Table 2-2
Reference:
1. When storing JPC (No. 9), adjust the guide width to the smallest width.
2. At time of shipment, the settings are A3, A4R, and JPC; the copier retains the
characteristics curves of the corresponding three points and uses them when
identifying the size of paper during copying operation. When you store a size other
than these three, the copier takes the new settings into account when making
computations; for this reason, it is best to store sizes that the user tends to use most
frequently.
