Copier 

When the Copy key was pressed after placing the original on the document feeder, the 
copy key command would be processed first before the processing to determine the 
paper size on the document feeder, and as the result of it, the original was scanned from 
the document glass, which might cause the "blank page" output.  This problem has been 
corrected.

Scanner 

As the countermeasure for the lines when scanning the data from the document feeder, 
we have added the mode to search the most uncontaminated scan position on start-up 
(when power ON) and also on completion of scanning the job from the document feeder 
to the Soft SW so that it becomes possible to scan from the most uncontaminated scan 
position from the next scanning of the job from the document feeder.

Toner 
Replenishment 
Control 

There were some cases where "F2-6x" trouble was caused when the toner could not be 
replenished within a set time due to the imbalance of the toner etc.  For the 
countermeasures of this problem, the modification has been made to prevent from the 
false determination of "F2-6x" by performing the toner replenishment operation again 
when the machine detects that the toner dispense rate is not enough.
