Had the same problem with my 420 CN. The only way I got it to work again was to unplug from power bar and plug directly into wall. Machine powered 4 seconds after I plugged it in. I hope it works for you too.

Lcd light has gone on MCF 210C Brother machine,


Possible failure of the power supply unit or the LCD unit of the printer. You will need to remove the power supply and check the voltage feed to the mother board and the sub panel LCD unit.
If there is supply to the unit then the LCD panel is faulty, if not the mother board has errors as it fails to communicate to the panel.

Machine display Full memory messege. Idone what


On this fax machine if you tried everything and still no luck, you might want to try to reset the main board.
This will reset the main board to factory settings.
When you do this, you may need to enter all your information back in again, speed dials, date, time, ect....
On this type of problem, sometimes this works, sometimes the problem maybe more indepth such as, replacing the main board on the machine. I am talking about the large mother board.
Hold down these buttons at the same time... Menu, 1, 3 and * button.
While holding these buttons, use the left hand to power on the machine, while holding these buttons for about 15 seconds...
When you let go of them, the machine should come back on to a normal screen.
There can be other changes in the memorywhen you reset the main board information.
If the machine does not come back on to a normal messege screen, you may need to replace the mother board.
Good luck.

Machine problem is DOWNLOAD STANDBY SOLUTOIN PLEASE


Hi there. I think the model is a Canon iR2016. If yes the problem is that the machine is not loading the firmware. The best solution is to get a new mother board for the machine. Just make sure you have the newer version of maotherboards. Having a different connector for the ROM board.

The printer stops during use and will not start back.


Michael Benson called me yesterday afternoon and spoke with me. He walked me through a check of the machine and agreed it is the mother board going out. He was very helpful and gave me several options of what could or needed to be done. I will speak to our mayor regarding this and get back with your company if we decide to buy a refurbished machine.

Michael was very helpful.

Thank you,
Lynn Rowland

Carriage door malfunction


There is a little sensor that goes back to the mother board that says the door is closed. This sensor may be malfunctioning because: the sensor itself is broken, or the mother board in the printer is not receiving the pulse. The wire that goes from the sensor to the mother board may be broken or pinched. You can contact HP.com to find out what part you may need.
thanks hope this helps Helen
Also you can look to see if debris is caught in the sensor area. Use a flashlight and dust sensor off.

Canon copy machine NP6025. Error E800.


According to what I have E800 is eith a problem with the Mains switch or DC controller. I doubt it's the switch but there are many things that would cause a DC controller error. You might try Hytec Board Repair for help on the DC controller. http://www.hytecrepair.com/
