Interaction
The Focus adjustment has a big influence on the Scan-Width adjustment. Therefore the ScanWidth must be checked and readjusted if necessary when the Focus adjustment has been
changed.
When all camera adjustments have been completed, run Scanner Maintenance.
4.2.3 Check and Adjustment of Scan Width
Images of Scan-Width adjustments are shown in:
Fig. 4-5 ACS 4600, Focus Signal and Scan-Width, page 56.
The aim of this adjustment is to obtain a Scan-Width of 31.9637 mm.
The Scan Width is correct if the total sum of Scan-Width Units (SWU) at the start and the end
of the scanline is 14 (1 SWU is either 1 Black Line or 1 White Space of the Scan-Width
Pattern on the Camera Adjustment Card).
Adjustment Procedure
Always perform the Focus adjustment before adjusting the Scan-Width, see “Interaction”
below.
Open the Reject Tray and pull out the card stop.
