Re: Comm 503

That is "CS of modem is not able to turn ON during training." It could be a bad SC circuit board, but usually that's a bad line or connection. Get your phone lines checked out by your phone company.
If that doesn't do it, then you'll have to replace the board in the fax machine.

Comm. code 400

the 400 code is some cases is due to incorrect transmission levels, try turning of memory tx and send directly, or could try adsl filter on the line if needed, there are things that techs will be able to adjust if necessary

How to get fax reports

Your only option is to have it print out automatically after every 32 transactions, print out after every transaction, or print out only when there was an error with the transmission.

That parameter is Comm Journal and you can get to it by going to Function 7, option 4. That should give you a fax parameter table. You want options 12 and 13. Set 13 to "1" if you want it to print out every 32 transactions. Set that to "2" if you don't.
Set 12 to 1 for Comm Journals Off, 2 for Always, and 3 for Incomplete Only (errors).

Panasonic UF - 560: Comm Journal page does not print

I could not find to the manual for your particular model, however the following should be close enough. Although you have set the Comm Journal to "On" you have to set the paramater to "Always" Download the manual at: Look at page 131. I think that will take care of it. IF NOT - PLEASE let me know before you rate this solution. I will research it further. Ed
