README DNP DS620 Printer v4.33 Firmware Update Utility for Mac OS
2024-10


General Information: 
This firmware update utility will install v4.33 firmware onto the DS-620 or DS-620A photo printer.  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.  

Important Note: 
The v4.xx firmware for DS620 is backwards compatible. It is supported in all current and older gen DS620 printers. However, the new v4 generation DS620 printers starting in late 2022 cannot accept older v1.xx firmware versions, these are identified by Serial Number prefix “DA6C”xxxxxxxx. 
The previous gen DS620 printers up to late 2022 have a SN prefix “DS6C”xxxxxxxx and can accept the v4.xx firmware or the older v1.xx firmware.

The firmware update utility for Mac supports versions Mac OS-14 Sonoma and OS-13 Ventura. It may operate on previous Mac OS, but older OS is not supported.

Brief Operation Information for the Update Utility:
To use this firmware update, please review the detailed install instructions that accompany the update utility or download it from the DNP web site.  

Ensure the printer is Idle and has print media loaded.  
After unzipping (ZIP) the files save the contents to your computer desktop or folder. 
Review the update installation information, then run the update application file.  


Summary of directions:
1- Confirm your DS620A printer is connected and powered on.
3- Select the folder with the correct version of the update tool, double click correct folder.
4- Double click the Firmware Update file DS620_v433…
5- Follow the directions of the application as prompted.

NOTE: The LEDs on the printer will flash while the firmware is being updated.
The printer will "beep" several times during this process. 

Wait until the process has completed. There are two parts of the update that will occur automatically. 

DO NOT interrupt the process.  

A Dialog box will appear indicating completion.  

-The entire process will take about a minute to complete.

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.  

IMPORTANT CAUTION NOTE:  
DO NOT interrupt the firmware update process once it starts; doing so could damage the printer. 

DO NOT turn off or disconnect the printer or PC during this process. 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-DS-620 or DS-620A 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. 

The DS620 mainboard will transition to a new FPGA in late 2022 and will us FW version 4xx going forward. The predecessor DS620 up to this transition can accept v1.x firmware and the new v4.x firmware. The newer ones cannot. The v4.33 firmware will support both the current and older gen printers.

Release Notes for iSerial USB functionality:
Operational and usability improvements of the printer 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. 

With iSerial Function Enabled the following improvements occur:

- For Windows, with iSerial enabled 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. 

- For the Mac Platform, with iSerial enabled this printer feature will allow multiple DS-620 printers to be connected to the Mac.  All connected DNP DS printers must have iSerial enabled for proper operation in a multi printer environment.

NOTICE: The separate iSerial Enable Tool must be run to turn on, enabling the iSerial functionality for all DS-620 printers and DS-620A printers produced prior to 2016-01.  All DS-620 and DS-620A printers are factory enabled onward from SN: DS6X59007831.
