(4) RSPF image lead edge position adjustment
1) Set a scale on the OC table as shown below.
3) Check that the lead edge is not shifted. (Both surfaces) (If the precedent lead edge adjustment was complete, the lead edge follows automatically after changing the scan position.)
Place no other things than the black chart on the glass.
Note: Since the printed paper is used as the test chart, place the scale in parallel to the front edge of the copy glass.
For the SPF standard machine, check that the SPF glass is covered completely by the black chart.
2) Make a copy, and use the copied paper as the document and make a copy from RSPF again. 3) Check the copied paper. If an adjustment is required, perform the following procedures. 4) Execute SIM 50-6. 5) Set the RSPF lead edge position set value so that the image similar to the adjusted image at the OC image lead edge position described previously is printed. <Adjustment specifications> Adjustment mode Image lead edge position SIM Set value Specification Set range 1 ~ 99
SIM 50-6 1step: 0.1mm shift Lead edge void: 1 ~ 4mm Image loss: 3mm or less
(5) SPF scan position automatic adjustment
The SPF scan position is automatically adjusted. 1) With the SPF or the OC cover open, place a black background chart on the OC glass. (The SPF standard model includes the SPF glass surface.) * Use a black chart UKOG-0011QSZZ, or make a chart as shown below and use it. Chart size: 310 x 470 Use a cutting sheet No. 791 (Black) or an equivalent for making a chart. Reason: To protect against erroneous detection caused by disturbed lights of fluorescent lamps, etc.
How to place the black chart Cover this area.
2) Enter SIM 53-08, and press the COPY button. Outline of SIM: The optical unit is moved to recognize the boundary between the OS glass and the SPF glass. The SPF scan position is automatically adjusted with the boundary position as the reference. Caution: � After completion of the SPF scan position automatic adjustment, perform the SPF lead edge adjustment (both surfaces). � Place no other things than the black chart on the glass. � Since SPF scan is made around the center in the main scanning direction, take care not to allow external lights to enter the section.
