2.3.4 PAGE SEPARATION AND DATA REDUCTION

Incoming pages that are only slightly longer than the copy paper may be reduced
in the sub-scan direction. Whether or not this happens depends on the settings of
printer switches 04 and 05.
Reduction Enabled
If bit 0 of printer switch 03 is at 1 (Enabled), the data will be reduced in the page
memory to fit on the copy paper. However, data will only be reduced if the length of
the incoming page is ± 5 mm shorter than a certain maximum length. The
maximum reducible incoming page length depends on the copy paper size and the
reduction ratio stored for that paper size in printer switches 04 and 05.
Each paper size can be programmed with a separate reduction ratio. In each of the
two bit switches, there is one bit for each possible paper size. The combination of
the bit settings determines the ratio for that paper size.

Incoming pages that are longer than the maximum length will not be reduced, but
will print on two pages and be treated in accordance with the setting of bit 1 of
printer switch 00. If this bit is 1, the bottom few lines of the page will continue from
where the first page left off. If it is 0, the next page continues from where the
previous page left off.
