Sharp MXM160D

a. OC image lead edge position adjustment (SIM 50-1)

Note: In advance to this adjustment, the sub scanning magnification ratio adjustment must be performed.

1. Set a scale on the OC table as shown below.
2. Make a copy.
3. Check the copy output. If necessary, perform the following adjustment procedures.
4. Execute SIM 50-1.
5. Set the OC lead edge position set value (PHOTO indicator ON) to [1] The OC image scanning start position is shifted inside the document edge.
6. Set the 1st tray lead edge void adjustment value (TEXT indicator ON) * to [1] The lead edge void becomes the minimum.
7. Set the 1st tray print start position value (AUTO, 1st tray indicator ON) to [1] and make a copy. The print start position is shifted inside the document edge.
8. Measure the image loss R of the copied image. Enter the set value of the image scanning lead edge position (PHOTO indicator ON) again.
   • 1 step of the set value corresponds to about 0.1mm shift.
   • Calculate the set value from the formula below.
   R/0.1(mm) = Image loss set value
   <R: Image loss measurement value (mm)>
   Example:4/0.1 = 40 = about 40
   Note: If the set value is not obtained from the above formula, perform the fine adjustment.
9. Measure the distance H between the paper lead edge and the image print start position. Set the image print start position set value (AUTO, 1st tray indicator ON) again.
   • 1 step of the set value corresponds to about 0.1mm shift.
   • Calculate the set value from the formula below.
   H/0.1(mm) = Image print start position set value
   <H: Print start position measurement value (mm)>
   Example:5/0.1 = 50 = about 50
   Note: If the set value is not obtained from the above formula, perform the fine adjustment.
10. Set the lead edge void adjustment value (TEXT indicator ON)* again.
    • 1 step of the set value corresponds to about 0.1mm shift.
    • Calculate the set value from the formula below.
    B/0.05 (mm) = Lead edge void adjustment value
    <B: Lead edge void (mm)>
    Example:When setting the lead edge void to 2.5mm
    :2.5 /0.05 = about 50
    Note: If the set value is not obtained from the above formula, perform the fine adjustment.
    *2nd tray lead edge void adjustment: Exposure display <<AUTO + TEXT + PHOTO>> Bypass tray lead edge void adjustment: (TEXT indicator and PHOTO indicator ON)

Duplex mode adjustment

OC 2nd print surface (Auto duplex) lead edge position adjustment: SIM50-19 <<PHOTO>>
*For the adjustment procedure, set to S → D mode before execution.

Note:
Before performing the 2nd print surface lead edge position adjustment and the lead edge void adjustment, be sure to perform the 1st print surface lead edge position adjustment in advance, and be sure to perform the 2nd print surface lead edge position adjustment and then the lead edge void adjustment in this sequence.
