TonerEndJudg
This SP code determines whether the machine disables printing when the
machine detects toner end.
Even when toner end is detected, there is a small amount of toner left in
the AIO. If a user wants to print with the AIO until all toner is used up,

then set this SP to 1. But then, there is no toner end detection, and the
user must watch the print quality and change the AIO when prints
become too pale.
[0 to 1/0/1]
0: Yes (Printing stops when toner end is detected.)
1: No (Printing can continue even after toner end is detected.)
