The image data for the scanner comes from the IPU chip on the BICU board in the
main machine through the MB board. Most image processing for the scanner is
performed in the IPU. However, gamma patterns and dither patterns which stored
in the RAM on the scanner board are used.
The 8-bit image data (in grayscale processing mode) from the IPU chip goes to the
selector, where the data is divided into two image data signals: odd-pixel data and
even-pixel data. This is to match the data transfer speed between the input data
(20 MHz – grayscale processing mode) and the process speed in the SBC chips
(10 MHz each). Then, some filters and patterns are used to process the data and
the data is merged in the multiplexer, then it goes to the PC through the SCSI
controller.
1-bit data (in binary picture processing mode) is not divided into two data signal
and it will be used only the SBC 1 chip.
The image data is stored in the memory buffer. The total memory size is 2 MB.
When the memory is full, the scanner stops scanning until the memory is empty.
Then the scanner starts scanning again.

SCANNER FUNCTIONS 26 February, 1999
2.3 SCANNER FUNCTIONS
2.3.1 SELF DIAGNOSTICS
Whenever t he main power switch is turned on the scanner board performs the self
diagnostics and the following items will be checked autom atically.
• SRAM read/write check
• Initializes the SBC ch ip
• Initializes the SCSI co ntroller
• Connection check between the scanner board and main machine
If an error is detected, an appropriate error message or condition will be generated
(refer to the Troubleshooting section).
2.3.2 ENTERING THE SCANNER MODE
There is no scanner function key on the operation panel. Instead of this, the
machine enters the scanner mode when the machine receives the scanner
command from a PC. However, the machine cannot enter the scanner mode in one
of the following conditions.
• Using the scanner or ADF (copying, scanning for facsimile transmission, etc)
• Interrupt copy mode
• In the UP or SP modes
• ADF jam or ADF cover open
• In Auto Off mode or Night mode
2.3.3 LEAVING THE SCANNER MODE
The machine leaves scanner mode when the system reset timer has run out or
when another function key (Copy or Fax or Printer) is pressed.
2.3.4 SCSI ID
The SCSI ID can be selected using UP mode (1. System – 21. Scanner SCSI ID).
The SCSI terminator is on the scanner controller board and it is always activated.
So, when installing the machine in the SCSI chain, this machine must be at the end
of the SCSI chain.

6. Insert the scanner kit [C] in the third slot from the right of the expansion box.
If the ISDN board has already been installed, do steps 7 to 9.
7. Slide out the ISDN board [D].
8. Thread the ISDN modular cable [E] through the opening [F] in the scanner
board, as shown.
9. Install the scanner board and ISDN board in the expansion box at the same
time.

screws)
11. Cut away the cover [C] from the left cover [D].
12. Reassemble the machine.
13. Attach the ferrite core [E] to the SCSI cable [F], as shown.
Then, turn the machine on.
14. Change the setting of Function Switch (User Tool - 1. System - 06. Function
Switch) to “Instant”.
15. Set the SCSI ID number (User Tool - 1. System - 21. Scanner SCSI ID). Then
turn the machine off and on to store the ID number.
NOTE:
1) Do not enter a SCSI ID number that is used by another SCSI device.
2) If the machine is connected to a SCSI chain, it must be connected as
the last device. (The terminator on the scanner board is fixed).

SELF-DIAGNOSTICS 26 February, 1999
4. TROUBLESHOOTING
4.1 SELF-DIAGNOSTICS
The scanner board automatically performs the self diagnostics whenever the main
power switch is turned on. If an error is detected, it displays the error message on
the LCD or it informs the error using an LED on the scanner board.
