Configure your computer settings so that it will not enter sleep mode before performing the firmware update. If using the fax functions, disconnect the telephone line from the main unit. To prevent problems resulting from operations performed on other computers during the firmware update, performing the update using a USB connection is recommended. If your computer enters sleep mode, the firmware update may not be performed properly. Do not turn off the device power, or disconnect any USB or LAN cables while the firmware update is in progress. If signals/data (print jobs, etc.) are sent to the device from another computer or application while the firmware update is in progress, a critical error may occur. If the update operation is performed while the device is processing other operations, or while images are stored in memory, those other operations will be canceled and the images stored in memory will be lost.

If the Error indicator is on or blinking, refer to the e-Manual and resolve the issue, and then perform the update operation after making sure that the Error indicator is off. After the operation finishes, wait for the Processing/Data indicator to turn off. When the Processing/Data indicator on the operation panel is on or blinking, the device is processing operations. When updating the firmware, be sure to wait until all operations (copy function, etc.) are complete before beginning the update operation. *Please note the following restrictions when using this software.
