MX-6240N Becoming unresponsive

[Madnhain]

Greetings!
I've got an issue that must be resolved this week.
An MX-6240N, its display will become unresponsive and freeze periodically. Eventually the machine will reboot itself. The time frame where the freeze occurs is sporadic. Sometimes it's hours between occurrences, other times it's minutes.
This happens when connected to the network and when its network cable is unplugged.
SIM 60-1 indicates that ICUM SLOT2 is INVALID, I replaced that memory.
There is a Data Security Kit installed. The Firmware is current.
Everything works normally with the exception of the freezing display.

We have considered uninstalling the data security kit though we are not sure that would help.
I will attach a pdf with a 22-6, the 60-1 screen the part that was replaced and an image of the PWB.
I would very much appreciate any ideas on this.

Thanks!

The photo shows the FR36 ROM installed but the 22-6 shows no security??? Is that why Slot2 is invalid?

Just noticed Slot 2 is unoccupied (no connecter for the DIMM), that is why it's Invalid.

Socket 1 and 2 are for Prog1 and 2 ROMS.

Attached is the updated 22-6.
I just went out there to investigate and for some reason the product key didn't stay in. I know I entered it because I was training a guy on how to do all that on this machine and entering the product key was part of that... weird. It's showing up now.
While I was out there I tested the outlet to verify it had the proper power and turned off WSD in case there is anything on their network that is causing issues.
I spoke with the Regional Sharp tech, he says that the "invalid" is normal on the 60-1.

I also just spent the better part of an hour trying to get it to freeze with no luck.

Any thoughts?

Thanks!

Re: MX-6240N Becoming unresponsive

The DSK info resides on the HDD. If the product key "didn't take", you may have a failing HDD which can cause a plethora of issues, including freezing. Test the HDD using SIM 62-2/3.

HDD R/W test both execute normally.

Re: MX-6240N Becoming unresponsive

Interesting.
Are they using user codes or the built in Device Control preset by chance?

Nope.

hi
if possible remove the security kit
test the mfp in standard mode

Re: MX-6240N Becoming unresponsive

It doesn't appear to be possible to remove the DSK.

Re: MX-6240N Becoming unresponsive

Update time.
So I went back to check the voltage again. The customer had an electrician install a 220v outlet specifically for this machine. Apparently this outlet is on a shared breaker with their IT room which powers a few servers and UPS devices along with a plethora of other equipment. When I went back to test it, the outlet was only supplying 199v.
The customer is in the process of correcting this issue.

Re: MX-6240N Becoming unresponsive

We work into the deal pricing a line conditioner ( almost $1500) with every one of these machine. It takes input voltage from 184v - 264v and pegs it at 208v; a must have in my opinion. It even uses the same outlet as the Polaris Pro..bonus!!
I have attached the spec sheet:

That sounds like an excellent product. I'm going to have to look into it! Thank you sir.

Re: MX-6240N Becoming unresponsive

I actually had this same problem with a MX-M620. The screen would freeze, and the machine would become unresponsive.
I would reset it, with the same results. I changed out the fuser, Hdd, and SCN roms, with no result. It ended up being a bad Boot Rom.
Hope this helps.
