Installing this firmware will add certain functionality to the printer. See the list of feature improvements listed below under firmware revision history. Installing the most current firmware version will include all improvements of the previous firmware updates. Installing each of the incremental updates are not necessary.

Ensure the printer is Idle and has print media loaded. After opening the disc image file (DMG) for MacOS, copy or save the contents to your computer desktop. Review the update installation information, then run the update application file. Summary of steps: 1 Confirm your DNP printer is connected and powered on. NOTE: If you are updating more than one DNP printer, it’s important to have only one printer connected at a time. 2 Confirm the printer is loaded with print media and Ready. 3 Select the folder with the correct version of the update tool, double click correct folder. 4 Double click the Firmware Update executable file 5 Follow the directions of the application as prompted. When the update begins, a NOTICE window will appear, informing you of certain criteria concerning the installation of the firmware onto the target printer. In particular, the notice points out the one-way nature of the update. NOTE: The LEDs on the printer will flash while the firmware is being updated. - The printer will "beep" several times during this process. - The computer display will show the update progress. - Wait until the update process has completed. - DO NOT interrupt the process. A Dialog box will appear indicating completion. - The entire process will take about a minute to complete. IMPORTANT CAUTION NOTE: DO NOT turn off or disconnect the printer or PC during this process once it starts. DO NOT unplug the data cable, or open the printer front door, or interrupt the update process in any way. The printer may be permanently damaged requiring costly repair. NOTICE: This firmware installation CAN NOT be reversed or uninstalled. The firmware may be installed onto a DS-820 or DS820A printer that is less than or equal to the firmware version in the update utility. Once updated with this firmware update package, a lower version firmware cannot be installed. Release Notes for iSerial USB functionality: Operational and usability improvements of certain DNP photo printers on Windows and Mac platform computers can be achieved with the addition of iSerial USB functionality. After the firmware is installed, the iSerial function must be enabled using a separate utility available from the DNP web site. The DS820 has this iSerial support by default. Certain DS620 and RX1 printers may require a firmware update and the iSerial function to be enabled to achieve the desired operability. With iSerial Function Enabled the following operation improvements occur: - For the Mac Platform, the iSerial feature will allow multiple DS-620, DS820, or RX1HS printers to be connected to the Mac OS-X. All connected DNP DS printers must have iSerial enabled for proper operation in a multi printer environment. - For Windows, the driver iteration DS-620 Copy 1, DS-620 Copy 2, etc are eliminated when the printer is reconnected to a different USB port. After the first reconnect after the FW update, it will automatically reconnect to any USB port on the PC the DS-620 was previously connected without creating another driver copy iteration. Notes: * Some new features and print sizes require the complementary printer driver update to enable and use the functions. ** Print media pack sizes are limited to certain sales regions, check with your local reseller.
