Specifies the length of time until the printer enters the sleep mode
if there are no printing or control panel operations.
Time Out
Specifies the length of the time the printer waits when it is ready
to print and no new data is received. When this time is up, the
printer searches for new print data from other interfaces.
Paper Source
Specifies whether paper feeds into the printer from the MP tray
or the optional lower paper cassette unit.
If you select Auto, paper feeds from the paper source containing
paper that matches your Paper Size setting.
If an envelope size (IB5, C10, C6, DL, MON, C5) is selected as the
Page Size setting, paper always feeds from the MP tray. If you
select Thick, Extra Thk, or Trnsprnc as the Paper Type setting,
paper always feeds from the MP tray.
MP Mode
This setting determines whether the MP tray has the highest or
lowest priority when Auto is selected as the Paper Source setting
in the printer driver. When Normal is selected as the MP Mode,
the MP tray has the highest priority as the paper source. If you
select Last, the MP tray has the lowest priority.
