MX-M453N will send but not receive faxes

Re: MX-M453N will send but not receive faxes

The customer was waiting for a faxed doc from another department and when they called to ask where the fax doc was the other department said the the customer's machine was not answering.
Up to that point incoming and outgoing faxes were not an issue.
FYI. These machines are installed in a high security prison. I am severely limited as to what I can bring in to do diagnostics. No phones or computers etc. Getting a USB jump drive with firmware into the area took special permission. I am unable to use the web to change anything on the machine. Whatever I do must be done via the machine's screen.

Wonder what would happen if you bring drum starting powder(dusting pouch) with you and they find it

Are they aware not all the options are on the copier screen and some things have to be changed by the web browser?

This is the problem with dealing with prisons. Their rules make it damn near impossible to do any work. The person in charge of policy doesn't have to deal with the problems.

I installed a cheap portable fax next to the MX453N and it both sent and received. The 453 will fax out but does not answer when the modem rings. Since I had another 453 machine in the facility I took it's fax module to trouble shoot. I got the exact same response; send but not receive.
this machine is not networked and has worked perfectly since June when installed until last Thursday.

How did he sneak in the "cheap portable fax"..?
I dare think of hiding places....ouch.

If you wanna get to the web page, use a laptop and a cable. You don't even need the crossover cable with new machines.

Make sure not a simple DSL issue requiring DSL filter on fax line. We had similar issues with ATT Uverse and a cheapo Brother fax worked almost every time but the Sharp FXX2 did not until filter was installed.

The fax problem was resolved when I reset the machine to factory defaults. They haven't had an issue since I did that. However I have been called twice for a U6-00 code. The first time it was cleared by the time I got there. Today I got another call that the U6-00 code had popped up again. Since it is after 3:30 they are all gone for the day. I will make the 80 mile trip again in the morning. Anyone hear of the U6-00 code? Is there anyway this may be related to the original fax issue? It doesn't appear to have any connection that I can figure out.

U6-00 is Desk Paper Feed Unit trouble. Reseat your connector from the extra trays to the MCU PWB.

I think Dave may be onto something with the VOIP system. Sharp fax kits are not very VOIP friendly. You can try the usual tricks like slowing the baud rate to 9600, change coding to MMR, and turning off ECM. I have had at least 2 instances were the line level was not loud enough to trigger the fax kit, both were after an analog to VOIP conversion.
The newest Sharps have a Digital Line check box which helps with VOIP systems.

What SWS's do you use to change the baud rate and coding? I'm always nervous to change SWS so I want o be certain i'm changing the right ones.

SW27 : 00111111
SW28 : 11111101
SW29 : 01000101
SW72 : 01000110

Works for FXX2, FXX3, and FX11.
