Firmware Version Update Procedure
-
Connect the computer and the printer by using a USB cable.
Remove any cards if they are inserted in the card slots.
Make sure that only one printer is connected to the computer via a USB cable.
If you are using Mac OS, make sure that sleep mode is disabled on the computer.
-
If you are using Windows, double-click 
(Printer Update.exe) to start the Update utility
If you are using Mac OS, double-click (Printer Update) to start the Update utility
-
Check the contents of Step 1 that is displayed in the Printer Update Utility, turn on the printer power, and then click Next.
If an error message is displayed, the possible causes are as follows:
-
Cause (1): The USB cable is not connected.
Corrective action: Connect the USB cable, and start over from step 1.
-
Cause (2): The downloaded update file is for a different printer.
Corrective action: Download the file for the printer to be updated, and start over from step 1.
-
Check the contents of Step 2 that is displayed in the Printer Update Utility, turn on the printer power, and click Start.
*Depending on the operating system you are using, the displayed operation windows may differ.
Printer name: Name of the printer connected to the computer.
Current software version: Software version of the connected printer.
Update software version: Software version to which the printer is to be updated at this time.
Do not turn off the printer or disconnect the USB cable until the update is complete. Doing so may cause an error.
If you are unable to click Start, the update was attempted on a printer that does not require firmware overwriting. Check the Current software version again. If it does not require the update then cancel it.
During the update, the error lamp on the printer will flash orange.
-
When the Step 3 window appears in the Printer Update Utility, check the message contents, and click Quit.
This completes the firmware update.
When the version update is complete, the printer power turns off automatically. To use the printer, first disconnect the power cable, reconnect it, and then turn on the power again.
If the power is turned off during the update, the update will not end normally.
If the printer does not operate normally even if you turn off the printer power and then turn it back on again, the update may not have ended normally.
