ECOSYS M6635cidn fax errors

[kuby]

We have a M6635cidn that keeps getting U01011, U01026 and U01056 errors when faxing. It is hooked up thru a Fax Modem and the internet.
The setting are:
Port 1:
Communication Control 1:
TX start speed: 14400 bps/V17
RX start speed: 14400 bps
TX echo: 300
RX echo: 75

Port 1:
Communication Control 2:
ECM TX: On
ECM RX: On
CED FREQ.: 2100

Port 1:
Communication Control 3:
DIS 4BYTE: Off
NUM. OF CNG(F/T): 2 Time

Port 1:
Communication Control 4:
V.34: On
V.34-3429Hz: On
DIS 2RES: Once
RTN CHECK: 15%

Is there something I need to check, turn Off/On ? The Fax/modem has been replaced, printer firmware is up to date, line is clear.

Thanks

You say the line is clear. Did the line provider physically check the line? Did this just start happening?

It is hooked up thru a Fax Modem and the internet.

The fax modem is internal to the 6635cidn.

I need to know more about the telephone line being used...

It is a Spectrum Fax/Modem connected to the internet and then to the machine and faxes with a digital signal.

Try turning V34 off. You may need to reduce the TX and RX speeds lower than 14400bps.

Use this for the settings and make sure it's using a 2 wire line.
