[Bit 0, 1]
Use a combination of bit 0 and bit 1 to set the size of paper (default side).
- if 0 and 0, A/B-configured paper.
- if 0 and 1, inch-configured paper
- if 1 and 0, A-configured paper
- if 1 and 1, A/B-configured paper
[Bit 2]
Use it to specify whether to convert an inch resolution into a metric resolution for images read at time of G3
transmission only in sub scanning direction or in both main and sub scanning direction.
The setting made here is effective only if bit 1 of SW05 of #1 SSSW is set to '1'.
[Bit 4]
Use it to specify whether or not to declare an inch resolution to the other party at time of G3 communication.
If set to '1' a declaration will be made using the DIS, DCS, or DTC signal to the effect that the machine is designed
to read and record images at an inch resolution.
MEMO:
The type of image and the direction of scanning for inch/meter resolution conversion are determined by combinations
of bits 1 and 2 of SW05 and bit 2 of SW14 of #1 SSSW as well as the type of dialing used.
