2.4Recording paper selection algorithm and print algorithm

2.4.1Recording paper selection algorithm

Capable of identifying the above-mentioned recording paper size of a received image, this machine prints on the recording paper of the same size as when sent, as a rule. If no recording paper of the iden- tified size is not available, it selects recording paper for printing according to the set mode. The mode is set by using Func. 15 bit 3.

1)Automatic reduction mode (Func. 15 bit 3 = 0, Default)

Selects recording paper on which the received document can be printed and prints on it.

2)Reduction OFF mode (Func. 15 bit 3 = 1)

Selects recording paper on which the received document can be printed in a full size.

2.4.2Print algorithm

A reception print image is basically printed on one page. Consequently, the algorithm of reception print is in the order of same size print, discard extra, vertical reduction print, and divided print. (Refer to the reception print flowchart.)
