Check for update details in the Firmware History located at the top of the firmware download page (located on the TSC website). Prior to install, disconnect network connections, Fax lines and any Fiery Controller interface cables. Refer to the Firmware Update Procedure in the Service Manual to determine if the Front Cover of the machine should be open or closed during the update (some models require the front cover open to reduce electrical noise). Additionally, follow any machine specific instructions. Never connect or remove the PC Card with the machine power on. Some firmware takes time to load. Do Not power off until machine completes update. Do not leave the machine unattended. If a power failure occurs during the firmware update procedure, turn the machine power off / on without removing the PC Card. The firmware update procedure should start again.
