E.PU is a general power stage failure.

Without knowing the part number of the actual inverter with the problem it is difficult to speculate what the actual problem is.

One thing to do is to check if the fan is operating. Some of the older F5 inverters utilized a feedback loop so that the inverter could tell if the fan was functioning properly. If the fan was not functioning the inverter would trip into E.PU.

Model 451. What is error code 3B02?


The power supply that controls the fuser (The Hot part) unit is causing that code.


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.


DO THIS ONCE IF IT COMES BACK REPLACE THE FUSER POWER SUPPLY OR A FIRE CAN START THAT WILL RUIN A PERFECTLY GOOD DAY!

1994 Mazda PU Truck sometimes won't start if shutoff for 5-10 minutes.. Several tries later, it will start. spark seems ok, it gets enough fuel for a second, but then poops out. fuel pump shuto


Well there is no shutoff relay, but there is a fuel pump relay that powers the pump.
I would check it first. The computer grounds the relay for 3 seconds when you crank the engine to boost fuel pressure. Once the engine starts the pump is powered only if you have oil pressure.

that set is highly rated by users .. it first came out in early 2009 (i think) so you might check to see if any warranty remains ... the display is illuminated by several lamps .. each lamp has its own high voltage inverter .. all the innverters are powered by an output of the low voltage power supply (often 18 volts)... i would suspect a problem with that low voltage power supply.. either a bad capacitor or a thermal issue .. .. ..
