I have a canon imagerunner 330s and when i power it up it tells me to "Switch Main Power OFF and On" E805. I checked all fuses and they look good What else could it be? If anyone could help. Thanks Mike

Code
E805-0000
Description
Fan error
The Fan was locked for a specified consecutive period of time.
Remedy
Check the connection of the Main Fan. 2. Replace the Main Fan.

FM1 Heat discharge fan Cools fixing unit.E805 0000 Fan failure
only one in this copier>
The fan is faulty. -
Check the fan connector.
- Replace the fan.
- Replace the DC controller PCB.


Switching between full-speed rotation and half-speed rotation is controlled as described below.
1) Full-speed control
When the CPU on the DC controller outputs a fan full speed signal (FAN_FULL), the fan drive voltage switching circuit supplies a +24 V fan drive voltage to turn
the heat exhaust fan at the full speed.
2) Half-speed control
When the CPU on the engine controller outputs a fan half speed signal (FAN_HALF), the fan drive voltage switching circuit supplies a +16 V fan drive voltage to
turn the heat exhaust fan at the half speed.

E805-0000 (Main body fan error)
When the cooling fan of the main body starts, the fan lock detection signal (FAN_LOCK) has been held at the "H" level for longer than the prescribed time.

also check your low-voltage power supply

there could be a problem with the main fan and or the dc controller could be bad.

the fixing assembly need to be rebulit or the fixing gears need to be replaced. the main fuser motor is locking up which tells them the fixing rollers have flat spots on them and have finally caused it to stop rotating

in the power supply board

When switch on ImageRUNNER 330s Grayscale Copier then no display on dispaly board. But Copier front yellow led is on. Please solve this problem.

This is called low temperature check environment around copier or replace fuse in DC Controller

this is due to an open circuit or fuse on your dc controler board

This may be caused by an open fuse, FU201, on the DC Controller. Although the fuse is available (VD7-0623-000) you may choose to send the DC Controller to an Authorized Repair Facility, because it is soldered to the PCB or you may have to just replace the DC Controller. Could also very well be a pinched wire. First thing I would try would be open the back panel with the machine off then reseat all the connectors going into the DC Controller.

this will get you into service mode choose COPIER
then FUNCTION then
CLEAR then
ERR or ERROR then press OK(bottom right hand corner of screen)
turn power off then on

Thank you
