Reason for

To improve RDH operation

Modification

If more than 64 original sheets are set, the RDH will not be able to count the originals properly. ( NOTE 1)
As the result:

1. The front side of copy will be blank when the " 1 side to 2 sided copy " mode is selected.

2. The jam auto-recovery will not operate, even if a jam occurs.

To prevent these occurrence, all copy operations stop when the RDH counts 64 original sheets.
