The motor driver on the interface PCB controls the rotation (activation/deactivation) of the scanner motor and its direction and speed of rotation according to the
signals from the CPU.

- Moving the Scanner in Reverse After an Image Scan
After an image scan, the No. 1 mirror base is moved in reverse to shading position at 234 mm/sec regardless of the selected color mode.
- Moving the Scanner Forward for an Image Scan
When making an image scan, the No. 1 mirror base unit is moved by controlling the motor as follows:
F-5-14
The machine uses the following scanning speeds to suit different modes;
T-5-5
5.3.2 Enlargement/Reduction
5.3.2.1 Changing the Magnification in Main Scanning Direction
0012-9674
imagePRESS C1 / Color Image Reader-H1 / imagePRESS C1+ (Printer) / imagePRESS C1+
For main scanning direction in both copyboard and ADF modes, the image is read at 100%, and the magnification is varied by the main controller block.
5.3.2.2 Changing the Magnification in Sub Scanning Direction
0012-9675
imagePRESS C1 / Color Image Reader-H1 / imagePRESS C1+ (Printer) / imagePRESS C1+
For sub scanning direction in both copyboard and ADF modes, the image is read at 100%, and the magnification is changed by the main controller block.
In SEND mode, the reading size is switched between 100% and 50% depending on the selected resolution.
5.3.3 Controlling the Scanning Lamp

The scanning lamp is controlled for the following, with associated control mechanisms operating as follows:
1. Turning On and Off the Scanning Lamp
The scanning lamp is turned on or off by the drive signal (XE-ON) generated by the CPU of the reader controller PCB. When the signal is generated, the inverter

1. Acceleration Zone: accelerates to suit the selected mode
2. Approach Zone: moves for speed stabilization.
3. Image Read Zone: reads the image at a specific speed.
(if black-and-white/SEND mode, twice as fast as in full-color mode)
4. Deceleration Zone: past the image trailing edge, immediately decelerates and stops.
