Call the fax line with your cell phone, does it pickup the line.

I have always a simple corded analog telephone with some adapters/fax cables in my company car for issues like. It's a simple but effective check of the analog line.
Have you checked the line?
Machine is in automatic fax receive mode?
If you call the fax no does machine hang up?

Re: Ricoh MP2851 cannot receive fax message

call your cell phone from the fax and check the caller id to make sure it is the right number. They may have had some recent phone service and now their "dedicated fax line" is no longer on the phone number they think it is.

Hi Anothertech,

I call the fax line with the mobile phone can hear the ring tone then later the fax tone so it not the problem with the line. The fax is set to autoreceive mode on the copier.

Are you standing in front of the 2851 so as to confirm that it is the machine that is answering? I have had customers who had one or more old machine elsewhere in the building connected to the same line. They had done this so that the other locations could fax out. Worked fine as long as none of them were set to answer.

Re: Ricoh MP2851 cannot receive fax message

You mean the FAX is not picking up the incoming ring tone ? AKA a deft FAX.
I assume the line is a single ring tone FAX line with out DUET.(ie. Two distinctive ring tones on the same line) ?
Telco line/cable attenuation may have changed.
If you plug a manual hand set into the FAX line and the line is clear with out noise/sperry,
then it might be an impedance matching problem the physical line.

Is the fax received all okay but being storing to secure memory for later manual print out ?

The ring you hear is generated at your VOIP modem card and/or the the phone company central office. It's a misconception to think that the ring you are hearing is generated by the receiving fax, It is not. If nothing was connected to the line, you would still hear a ring.

In a situation where you have as many as (4) faxes connected to the same phone line, yes a fax will answer, just not the one you are standing in front of. It's a fax Rx lottery: which fax can pick up faster?

Back to the analog handset: It's fully possible that A) the line at your end never rings or never rings in a way the fax recognizes, or B) that you are experiencing one-way communication. In either case you won't know anything until you connect a handset and dial a call, and receive a call.

Customers do this all the time: blame the fax machine when 95% of the errors occur in the lines. Find out if the lines are working first. =^..^=

Re: Ricoh MP2851 cannot receive fax message

Did they recently switch to voip, if so you may want to try these settings:


ECM: 1-104-002 (com. swich 1) change bit 0 to 0
Cable EQ Settings: 1-105-008 (G3 switch 7) change bits 0,1,2 and 3 to 1
V.8 Protocol: 1-105-004 (G3 switch 3) change bit 2 to 0
Modem Speed TX: 1-105-006 (G3 switch 5) change bit 0,1 and 3 to 0. Change bit 2 to 1
Modem Speed RX: 1-105-007 (G3 switch 6) change bit 0,1, and 3 to 0. Change bit 2 to 1

Re: Ricoh MP2851 cannot receive fax message

check whether the reception file setting in facsimile features was set to store instead of print.
check parameter setting switch 10 bit 5 whether or not to print store received documents, 0 for off and 1 for on
check parameter setting switch 11 bit 6 whether to print or store the incoming fax , 0 for off and 1 for on

Re: Ricoh MP2851 cannot receive fax message

Had a 2851 last week that could receive, but could not send. Tested with my handset, ok.
Line "sounded ok", and I could call out.

I plugged their MP 2851 into another phone outlet(different number) and it worked.

Turned out their phones ( using cable modem) needed to be reset.

Yes we are starting to see similar problems like the above.
Our entire country is being "FORCED" to go full digital telecoms line. No more audio error free happy analogue phone lines. We are all being force to change our analogue phone line over to "National Broad Band" which IMHO has been a total step backwards in technology. The phone audio sinpos's in an out with broken voice clips and chirps, exactly the same as Delusion Digital TV.

"WHAT A STEP BACKWARDS THIS NATIONAL MONITORING BROAD BAND INTERNET GARBAGE IS.

At least we'll have more problems to fix. Works out as a positive for those on do-n-charge wage rate.

Re: Ricoh MP2851 cannot receive fax message

A little after the fact now, but back in the day when analog lines roamed the Earth (along with the dinosaurs), I had an issue where we replaced about a dozen Canon MFPs with Ricohs.

All machines had fax boards in them.

The Canons always worked (well, almost always), but about half the Ricoh machines refused to answer; they all sent just fine.

Turned out that the incoming ring voltage, which should be about 90 VAC or so, was too low (maybe about 85), and the Ricohs refused to answer.

The customer worked with their telecom provider to resolve it.

All of our multi machine accounts are doing this for cost reasons.

I tell my customers if it really matters that you faxes go through soonest use analog lines. =^..^=
