Dell 1350 Color User Manual page 228

Enter 5 in Sleep to put the printer in the Sleep mode five minutes after it
finishes a job. This uses less energy, but requires more warm-up time for the
printer. Enter 5 if your printer shares an electrical circuit with room lighting
and you notice lights flickering.
Select a high value if your printer is in constant use. In most circumstances,
this keeps the printer ready to operate with minimum warm-up time. Select a
value between 5 and 30 minutes for the Sleep mode if you want a balance
between energy consumption and a shorter warm-up period.
The printer automatically returns to the standby mode from the Sleep mode
when it receives data from the computer. You can also return the printer to
the standby mode by pressing any button on the operator panel.
