[Error Code] EA31

[drolfe@webmail.co.za]

Having a problem with a MJ1104 finisher attached to estudio 5520c.
machine works perfect without sorter attached as soon as you plug sorter in and start up machine it goes straight into error EA31. have checked all connections and sensors ,l have replace sorter board but still gives error can anyone help

Re: EA31

Have you got a hole punch unit attached to the finisher?

Re: EA31

Hi Michael
No it doesnt have a hole punch unit on it

Re: EA31

Was kind of hoping you would say yes to having a hole punch unit lol. I've had a few instances where I also got the EA31 error and after countless searching and cursing, turns out that the hole punch unit waste containter had becomes extremely full at one stage and spilled(spluttered) out onto the sensors which had one firmly lodged between. That was a fun day ...

As for your EA31

[EA31] Transport path paper remaining jam


1. Check if there is any paper in the finisher or on the transport path of the equipment and remove it
if there is.
2. Check if the connector CN22 on the finisher controller PC board is disconnected from the
transport sensor (S2) or the harnesses are open circuited. Correct if any.
3. Reinstall the sensor correctly if there is any incorrect installation.
4. Replace the sensor.
5. Replace the finisher controller PC board.

There could be a chance that a sensor somewhere is faulty. When you checked the sensors, did you boot into ( 0 3 ) mode and go through the input test modes? Or did you just visually inspect them? From memory, there are around 140ish sensors in that model. Also, when you boot the machine in ( 0 8 ) mode and get a error history (Code 253) and check the if there was a pattern or other areas of interest. You can decipher the rest of the error history line which just tells you things like which draw was used on the jam, what paper type, duplex or whatnot, but I don't think that will be helpful in this situation, maybe eliminating a sensor or two not sure.

I can only suggest you visually inspect all the paper transport path sensors on the machine and finisher itself, which will involve pulling half the bastard apart, pardon my french (I really despise finishers), and run a sensor check on the transport path.

Good luck!

Re: EA31

Thanks Michael
the problem is def with finisher as it was plugged into another machine and same error.
i have traced the sensor s and even swapped the sensors around hopeing it would give another error and no luck, i have replaced the board twice still same error.
it is quite confusing as i dont know what next to do

Re: EA31

Unfortunately, since two days i suffer exactly same problem on a 5540 with a finisher MJ1103 equipped with Punch Hole Unit.
Swapped sensors; checked voltage levels (with a DMM) at CN6, pin 2, changes correctly between 0V and 3,1V when sensor is actuated by a strip of paper or not.
Disconnected Punching Unit with no luck.

Machine works fine if i disconnect finisher from it.

Service Manual says first: replace S2; second: replace finisher PWB. .

Tomorrow i'll try to escalate this issue to Toshiba, because i really don't want to buy a useless and very expensive new finisher board, and then having the same trouble.

Furthermore I have to say that Sensors Diagnostic on this kind of finisher is a real mess, because it cannot be made by 03 mode (as usual) but by a very difficult method that uses two finisher keys and three finisher 'control panel' LEDs. .

I will update this issue as soon as i'll got bad or good news...

(Sorry for my awful english)

Re: EA31

EA31 SOLVED - FIXED.

Hello,
I'm afraid something went wrong in my last Sunday's reply (14/02/2016) - I don't see it.


Today I returned to the customer and investigated again about this cursed code.

I surely found that service manuals are wrong (or not completed), because machine gives the same EA31 code for 'paper remaining at power on' NOT ONLY on S2 (like service manual say... ) but even for S22 (inlet entrance sensor).

In detail, today I founded S22's actuator spring has become weak, and actuator arm did not fully returns in its home position.
In this way sensor remain 'slightly' actuated, enough to 'send' a High signal (= paper jam) to Finisher controller PWB.

Furthermore, I then experimentally checked, on another 'healthy' machine equipped with same finisher (MJ1103 - MJ1104), that even actuating (by stripe of paper) S1, machine still shows the same useless code (EA31).

(I hope you all could understand my awful English - sorry)
Marco.
