interruption of a firmware update procedure or other functions that
involve writing to main storage (SSD) poses a potential risk to the integrity
of the firmware on the SSD. The Scan2Net operating system of any
WideTEK® or Bookeye® scanner is Linux based and although it is very rare,
Linux can be corrupted like any other operating system.
If the Linux operating system or other parts of the SSD are damaged, there
is still no need to replace the SSD, at least not until the recovery procedure
is performed once. These recovery procedures are similar to the
procedures necessary to restore other operating systems to a previous
state.
Restoring the SSD to the factory default state
In a Scan2Net® scanner, an image of the Scan2Net Linux is stored on the
recovery partition at specific times. The image is created at the time of
manufacture, as well as at all times when an SSD had to be replaced.
Preparations for recovering an SSD
➢ Make sure you know the IP address, subnet and gateway of the scanner
that is valid for the network or have the network administrator
available.
Turn off the scanner either from the touchscreen, from the
Scan2Net application currently in use, or by pressing the POWER
button. If the device does not go into standby mode, press and hold
the POWER button for more than 5 seconds to hard-switch the
scanner into standby mode. If the device does not hard-switch into
stand-by mode, press the MAIN SWITCH to the "0" position to turn
off the scanner.
Make sure that the following process is not interrupted by a hard
shutdown or power failure.
If this process is interrupted, loss of the system restore point is
possible, so the SSD must be physically replaced.
