• Explanation of status display
When the sensor test is carried out, the status
of each sensor is indicated on the display with
0 or 1.
Each signal is divided into 8-bit blocks.
The character on the left edge of the display
indicates as follows:
A: Signal input to ASIC
I: Signal input to the IO port
S: Signal from the scanner or R/ADF
P: Signal from the option connected to the
PFC
The display is switched using the
Example 1:
Confirm whether the front cover is open or close.
The front cover is equipped with the 24-V ON/OFF
switch (Interlock switch) and the front cover switch.
The status of both switches is 1 when the cover is
open, and 0 when it is close.
When the status of the one is 0 and that of the other
is 1 as shown in the example, there is something
wrong with either of these switches.
