APS Small Size Original Detection Chinese Paper Size Detection

Level Adjustment Flag

Selects whether or not the copier determines that the original is A5/HLT size when the APS sensor does not detect the size.

If "A5 length/5.5" x 8.5" is selected, paper sizes that cannot be detected by the APS sensors are regarded as A5 lengthwise or 5.5" x 8.5". If "Not detected" is selected, "Cannot detect original size" will be displayed.

Numbers 2 and 3 are used for Chinese paper sizes (267 x 390 mm and 195 x 267 mm). The meanings of numbers 2 and 3 are the same as for number 1 and 2. However, if the APS sensors detect the original, the machine assumes Chinese paper sizes.

For example: A4 ® 195 x 267 mm A3 ® 267 x 390 mm

Displays whether or not the standard white level adjustment has been done.
