display.
2 Press I TEM until I/O TIMEOUT appears on the display.
3 Press -V ALUE + until the interval you want (between 5 and
300 seconds) appears on the display.

Note If the I/O timeout is too short, print jobs might be incomplete. If the I/O
timeout is too long, print jobs might be unnecessarily delayed.
