- Toner Agitation -
During a multiple copy job in 1C mode (Bk, C, M, and Y single-color copy
mode), the development unit does not rotate after the required color
development section has been rotated into position. This could result in a
false toner end detection because the toner is not carried from the main
hopper section [A] to the sub hopper section [B] during copying. To prevent
this from occuring, the development unit rotates at the following times.
1. Bk
In Bk & White mode, every 50 copies, even if it is during a continuous
copy job, the machine temporarily stops the copy job and the
development unit rotates once.
2. C, M, and Y
In C, M, or Y single-color copy mode, the development unit rotates once
every 50 copies (only for multiple copy jobs).
NOTE: When the timing of toner supply and toner agitation coincide, the
machine performs the operation that needs the most rotations.
