Use it to enable/disable power on idle rotation of the color developing assembly (YMC).
Use it to adjust the intervals of patch ATR for the No. 1 limit. A higher limit will increase
the execution intervals, but will affect the density. On the other hand, although a lower
limit will decrease the intervals, the density will be more stable.
1. the number of prints (CNT) reset upon execution of patch detection
2. cumulative video count CNT)
Timing
1. execute patch detection during last rotation of the ongoing job when the No. 1 limit
(20 prints) is exceeded.
2. force patch detection by interrupting the job as soon as the No. 2 limit is exceeded.
3. force patch execution as soon as the cumulative VC exceeds 300% (in terms of A4).
1 print = 3 images (YMC only); for image count, 1 for small and 2 for large)
The new setting will not be valid until the power switch has been turned off and then on.
0: off
1: on
at time of shipment/upon RAM initialization: 1
Use it to change the intervals of 1 patch detection (No. 1 limit) in terms of the number of prints.
Use it to change the intervals of patch ATR for the No. 1 limit. A higher limit will increase the
downtime intervals, but will affect the density. On the other hand, although a lower limit may
decrease the downtime intervals, the density will be more stable.
The following triggers are used to initiate patch detection:
1. when the 1st limit (20 prints) is exceeded, execute patch detection during the last rotation of
the ongoing job.
2. when the 2nd limit is exceed, stop the ongoing job and force patch detection.
(1 print = 3 images (YMC only); for image count, 1 for small and 2 for large)
The above No. 1 limit may be changes. A higher limit will increase downtime intervals, but will
affect density. On the other hand, although a lower limit will decrease downtime intervals, the
density will be more stable.
By default, the No. 1 limit is 20 prints (60 images), variable between 10 and + 10 (offset).
The new setting will not be valid until the power switch has been turned off and then on.
10 to +10
