CHAPTER 18: APPENDIX
RISO i Quality System
With the RF-tag on the master roll and ink bottle, the machine is designed to give best performance for
each operating condition in real time.
Listed below are the major performance feature of the RISO i Quality System.
1) Printing Density Control
Depending on the condition of the machine, the printing speed is controlled before the selected
printing speed is achieved.
This is to produce solid image prints with less wasted printing papers.
2) Drum Idling Control
Depending on the working condition, the condition of the ink in the Drum differs. To give best print
outs, the number of Drum rotation during the Drum idling action is changed to produce solid image
prints with less wasted printing papers.
3) Thermal Power Control on TPH
The TPH thermal power is controlled to match with each master roll and its condition.
4) Elongation and Shrinkage Control in Master Making
Depending on the amount of mater material remaining on the master roll, the speed of the Write pulse
motor is controlled to reduce the image elongation and shrinkage in master making.
5) Ink and Master Remaining Amount Display is Controlled
More precise information is given on the operation panel of the machine on the remaining amount of
the ink and master to the operator.
6) Inkless Timer Control
Depending on the amount of ink left in the ink bottle, the inkless timer is controlled before displaying
the ink bottle replacement panel message to reduce the false replacement message display. The
same control is used also to prevent pumping in excess air into the Drum when the ink amount left in
the ink bottle is close to empty.
7) Additional Information on the RISO i Quality System
In the case when adequate information is not achieved from the RF-tag, the machine panel message
indicates [H01-566] for the ink and [H04-242] for the master.
If these [H] displays are indicated, input the necessary parameter setting to continue the printing or
master-making operation.
[H01-566] Input either 1 (black ink) or 2 (color ink)
[H04-242] Input a parameter number in the range of 1 (light) to 10 (dark)
