8. DISASSEMBLING AND ADJUSTING THE MECHANICAL PARTS
Reattaching the CIS power board
(1) Reattach the CIS power board in the reverse order in which it was detached.
(2) Check that the output voltage is 5.3V ±0.02V between the VR1 side of R17 and GND when you replace
the CIS power board.
How to check the output voltage
1. Disconnect the cables from J2 and from J10 to J15.
2. Turn on the power. (Connect the power cable to the scanner power inlet.)
3. Measure the output voltage between the VR1 side of R17 and GND.
4. If the output voltage is not 5.3V ±0.02V, adjust the voltage using VR1 on the CIS power board.

How to find out type of the CIS power boards
There are two kinds of the CIS power boards, which is used to SK200-09 or SK200-09-A.
So prepare corresponded CIS power boards before replacing the CIS power boards.
The model name label is showing the type of the CIS power boards.
If the model name is SK200-09 use the old type of the CIS power boards.
If the model name is SK200-09-A use the new type of the CIS power boards.
