∗

The initial value for duplex setting is "1to2/Short Edge" for the OC/SPF setting, or "2to2" for the

SPF scan position automatic 
adjustment (SPF AUTO)

[Function]
Place a black chart so that it covers the SPF scan glass and the OC glass together, and close the OC
cover.

When this test command is executed, the current adjustment value is displayed as the initial display.

∗

Default is 1. Adjustment range is 1 – 99. Adjustment unit 1 = about 0.127mm

If the values are kept as the default values, SPF scan is not performed properly. The front area of
the proper scan position may be scanned.

In case of AUTO, press [START] key, and the mirror unit scans from the home position to the SPF
scan position with the adjustment value displayed. The SPF glass cover edge position is calculated
from the difference between the SPFG glass cover edge and the OC side document glass CCD out-
put level. If the adjustment is normal, the adjusted value is displayed. If abnormal, the error LED lights
up with the current set value displayed. 

During the error LED is lighted, when [START] key is pressed again, execution is performed again.
