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.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Technician (only for users in the US for now) and get all the help you need. Goodluck!

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.

It can be that You have problems with DC contoller ( main pcb ) or the copier is in worst condition and there are faults on every segment.
For E001, you can try to reset error:
1. The following error codes cannot be reset by merely turning off and then on the main power. They require resetting in service mode: E000, E001, E002, E003, E004, E032, E717 1) Start service mode, and select COPIER>FUNCTION>CLEAR>ERR. 2) Press the OK key. 3) Turn off and then on the main power. 2. Error codes other than the above may be reset by turning off and then on the main power. n Detail Code Some error codes offer detail codes, which may be checked in service mode: COPIER>DISPLAY>ERR (3rd block from the right)
BUT I THINK THAT THE BEST SOLUTION IS TO CALL SERVICE TO RECTIFY THE PROBLEM OR YOU BUY NEW MACHINE:..
E805 error code means failure of one of the many fans inside the
copier. If there is not a dash with four numbers after the 805 code on
the display, it is one of two fans - FM1 the transport bed fan or FM9 -
the reversing fan just below the fuser assy. There are several checks
that can be done but a too lengthy to be described. A tech maybe the
best answer depending on your mechanical ability.
The fan wiring is faulty (short circuit, open circuit). The heat dischargefan is fautly.
check wiring of heatdischarge fan
The machine is equipped with a single fan for discharge of heat from inside it.
An E805 code has to do with the failure of one of the many fans within the copier.
