The original cover is closed (at an angle of 5 deg or less)The original size is identified.Original sensor: Turns off.In identifying the original size, the data obtained in the original size identification process 1 is compared with the data obtainedin the original size identification process 2 to check whether these two pieces of data are identical.Note that a wrong original size may be identified because the sensor output level does not change in the following cases:• When the original is A3-sized black• When the original is a book (its thickness does not allow the copyboard cover to close fully, making it difficult to detect thesensor level change).• When the copyboard cover is not closed fully (the sensor level change is not detected after lapse of the above time-out time)Change absentChange presentOriginal sensor 1Original sensor 0Original (A4R)Original sensor 2AOriginal sensor 3Before original size identification processes 1 and 2 are performed, the original size is detected with original sensors as follows:AB-ConfigrationA3A4B4(8K)*1B5(16K)*1A4RB5R(16K)*1No originalOriginalsizeOriginalsensor 0Originalsensor 1Originalsensor 2AOriginalsensor 3Inch-Configration11"X17"LTRLGLLTR-RNo originalOriginalsizeOriginalsensor 0Originalsensor 2BOriginalsensor 3:No original:Change absent*1: For Chinese paper, the following sizes are detected:8K:Equivalent to B4 size16K:Equivalent to B5 size2.
