Ricoh 4501A Fax Receive Problems

[Yumann]

Dear All,

I have been a lurker on here for a while and have been using the very informative information. I would like to thank all in advance.


As above I seem to be having problems receiving faxes. I have turned of the ECM and it made a bit of a difference.

Can someone provide me with a service manual for the above printer for the relevant bits to adjust.

I want to slow it down to RX speed to 14400 but do not now the bits to adjust.

Is there any other settings that I can make to ensure better receptions. eg

Initial TX modem rate - set to 14.4
Initial RX modem rate - set to 14.4
PABX equalizer - set to high (both tx and rx)
PSTN cable equalizer - set to high (both tx and rx)
Reconstruction time - set to 12s

Can you the bit to adjust


Thanks

Apparently the MPC4501 has an auto speed step-down system to make sure the transmission has the best possible chance of sending. There are no speed settings in the UP's that I can find. Have you connected a normal phone to the line to check for noise? Is the machine using the correct fax lead?

Correct fax lead? I just found one that fitted is there a specific one.

I'll will check for noise on line. I take it that's a telecom provider issue.

Thank.

Yes, there is definitely a specific one. The part number is 11758X. Yes, any noise on the line will be a telecoms provider issue.

Thanks.

I have noticed the fax issue comes from one source/online fax provider.

I'll give the suggestions above a shot.


Thank again.

This may help. This is for a C4501, type c5000 D393 fax option.

That part number doesn't work in my system. What is this lead your talking about?

Can someone confirm that the bit setting for the ECM for fax on the MPC3001 same as the MPC4501A.

Thanks
