Sleep Mode
This product is designed with an energy-saving mode called Sleep Mode. The Sleep Mode saves energy by
lowering power consumption during extended periods of inactivity. The Sleep Mode is automatically engaged
after this product is not used for a specified period of time, called the Sleep Mode Timeout.
Factory default Sleep Mode Timeout for this product (in minutes): 15
By using the configuration menus, the Sleep Mode Timeout can be modified between 1 minute and 120 minutes,
or between 1 minute and 114 minutes, depending on the printer model. If the printer speed is less than or equal
to 30 pages per minute, then you can set the timeout only up to 60 minutes or 54 minutes, depending on the
printer model. Setting the Sleep Mode Timeout to a low value reduces energy consumption, but may increase
the response time of the product. Setting the Sleep Mode Timeout to a high value maintains a fast response,
but uses more energy.
Some models support a Deep Sleep Mode, which further reduces power consumption after longer periods of
inactivity.
Hibernate Mode
This product is designed with an ultra‑low power operating mode called Hibernate mode. When operating in
Hibernate Mode, all other systems and devices are powered down safely.
The Hibernate mode can be entered in any of the following methods:
• Using the Hibernate Timeout
• Using the Schedule Power modes
Factory default Hibernate Timeout for this product in all countries or regions 3 days
The amount of time the printer waits after a job is printed before it enters Hibernate mode can be
modified
between one hour and one month.
Notes on EPEAT-registered imaging equipment products:
•
Standby power level occurs in Hibernate or O mode.
• The product shall automatically power down to a standby power level of ≤ 1 W. The auto standby function
(Hibernate or O) shall be enabled at product shipment.
