Error E10/E12/E14: Main cause: The main motor (M1)(M2)(M19) is faulty. The DC controller PCB is faulty.Mode of detection:0000 The clock pulse do not arrive for 2 secs or more after the main motor drive signal
For more help you can check the canon iR6000 service manual from below link: http://goo.gl/yhuA4J
The 24V output from the composite main power supply PCB is absent for 1 sec or more
The wiring is faulty (short circuit, open circuit). The composite power supply PCB is faulty. The DC controller PCB is faulty.
1. Connectors Are the connectors J204 on the main power supply PCB and the connector J300 on the DC controller PCB connected securely? NO: Connect the connectors securely. 2. Main power supply PCB Is 24 V supplied by the main power supply PCB (J204) to the DC controller PCB (J300)? (J204-5 <-> J300-5: OVU3, J204-6 <-> J300-6: OVU3, J204-7 <-> J300-7: 24VU3, J204-8 <-> J300-8: 24VU3) NO: Replace the main power supply PCB. YES: Replace the DC controller PCB.
50.6 error is an open fuser heating circuit between the fuser and low-voltage power supply. Problem could be the fuser, the low voltage power supply or the DC Controller. The 1st thing to do is replace the fuser. If you have another one. You should really call a printer tech to look at it.
You might have either a faulty LCD cable or screen inverter board. The
LCD cable transfers data signal from the motherboard & video card
to the LCD screen. It also supplies high voltage DC power to the screen
inverter board. The screen inverter board works as a power supply for
the backlight lamp mounted inside the LCD screen. It converts low
voltage DC power to high voltage AC power needed for the backlight lamp.

58.X PRINTER ERROR alternates with 58.X PRINTER ERROR To continue turn off then on
A printer error has occurred where a memory tag central processing unit (CPU) error was detected, or there is a problem with the air sensor or power supply.
2- air-temperature sensor
3- DC controller
4- power supply
Turn the printer off and then on.
Remove the printer from any universal power supply (UPS), additional power supplies, or power strips. Plug the printer into a wall outlet and see if this resolves the problem.
If the printer is already plugged into a wall outlet, try another power source in the building that is independent of the one currently being used.
The line voltage and current source at the printer location might need to be inspected to ensure that it meets the electrical specifications for the printer. (See the printer User'sGuide for information about electrical specifications.)
If the message persists, contact HP Customer Support.
it's a Power Supply Fan error,it is on the right-hand side,and below.
Reseat connections to the specified fan and DC controller. If the error persists, replace the specified fan. If the error persists Replace the DC controller
Use the Figure and table below to properly identify the 57.X error and the corresponding fan that is causing the error message.
The 57.03 error relates to a problem with the fans, in particular, the right fan. Try reseating the connector for the fan in the DC controller board. (DO THIS WITH POWER DISCONNECTED!!!)
If that does not fix the problem, it is most likely the DC controller board failed, which will have to be replaced.
Hope this helps you out,
