How to adjust
Note : Focus calibration should be performed before white point
calibration if possible.
1 • Fit a terminator to a SCSI connector on the scanner and SCSI cable
and RS 232 service cable to the scanner and PC.
2 • Set theDip switch to 8, (on).
3 • Turn on the Mac or PC and access the service program main menu
(section 3•5).
4 • Select S, (Turn on SCSI).
5 • Access Photoshop plug-in.
6 • Mount the auto focus adjustment target on the drum as follows:
For Transmission calibration, mount the target on a clear
area of the drum.
For Reflection calibration, first mount the target on a piece
of clean, white paper of about the same thickness and white-
ness as the originals that are normally scanned and then
mount the paper on the drum.
7 • Make a preview scan of the target, selecting transmission or reflect-
ion as applicable.
8 • Crop a square of approximately 20 x 20 mm (1” x 1”) in the center of
the target.
9 • If the drum is not bar-coded, click on Options to open the Focus &
Aperture dialogue. Choose the desired drum number from the Drum
menu and click on OK.
Note: this step is not necessary if the drum has a bar code.
10 • For Macintosh, hold down the command key so that the Preview
button in the plug-in window changes to Focus, and click on Focus.
11 • For PC’s, double-click on the Calibrate box in the plug-in window so
that the Preview button changes to Cal. Focus. Click on Cal. Focus or
press enter.
Note: the focus calibration will be stored permanently with the bar
code number in the memory of the scanner - only on Scanmate 5000,
(0210 model).
