SETTING / ADJUSTMENT
6 - 14
[B] Reproduction ratio of secondary scanning direction (Fine adjustment of transfer belt motor
rotation speed)
*: This code is valid for 45/50ppm only.
If the sub code “0” of 05-4526 is adjusted, the adjustment values of sub code 4 and 9 is also changed
automatically, being operated with the adjusted value, according to the proper parameter.
[B-1] Confirmation of 05-4526-0
1. While pressing [0] and [5] simultaneously, turn the power ON.
→
(Adjustment Mode)
2. Press [98]
→
[FAX]. (A grid pattern with 10 mm pitch is printed out. Use A3/LD from the 2nd
drawer.)
3. Measure the distance B from the 2nd line at the leading edge of the paper to the 22nd line of
the grid pattern.
* Normally, the 1st line of the grid pattern is not printed.
4. Check if the distance B is within 200±0.5 mm.
5. If not, perform the procedure in “[B-2] Adjustment of 05-4526-0” to change the values and
measure the distance B again.
6. Perform the color registration (4719) after the adjustment.

* When the value is not within the recommended values, the trailing edge area of the image
may be out of position for the paper length or the density at the trailing edge area of the image
may become lower. Perform the adjustment confirming the image.

* The larger the adjustment value is, the longer the distance B becomes (approx. 0.1 mm/
step).

Notes:
• The grid pattern output by pressing [0][5]
→
[98]
→
[FAX] is the one of PRT (05-4526-0). Even if
the sub code 4 and 9 are adjusted, the result cannot be confirmed in the grid pattern output by
pressing [0][5]
→
[98]
→
[FAX].
• When “05-4526-0” is performed, a proper value is automatically calculated for the size of an
image in each function mode (copy/printer/Fax) or at each speed (normal speed/reduced speed/
high speed). The speed of the transfer belt motor is also adjusted. Therefore, use the above
default value other than the sub code “0,” unless otherwise required.
Remarks:
For A3/LD, it is recommended to adjust the distance B above within the range of 199.5 mm and
200 mm otherwise the margin of the trailing edge may be deleted.
Code Sub code Function Remarks
4526 0 PRT/PPC (Normal speed) When the value increases, the
reproduction ratio in the secondary
scanning direction becomes larger.
(Approx. 0.1 mm/1steps)
4 PRT/PPC (Reduced speed)
9 * PRT/PPC (Speed at low
temperatures)
