Riso MV Series

Firmware Downloading Procedure

1. Switch OFF the machine power.
2. Remove the download slot cover from the side of the rear cover, on the paper-feed side of the machine, by removing one screw (M3x6 : 1 pc).
3. Insert the downloading CF card in a card adopter, containing appropriate firmware for the Mechanical control PCB and SH4F PCB for the specific machine model.
4. Turn ON the machine power. The firmware for the Mechanical control PCB is automatically downloaded the first. The green LED 3 on the SH3M2 PCB, as well as the LED on the wake-up key on the operation panel starts to blink. The program is being downloaded.
5. When the green LED 3, green LED 2 and LED on the wake-up key changes from blinking to a solid light, the firmware downloading to the Mechanical control PCB is successfully finished. The firmware downloading to the SH4F PCB starts automatically. The green LED 3 lights solid, and both the green LED 2 and the wake-up key LED blinks to indicate that the downloading has started. The firmware downloading to the SH4F PCB is successfully finished when the green LED 3, green LED 2 and wakeup LED all lights solid.
   * If a red colored LED 1 aside the download slot blinks and the wake-up key LED changes to a solid light, the firmware downloading to the Mechanical control PCB went through an error and ended unsuccessfully.
   * If a red colored LED 1 aside the download slot lights up to a solid light and the wake-up key LED changes to a solid light, the firmware downloading to the SH4F PCB went through an error and ended unsuccessfully.
   In both above cases, if the downloading ended unsuccessfully, the firmware downloading procedure must be repeated from the very beginning, which is step (3) of this procedure.
6. After the firmware downloading is successfully finished, switch OFF the machine power and remove the downloading CF card from the machine.
7. Mount the download slot cover back on the machine.

Downloading the DSP Software

Note:

The DSP Software is required to synchronize the Second Paper Feed Motor to the Main Motor. The DSP Software is download in the Mechanical Control PCB. If the Mechanical Control PCB is replaced, the DSP Software must be downloaded

The DSP Software changes the speed of the Second Paper Feed Motor when feeding the paper from the second paper feed area to the print drum, according to the print drum angle when the Timing Roller and Guide Roller start feeding the paper. This control action keeps the image print position constant on all the prints. The DSP Software also controls the Second Paper Feed Motor speed the moment the print drum pinches the leading edge of the paper. When the leading edge of the paper arrives at the print drum, according to the paper size and to which print drum the paper is sent to, the trailing edge of the paper is still pinched by the Timing Roller and Guide Roller. The DSP Software makes sure that the Second Paper Feed Motor feeds the paper in the same speed as the print drum to ensure smooth paper feeding through the printing area to prevent smeared image which may occur if the Timing Roller and Guide Roller pull on the paper during the printing.

The DSP Software version should match with that of the Mechanical Control and SH4F PCB firmware. The compatibility information on the firmware program versions will be issued at the same time when updated DSP Software is announced.

1. With the appropriate firmware for the mechanical control PCB and for the SH4F PCB downloaded, turn ON the machine in test mode to confirm that the machine properly goes into Test Mode.
2. Switch OFF the machine power and insert the download CF card, in an adopter, containing the DSP software.
3. Launch Test Mode and run Test Mode No. 102 [DSP Download (Main, Secondary)].
4. Check the operation panel and make sure that the download is completed (The download should take around one minute).
5. Switch OFF the machine power and remove the CF card.
6. Launch Test Mode again and run Test Mode No. 126 (Optional Configuration Check). Check the software version on the display to confirm that the DSP Software is upgraded.
7. If an error occurs during this process, repeat the procedure from the beginning.
