Power Button - Starting Up and Shutting Down the PSA

Press the Power button to power up the PSA. The bootup process begins. When the device is powered on, the Power LED is lit. To turn off the PSA, press the Power button and wait for about 20 seconds for the PSA to power down. The PSA performs an orderly shutdown.

If print jobs are printing when the PSA is powered down, the print jobs will not be completed. Jobs waiting to be printed will resume printing when the PSA is fully booted. If the PSA loses power unexpectedly and is not powered down, spooled print jobs that had not yet begun printing or print jobs that were in the middle of printing will resume printing when power is restored and the PSA is powered up again. If, however, the integrity of the PSA or print jobs are compromised, print jobs that were not spooled would have to be resent.
