It compares the sates of the originalsize sensors when the machine-side sensor goes ON and 3 sec thereafter toidentify the size of the original on the copyboard glass. If the user, there-fore, does not close the ADF within 3 sec after the machine-side sensorgoes ON, the GP605 (iR600) can wrongly identify the size as being A3.In the case of the machine, it uses 5 sec for the detection of original sizewithout affecting the first copy time (i.e., by making use of the 2 sec re-quired by the fluorescent lamp to go ON).90030 [3][4]
