Sharp Mx-3100 error L4-11

Re: Sharp Mx-3100 error L4-11

Sharp can likely flash that board at headquarters. I've had a brand new MX3100 once that came with a mismatched eprom error on bootup. The factory had not loaded the serial number on the machine. The only way to fix it was to take the main board to Sharp and they had 1 guy in Canada that had the "power" to flash it with the correct serial number. I would suspect this to be a similar situation, head tech support for your country may be able to fix it but, a normal sharp dealer would not.

Re: Sharp Mx-3100 error L4-11

I called the local sharp dealer last friday. Since the hard drive was remove and reinstalled (I did this) and installed the firmware for the machine, the finisher fxn9 didn't work. The sharp dealer says that's a problem with firmware. The firmware once it reflashes is newer than the firmware on the fxn9 board. So, what happens it wipes out the IC chip. He says it's a known bug. Whats needed to be done is to flash the new firmware but have the fxn9 unplugged. Wait till firmware is done and plug the unit back in. Since I didn't know this you can't reverse it now. He was suggesting buy a new PCB board for the inner finisher for $300 bucks. I have tech guys here that can remove the eeprom from the board but, "the sharp dealer says" even if you did do that you don't have the software binaries to flash it correctly. Meaning the sharp copier won't know the finisher is there because no software can be loaded to even know that. Has anybody had this type of problem before?

Your lucky! you figure out by you self how to remove the shift plate. Now its time for you to figure out PCU power board communication error...Good luck...

Re: Sharp Mx-3100 error L4-11

I've actually figured out how to move the shift plate to the home position and sensor. When I turn the machine on it does not show an error code L4-11 but, now it shows F1-00 which is the inner finisher. I'll unplug the fxn9 finisher power cable and remove the dummy punch and try to replicate the problem again later tonight.

Re: Sharp Mx-3100 error L4-11

Hello,

I just bought this machine and took it home to my house. Had to flash the firmware because the unit had no hard drive. Found a used hdd and put it in and flash the firmware. Unit boots up fine but, has an error code I'm not familiar with. I called a service company and they want money to fix it. I do know this unit did not have a sorter attached to it. I attached a short video on what it is doing. Any help on how to fix this problem myself would be appreciated.

thanks

Patrick

I know it is a shocker , but service companies are in the business of receiving money for their services. That's why they are businesses, not charities.
Now that I've had my fun with you, try the following:

Power the machine all the way down; sub power then main power off. Plug in the finisher and power main switch then sub power on.
Main is behind the door, sub is on the op panel. If the noise is still there, it is due to the machine not recognizing the finisher as attached and the shift motor is kicking in. As suggested above, remove the dummy punch AND fixing plate, unplug the finisher and boot up; the noise should cease.

Ok, having no experience in this what is my next step?

Re: Sharp Mx-3100 error L4-11

I removed the back panel and checked fuses. All are ok. I tested them with a 9v batter and test light. I removed the dummy punch module and ran the machine. Still same error and loud noise. What's next?

The dummy punch unit does not secure the shifter; the Finisher fixing plate locks it in place.

Re: Sharp Mx-3100 error L4-11

Try to disconnect the finisher and remove the dummy punch module and run the machine. The noise seems thesame, that if the finisher MX-FN10 is removed but the RB-X3 paper pass is still connected thesame noise as i've heard with your video. Hope this will help.

Re: Sharp Mx-3100 error L4-11

Looking at the pictures on the internet of a FNX9 is correct that's what I have on my copy machine. Not a FN17.

OK, next step is checking the fuses. You can verify the model and serial number on the silver tag on the rear of finisher when it's been pulled away as one of your photos show.

Re: Sharp Mx-3100 error L4-11

FYI I was just reading the manual and saw the FN-17 finisher. I'm not sure exactly which one it is. I only said the FN-17 because it looks very similar to the one I have. It has NO hole punch but it staples. "Faxman28" you said remove the dummy punch unit and make sure the shifter is captured by the mounting plate for the dummy punch unit. Well, I don't know what I'm looking for. Is there a picture in the service manual that shows this step? Zootech, I'll pull off the back panel tonight and check fuses. That's easy!!!! Again

Re: Sharp Mx-3100 error L4-11

the finisher should be a fnx9 for the 3100, if you leave the finisher unplugged and turn on the copier does it make a rather loud noise (gear grinding). If it does make the noise, that is the shifter trying to go to home position. If it is a fnx17 finisher that could be the cause of the error code.

I was just checking that when you posted, total brain fart here. He could try to find an FNX9, or he could remove the FN17, and place the center tray.
I just looked at an FN17 and it doesn't look like the photos posted; I'm confused, because the photos are of an FNX9.
TC 22-10 would show a finisher even if the shifter was not locked in placed.

Also remove the dummy punch unit and make sure the shifter is captured by the mounting plate for the dummy punch unit. the shifter probably just came loose from the move,

ok, I'll do that tonight once I get home from work. Thank you.
