55. The RISOiQualitySystem built into all new RZ series models is a radical new way to ensure that the users of RISO printers get the very best performance from their RISO printers, automatically.
The System allows two-way communication between RISOiQualitySystem
equipped printers and their supplies - ink and masters – via tiny integrated RF-tags
Embedded in the ink bottle and master roll.
This two-way communication provides a host of important benefits that include :
Assurance of optimum print quality
Prevention of operator error for supplies
Warning of shortage in remaining volume
Minimal paper waste

56. The RISO i Quality System – real time control for ultimate quality
What is an RF-tag?
An RF-tag (= Radio Frequency-tag) is a film that contains an IC chip and an antenna.
Various data for activating the RISOiQualitySystem are stored in the IC chip, and this data is sent to and received from the RISO printer via the antenna.
About Supplies…
Each Riso ink has its own character and viscosity, requiring individual and precise adjustment of print pressure, idling time and operating speed to obtain maximum print quality. In addition, the sensitivity of masters varies between the start and the end of the roll. Current RISO printers adjust for these parameters
but only to a limited extent. The RISOiQualitySystem not only offers real-time adjustment all of the time, it also achieves improved print quality.
INK
The RF-tag embedded on the ink bottle communicates data such as colour, viscosity, etc. to the printer, preventing the selection of the incorrect colour and assuring optimum print quality.
MASTER
The RF-tag in the master roll stores and communicates data including master character and position on the roll for real-time adjustment of the master making parameters. This allows optimum print quality.

57. The RISO i Quality System – Functions and Features
OPTIMUM PRINT PRESSURE CONTROL
Print pressure is automatically optimised based on data received from the RF-tag in the ink bottle and the master roll to assure optimum results.
OPTIMUM TPH POWER CONTROL
Information from the RF-tag in the master roll is used to optimise the power of the thermal head based on the real-time condition of the master materials.
The RISO i Quality System – Functions and Features
Ink colour indication Thanks to the The RISOiQualitySystem, printers with
LCD panels now can show the ink colour on the control panel.
2. Prevention of mis-insertion of ink bottle If the user tries to insert an ink bottle of the wrong colour – for instance placing a RED ink bottle in a drum used for BRIGHT RED – the machine returns an error message and prevents mis-operation. This assures reliable and consistent colour reproduction.
3. Thermal head energy auto adjustment Data stored in the master rolls RF-tag includes the date of manufacture, position on the roll and master character. This information is used to automatically adjust the power of the thermal head to suit, resulting in optimised masters, every time and best possible print quality.

58. Idling time auto adjustment by interval from previous use ink character
The RISOiQualitySystem automatically adjusts idling time according to the combination of time elapsed since last use, ink colour and ink characteristics, to assure optimum quality from the start of a print run and to minimise paper wastage.
Print press roller auto adjustment to optimise first print quality
The RISOiQualitySystem combines information on ink viscosity, character and colour with details on master characteristics and data as to when the printer was last used to adjust warm up action and optimise pressure of the print roller for maximum quality from the beginning of the print run, to minimise paper wastage.
Print press roller auto adjustment for superior output The printer reads information on master character and ink viscosity, character and colour from the
RISOiQualitySystem and uses this to automatically set the optimum print pressure of the print roller for maximum output quality.
7. Precise, real-time feedback on remaining supplies A further advantage of the RISOiQualitySystem is precise real-time feedback on the amount of ink and masters remaining. When the remaining volume of supplies is near to the end, the RISO printer indicates the caution display so that the users need never run out of ink or masters un-expectedly.

59. Manual data input procedure for LED models
To optimise print quality, the printer receives information from supplies via the RF-tag. If that data is un-available for any reason, the
“i” indicator fails to light and an “H” is shown in the print quantity display.
Step 1: Enter a parameter using the print quantity keys.
Manual input parameters
H1 : Ink colour setting
Select the same colour as that of the currently installed drum.
1: Black 2: Colour
H2 : Print density adjustment (ink)
Perform fine adjustment to optimise print density according to ink.
1 (Light) to 5 (Dark)
H3 : Test printing print density adjustment (ink)
Perform adjustment of print density for test printing according to ink type and colour. This adjustment is independent to H2.

60. Step 2 : Press the start key to complete entry.
H4 : Master making density setting
Set the reference density for the master making process
1 (Light) to 10 (Dark)
H5 : Print density adjustment (master)
Perform fine adjustment to optimise print density for testing according
master.
1 (Light) to 5 (Dark)
H6 : Test printing print density adjustment (master)
Perform adjustment of print density for test printing according to
master. This adjustment is independent of H5.
Step 2 : Press the start key to complete entry.
If the next number appears, repeat steps 1 and 2.
Step 3 : When all data necessary is input, the print quantity display
returns to normal and is available for standard operations.

Power saving (Low power) mode.
With no error status on the machine, if no operation is made on the machine for 30 seconds, the
24 volt supply to the machine components is terminated. There is no sign for this power saving mode, so when using a multi-meter to check 24 volts on the machine this must be kept in mind.
Also when servicing machine, NO DRUM FREE ROTATION (FREE SWITCH) is accessible when in power saving mode. TO ACTIVATE 24 VOLTS, TOUCH KEYPAD.
Battery replacement
Replace the battery on the mechanical PCB with the machine power ON. (RZ3 series only)
Replacement of the mechanical control PCB
When the mechanical control PCB is replaced, it is necessary to record all the user mode and test mode settings. Therefore it is important to memo down all the user mode settings prior to the replacement of the mechanical control PCB.
The protected area test mode (those test modes which needs 9874 to be activated in advance)
are memorised in the EEPROM, so these do not need to be re-entered.
