rear edge void amount (Manual paper feed) | 50 - 01 |
| 8 | Front surface document scan position | 50 - 06 |
| 9 | Rear edge void amount (ADF) | 50 - 06 |
| 10 | Center offset | 50 - 10 |
To select the adjustment mode with SIM 50-01, use the copy mode select key. The relationship between the adjustment modes and the lighting lamps are as shown in the table below.
| Adjustment mode | Lamp ON |
|---|---|
| Print start position (Main cassette paper feed) | AE, main cassette lamp |
| Print start position (2nd cassette paper feed) | AE, 2nd cassette lamp |
| * Print start position (Manual paper feed) | AE, manual paper feed lamp |
| Image lead edge void amount | AE, main cassette lamp |
| Image scan start position | PHOTO, main cassette lamp |
| Image rear edge void amount (Main cassette paper feed) | AE, TEXT, PHOTO, main cassette lamp |
| Image rear edge void amount (Manual paper feed) | AE, TEXT, manual paper feed lamp |
*: Supported for the installing model and skipped for non-installing mode
To select the adjustment mode with SIM 50-10, use the copy mode select key. The relationship between the adjustment modes and the lighting lamps are as shown in the table below.
Machine with the multi manual paper feed unit
| Adjustment mode | Lamp ON |
|---|---|
| Print center offset (Main cassette paper feed) | AE, main cassette lamp |
| * Print center offset (2nd cassette paper feed) | AE, 2nd cassette lamp |
| Print center offset (Manual paper feed) | AE, manual paper feed lamp |
| * Second side center offset (Main cassette paper feed) | TEXT, main cassette lamp |
*: Supported for the installing model and skipped for non-installing mode.
(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, main cassette lamp ON) (A), the lead edge void amount (TEXT, main cassette lamp ON) (B), and the scan start position (PHOTO, main cassette lamp ON) (C) to 0, and make a copy of a scale at 100%.
- Measure the image loss amount (R mm) of the scale image. Set C = 10 X R (mm). (Example: Set the value of C to 30.) When the value of C is increased by 10, the image loss is decreased by 1mm. (Default: 50)
- Measure the distance (H mm) between the paper lead edge and the image print start position. Set A = 10 X H (mm). (Example: Set the value of A to 50.) When the value of A is increased by 10, the image lead edge is shifted to the paper lead edge by 1mm. (Default: 50)
- Set the lead edge void amount to B = 50 (2.5mm). When the value of B is increased by 10, the void amount is increased by about 1mm. For 25 or less, however, the void amount becomes zero. (Default: 50)
(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.
(3) Center offset adjustment
- Set the self-made test chart for the center position adjustment so that its center line is aligned with the center mark of the document guide.
• Test chart for the center position adjustment. Draw a line at the center of A4 or 8-1/2" x 11" paper in the paper transport direction. - Execute SIM 50-10 to select the print center offset (cassette paper feed) adjustment mode. The set adjustment value is displayed on the copy quantity display.
- Make a copy and check that the copied center line is properly positioned. The standard value is 0 ± 2mm from the paper center.
- If the measured value is out of the specified range, change the set value and repeat the adjustment procedure. When the set value is increased by 1, the copy image is shifted by 0.1mm toward the rear frame.
• For the manual paper feed, change the manual paper feed adjustment mode and perform the similar procedures.
• Since the document center offset is automatically adjusted by the CCD which scan the reference lines (F/R) on the back of document guide, there is no need to adjust manually.
