Toshiba 452, 453, 350, 353 service manual Aps-C Aps-R, When the platen sensor is OFF

6

(4)Original size is determined by the combination of the signals output from each detection point. Combination charts for size determination of A4 series and LT series are as follows.

[A4 Series]

	Size judgement		APS-C		APS-R	APS-1	APS-2	APS-3
	A3		0		0	0	0	0
	A4		0		1	0	0	0
	B4		0		0	0	1	0
	B5		1		1	0	1	0
	A4-R		0		0	1	1	0
	A5		1		1	1	1	0
	B5-R		0		0	1	1	1
	A5-R		0		1	1	1	1
[LT Series]
	Size judgement		APS-C		APS-R	APS-2	APS-3
	LD		0		0	0	0
	LT		0		1	0	0
	LG		0		0	1	0
	LT-R		0		1	1	0
	ST		1		1	1	0
	ST-R		0		1	1	1
	Code	Output signal		Original
	1		H	Not available
	0		L	Available

* When the platen sensor is OFF,

•The followings are determined by output signals from the APS sensors. Size (The combination of the signals satisfy any in the above chart)

:Size is displayed on the control panel and a specific paper or reproduction ratio is selected.

Size retention (The combination of the signals do not satisfy the above chart)

:The latest original size recognized (or no original state) until new paper size is recognized. No original (Output from all the sensors are “H”.)

:Reproduction ratio and paper are not selected.

•Size change is always observed and detected.

•The carriage-1 stays at the standby position even if the reproduction ratio changes corresponding to the change of the original size.

*When the platen sensor is ON,

The latest original size (or no original state) recognized right before the platen sensor is turned ON is re- tained regardless of the status the APS sensor output signals.
