How to adjust
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 the Dip switch to 8, (on).
3 • Turn on the PC or Mac and scanner and access the service program
main menu (section 3•5).
4 • Mount a piece of transparent tape onto the zero corner of the drum
and draw two vertical and two horizontal lines on the tape.
Note: if the horizontal line on the monitor cannot be seen, the lines
give an idea of how much to adjust the micro switch if the zero
point is not correct.
5 • Select W, (Turn on SCSI in switch seek mode) to override the step
count function and enable SCSI mode.
6 • Access Photoshop plug-in and hold the D key down.
7 • Cancel the LD, (Leave drum) function in plug-in.
8 • Make a preview in the zero corner (10 x 10 mm approximately).
9 • The horizontal line on the monitor (short line), should be visible in
the zero position as shown in fig. 1.
Note: The horizontal and vertical lines on the drum need not be
shown in full width; half the width of the lines is sufficient.
10 • If incorrect and access is not already available, remove the follow-
ing panels:
Right hand end plate C and right hand drum cover D, (section 4•2
steps 3 and 4).
11 • Locate the two holes on the top right hand side of the scanner,
(fig. 2) and loosen the two 3 mm allen screws A securing the micro-
switch bracket to the frame and adjust as necessary.
12 • Repeat steps 8 and 9.
13 • Carry out a white calibration in transmission (section 5•5).
14 • If no further adjustment or replacement operations are required,
refit covers C and D, (section 4•2).
