If A Power Failure Occurs - Canon MF4600 Series Basic Operation Manual

If a Power Failure Occurs

If power is suddenly lost due to an outage or accidental unplugging, a built-in battery
retains the user data settings and the speed dialing settings. Any sent or received
documents stored in memory are backed up for about 30 minutes.
During a power cut, functions are limited as follows:
– You cannot send, receive, copy, scan, or print documents.
– You may not be able to make telephone calls using an external telephone, depending on
the type of telephone you use.
– You can receive telephone calls using the optional handset. You can also receive
telephone calls using an external telephone depending on the type of telephone you
use.
To fully charge the built-in battery, it takes approximately 12 hours when the main power switch is on. If the
built-in battery is not fully charged, the data may not be saved properly.
