Do not disconnect the power cord from the projector while the
firmware is updating. If the power cord is disconnected, the
projector may not start correctly.
All of the projector's indicators turn on and the projector enters firmware
update mode. The computer recognizes the projector as a removable disk.
f
On the computer, copy the firmware file to the root folder (highest folder
in the hierarchy) of the removable disk.
• Do not copy any other files or folders to the removable disk.
Otherwise, the files or folders may be lost.
• The projector turns off automatically if the USB cable or the
power cord are disconnected before the firmware file can be
copied to the removable disk. If this occurs, perform the
procedure again.
g
Perform the steps to safely remove a USB device from the computer and
disconnect the USB cable from the projector.
All of the projector's indicators start flashing and the firmware update
starts. When the update finishes normally, the projector enters standby
status (only the power indicator is lit blue). If Direct Power On is set to
On in the projector's Operation menu, the projector turns back on again.
When the update finishes, check the Information menu in the projector's
Management menu to make sure that the Version information has been
updated to the correct firmware version.
• When all indicators flash rapidly, the firmware update may have failed.
Disconnect the power cord from the projector, and then reconnect it to
the projector. If the indicators continue to flash even after reconnecting
the power cord, remove the power plug from the electrical outlet and
contact Epson.
• If no operations are performed for 20 minutes in update mode, the
projector turns off automatically. If this occurs, perform the procedure
again.
