I'm Really struggeling to get my 6655 to boot up. I cant use the connect key software upload because the machine wont go to the stage where my laptop picks up the ip address. I tried doing it manually via usb - still no success. i then replaced the hard drive but it still doesnt take software, replacing the ESS board was also unsuccesful so i put the old one back. the led lights on the ess indicates that the HDD and the sd card is picking up. I just need to load software but its as if the machine just doesnt pick up the usb, i tried a 4G usb and 8G usb, nothing picks up. The usb ports is enabled as well as software upgrade on the machine. Any thaughts on this problem???
The USB thumb drive must have max 8gb. and formated FAT32.
You must install the firmware with procedure bellow:
Download and unzip the firmware,
To prepare the USB thumb drive for an AltBoot restore, create an AltBoot folder, in the root directory. Next, using Notepad or similar utility, create a zero-length file in the AltBoot folder called FORCED_UPGRADE with no extension. Again, this file must reside in the ALTBOOT folder and be named exactly as shown. Finally, copy the latest firmware file (*.dlm) to the ALTBOOT folder.
Turn the printer Off.
Insert the prepared USB thumb drive in the USB Port on the printer’s rear panel.
Turn the printer On. The printer reads the USB port and begins the restore process.
The splash screen displays the ENERGY STAR logo while the printer reads the thumb drive.
The restore process begins with Check Firmware Version being displayed.
Next, the Software Upgrade screen is displayed. Depending on the system configuration (Trays, Finisher) the process can require approximately 20 minutes. The Software Upgrade screen changes to reflect the current subsystem being restored.
After the firmware update process is complete, the AltBoot Complete screen is displayed instructing you to remove the USB thumb drive and to press 0 (zero)
Remove the USB thumb drive from the printer’s USB Port.
Wait for the printer to reboot and return to Ready To Print.
They are needed during upgrades only, and only if you are on different revisions (071 or 072)
They are not at all to be used in an Altboot scenario
Go straight to the 073 release, Gabi's method listed wipes the device, there is no need of increments
