17. IC PROTECTOR
17.1Outline
• To increase product safety, this MFP has an IC protector 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 IC is provided with an over current protective function which works when the current exceeds the specified value to protect the IC from
over current.
For an IC that is provided with an over current protective function and being protected, if the problem is solved, the MFP will recover after
turning OFF/ON the main power switch without replacing the board.
• The following list contains IC protector installed in each board, related devices, and symptoms when an over current occurs.
