ROM Version Upgrade from Ver. 3.5 to Ver. 3.7.

Description Cause Action

In cases where B5 sized copy paper has been selected and a B4 sized original document has been set (no detection) in machines bound for DPCM Japanese domestic market destinations, the starting position of the second page scanning operations is set so that copy operations are started from the scanning position of an A4 sized document (the copy operations should in fact be started from the B5 scanning position).

The settings of machines without original document detection in Japanese dpmestic market destinations were set so that A4 sized scanning operations were carried out regardless of the copy operation conditions, even if B5 sized copy paper was selected.

A change has been carried out so that in cases where the size of the original document cannot be detected in machines bound for DPCM Japanese domestic market destinations and B5 sized copy paper has been selected, the size of the original document which has been set is estimated from the copy paper size and the magnification settings, after which the scanning length is set for the scanning operations.

SMF action carried out as a measure to alleviate problems of fusing H4 trouble.

Due to the fact that the cause was undetermined, temporary action has been carried out.

H4 trouble is cleared by Sim 14 only in cases where the H4 trouble occurs twice during warm-up operations. A change has been carried out so that in other cases, H4 trouble is cleared by turning the power supply from OFF to ON.
