Troubleshooting 
This section provides solutions to common update-related problems. 
If Initialization Does Not End Following a Firmware Update 
If the Home screen (touch panel models) or “Ready” (four-line LCD models) does not appear on the 
machine’s control panel after one minute following a firmware update, a power failure or similar 
interruption prevented the update from completing. 
If this happens, check “Before Updating the Firmware” again, and then use the following procedure to 
recover from the failure and complete the update. 
 
To be recovered following a failed update, the machine must be connected to a computer by USB. 
When using a computer running on a Windows operating system, you must have an account that has 
Manage Printers permission. Log on as an Administrators group member to acquire this permission. 
1.  If you performed the update through a network connection, disconnect the network cable, and then 
connect the machine to a computer using a USB cable. 
2.  After confirming that “blank page” or “Initializing...” has been shown on the machine’s control panel 
for more than one minute,   double-click the [FwUpdateTool.exe] (Windows) or [Firmware Update 
Tool] (OS X) icon to launch the firmware update tool. 
A dialog box with cautionary statements appears.
