Ir 2020 e805


E805- Fan Failure- open rear cover find PSU and check for rotation of cooling fan at power up ( spins as soon as display lights up)
If it isnt spinning - replace with correct part from Canon, the circuit is expecting a feed back specific value which will only be seen with the correct fan.

Ihave canon 400 problems. e051, e901, e805 problems frequently please suggest me


Hello,
by the look at your problems:

E051 - Horizontal registration sensor problems
E001 - Fixing temperature faulty
E805 - The Fan rotation problems

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:..

Hope that helps!

My copier is having a system error E-805


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

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

I have a Canon Image Class 6550 and keep getting error code E805 Please help me find a solution.


Hi,
the e805 means that you have bad fan. The fan is located under back cover.
There are two possibilites:

1) Reconnect the fans connector, and connectors on dc controller - main pcb. If that doesnt help, on electronics hardware store or in computer shop find the fan of same dimensions and replace it.

2) the dc controller is bad, and you need to replace it with new one.

Canon Error Message


An E805 code has to do with the failure of one of the many fans within 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.
