Toshiba e-Studio200 Pfc, Display is switched using the or key Status display example, IO4 Bit2

•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 or key.

Status display example

A	A1		A2		A3
I	IO1		IO2		IO3
	IO4		IO5		IO6
	IO7		IO8
	S	1	S	2
S
	S3		S4
P	P1		P2		P3
	P4		P5

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.

	Front cover
	Open	Close
IO3 bit 1 (Interlock switch)	1	0
IO4 bit 2 (Front cover switch)	1	0
