17. IC PROTECTOR
17.1 Outline
• To increase product safety, this MFP has an IC protector (ICP) installed in each board. ICP is a component that protects IC. If the amount
of the current supplied to the electrical parts such as motor exceeds the set level, ICP trips to protect IC from over current.
The following list contains ICP installed in each board, related devices, and symptoms that occur when ICP trips.
