About Restrictions in Sleep Mode and Deep Sleep Mode

This section describes the restrictions when the printer is in Sleep mode and Deep Sleep Mode.

If the printer displays an error, the printer may not enter Sleep mode and Deep Sleep Mode.

In Sleep mode, the network function is restricted as follows.

The printer does not enter Deep Sleep mode

The printer does not enter Deep Sleep mode in the following cases.

  • IPSec is enabled

  • A TCP connection is established

    Example: A connection is established with TELNET or FTP.

    When the transition time to enter Sleep mode and Deep Sleep Mode from Power Save mode elapses and the connection is disconnected, the printer enters Sleep mode.

Memo

To enable Deep Sleep mode, disable IPSec or E-mail reception.

  • SNMP Trap

  • WINS*1

  • SNTP*2

*1 The elapsed time in Deep Sleep mode is not included in the intervals of WINS update time.

WINS regular updates are not performed in Deep Sleep mode, possibly resulting in names that are registered in the WINS server being deleted.

The printer automatically enters Sleep mode from Deep Sleep mode.

In a network environment where a large number of packets are sent, the printer automatically exits Deep Sleep mode to Sleep mode and responds.

Also, if a terminal that runs searches with Bonjour, such as Mac or iPhone, is connected to the same network, the printer automatically exits Deep Sleep mode to Sleep mode and responds.

When the transition time to enter Sleep mode elapses, the printer automatically enters Sleep mode. When a certain period of time passes after the transition, the printer enters Deep Sleep mode.
