Your problem maybe caused by a thermistor near the pressure roll in the fusing unit (the red roll).

Try the follow procedure and if it doesn't fix call minolta service.

1. Turn OFF the Main Power Switch.
2. Turn Main Power Switch ON while pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and the it has been reset.
5. After turning off the Main Power Switch, turn it on again more than 10 seconds after
and check if the machine starts correctly.

My Bizhub 350 is saying malfunction dectected C3452

This code means you have a fuser warm up failure. The fusing unit uses heat and pressure to "fuse" the toner onto the paper. It is located right where the paper exits the machine. Here is the info directly from the service manual:
The Fusing Roller Sub Thermistor does not
detect the required temperature within 30 sec.
after a warm-up cycle has begun; therefore, the
copier does not complete the warm-up cycle.
• The temperature of the Fusing Rollers does not
reach the required level even after the set period
of time has elapsed during a warm-up cycle.

Most likely you have a thermistor failure in the fuser. You are going to need to call your local service company and have them repair then reset the machine.
Good Luck and Thank You for using Fixya.
