Have you had control box2 out of the machine?

I have found this can happen if it has been removed and upon installing it the contacts don't line up properly.

I have had to remove and reinstall them several times before they would work properly.

We tried that several times but it still didn't work. The display still stays orange without turning on.
Thank You

Thank You

have you updated the firmware?

can you get into service mode to check the error log?

you gave us little info for us to help you, and frankly I don't like to play dentist and pull the info from you.

have you checked voltages going into and from the LVPS and HVPS?

do you hear motors spinning?

In my experience with these units if this happens its usually the Main Network Board. Remember to swap eeproms if you replace this board.

Re: Printer MX-4111 not turning on

Thank You all for the responses, the machine never turns on so there is no way to get into service mode or update firmware. The fans do turn on but after a few seconds turn off. We are currently looking to get a hands on another similar model to swap the main power board and hopefully see if it fixes the issue.
Ill give an update soon

I would even try a SD card on that problem. Sounds as if it fails to boot properly.
I keep blank SD's because so many fail, and burn them myself.

Good luck!

SD card would be my first recommendation. Anytime a sharp machine has issues with the boot process and shows power with either a blinking light or an amber light it may be an issue with the boot process which is controlled by the SD card on older machines. Sata and eMMC on newer.

Unplug the HDD and see if you can force an E7-03. If not, SD would be the next thing, followed by MFP pwb.
If the unit has a fax kit attached, go right for the SD.

Orange light means something is up with the dc power supply. Replace that. They are known to go bad. Same thing for cycling green orange light.

Thank you all for your help! We managed to find the problem, it turns out that their electricity on their building was not sending enough to the machine. When we brought their machine to our shop it worked fine. We ended up replacing the harddrive and SD card

Current or voltage? I hate fighting the battle of low or dipping current. I have found most electricains know less than me when I try to explain the problem is likely a lack of current. Nope, they say, it's a steady 120 volts. Ugh!

I had a call for fuser temp errors and went round and round with an engineer at the local electric company who had put their copier on a spooled up 100' extension cord. He was at least 30 years my senior and got all scientific on me. I told him I would be happy to return when they plugged it back into an outlet.
