Controlled power-down sequence Before performing the controlled power-down sequence, determine if
the error can be addressed from the host. If so, perform the required
host recovery procedures. If the error cannot be addressed from the
host, or if the scanner’s error message cannot be cleared when the
host recovery procedures are performed, continue with the following
power-down sequence.
1. Wait for all information current ly held in the buffer to be transferred
to the host system.
2. If necessary, prepare the host and corresponding system
components for a scanner power-down, per host system
instructions.
3. Turn off the scanner power for at least 5 seconds, then turn the
power back on again.
4. If necessary, determine the last image transferred to the host, reset
the image address and image level to the correct values, and
rescan all documents whose images have not been transferred to
the host.
5. If required, calibrate the scanner before r escanning .
6. If the error condition is not cleared using the controlled power-down
sequence, contact Service.
