Registers A#5 and A#6 must be sent consecutively. Registers A#5, A#6, A#7, and A#8 must be
sent consecutively for different vertical/horizontal magnification.
*2
When both sides of documents are scanned and magnified in the sub-scanning direction, the
following limitations exist:
1)
B x (C/100) < 800
When a resolution exceeding 800 dpi is specified for scanning, an operation error occurs
(800 dpi is the maximum allowable resolution).
*3
When the vertical/horizontal zooming specification is set to "0", the horizontal and vertical
magnification is indicated. When this specification is set to "1", vertical magnification is
specified at bit 0 of the register #5 and at all bits of the register #6.
X'0864' is set when the power is turned on or when the initial status is specified.
Example
How to calculate the output resolution :
•
Control register #1 is X'0B' (200 dpi)
•
Image control register #5 and #6 are X'0819' (25%)
Output resolution = 200 dpi x 0.25 = 50 dpi
