If a Power Cut 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 the memory are
backed up for about 3 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 a telephone connected to the machine,
depending on the type of telephone you use.
•
You can receive telephone calls using a telephone connected to the machine depending on the type
of telephone you use.
If You Cannot Solve the Problem
If you have a problem with the machine and you cannot solve it by referring to the information in this
chapter and Chapter 9, "Troubleshooting," in the User’s Guide, contact your local authorized Canon
dealer or the Canon help line.
