Rebooting After a Firmware Download or Forced Firmware

Download (Description and LED Behavior)

When the user downloads an application (via either a normal

or forced download), the firmware file is written to the printer

flash memory and the printer is automatically rebooted.

When the printer is rebooted, the following occurs in the

printer:

1. Decompression of the downloaded application.

2. Writing process of all the executables, libraries and sup-

port files to the file system.

3. Starting of the normal application start-up process.

Steps 1 and 2 will take approximately 30 seconds. During

those 30 seconds the Green power LED will blink.

The normal boot-up will follow which will take the stan-

dard boot time of approximately 15 seconds. Therefore, af-

ter a firmware download (either normal or forced) the user will

see the Green power LED blink for approximately 35 seconds,

followed by a solid Amber LED and solid Blue LED for a final

overall reboot time of 45 seconds.

Shutting Down LED Sequence

To shut off the printer, press and release the Power button.
