I also own a HP 7580 multifunction fax and if I hook it up to the same line, it has no problems and never loses a fax.
This appeared to me at first to be a defect in the particular M2727 I had so I returned it for another.
New machine does exactly the same thing. I have turned on "Silence Detect" but it has made no difference.
Again, same line, same faxing parties, one machine works reliably as it should, one doesn't.
I am going to lose customers over this if I don't get it figured out quickly. Any ideas?
Thanks in advance!

Bought a M2727 to replace a HP Laserjet 3330. While the fax on the HP 3330 was working fine, no faxes are coming in on the M2727. The machine that sends the fax gets a 'no anwer' report.

On the HP 3330 we also had a three year care pack and that served us quite well. It had two hardware problems which HP took care of within one day.
Now however the care pack had run out when it started giving some trouble again. That's why we replaced it.

I have the same problem with M2727 (Warsaw, Poland).
Before, I used HP3880 on this phone line without any problems.
I sent M2727 to HP service and they replaced some electronics parts but it still doesn't work.

I have a VOIP line for my fax (Vonage) any suggestions?????
04-18-2008 09:05 AM
Unfortunatly this is a very common error on this particular printer itself.
First off that cold reset the other person suggested and instructed to do is not very well to do on your printer.
It basically erases everything in the printer. brings it back to factory defaults.Erases the serial number in the printer
and rarly ever works. We use this as a last resort.
I will give you some troubleshooting steps you can do to fix your printer. The same steps you would get as if you were to contact tech support.
If you are recieving comm errors.
print off a error report.
beside the comm errors with be a 3 digit number
if you go on hp.com and in the search box type in "comm errors" your able to view what these errors mean.
Sometimes all it is, is insufficient amount of power. or even a bad telephone line.
These printers are very picky, one thing i sugges is phoning the fax line on a regular telephone and listen to static. it might even not be noticable you can contact your phone company and get a sweeper signal sent over the line to clean it out.
Some of the settings you can change on to help these problems, such as comm errors and no fax detected are as follows.
Hit the setup key
go right till you find fax setup
go right till you find all faxes
you will see Error Correction
hit the right arrow key to turn it OFF
brings you back to fax setup > error correction
go right till you find fax speed
its defaulted to full
hit the right arrow key change that to medium
these settings are not going to harm or effect anything else on yur printer
there just going to slow it down a bit allowing the printer to hopefully easily connect over the telephone line.
another thing to check is the phone cable.
They do come with telephone cords that i know are somewhat to short. So you use antoher one. We want to make sure it is a 2 pin cord, most cords are 4. To find out, take the phone cord out of the jack, look into the clear plastic piece and you will see colorfull wires, you only want to see 2.
This is also going to cause communication errors. because signals are going to be lost in 2 of the pins that arnt being used. Thus giving you communication errors or no fax detected.
Next you can do is a soft reset on the machine. These will change all the settings back to default and erase anything saved in the printer such as a phonebook. This does not harm the printer in anyway
hit the setup buttons once
hold down the right arrow key
while holding down the right arrow key
hit the cancel button once
it will go back to ready thats ok
hit the setup button again
if you did it right it should say developpers menu
hit ok on developpers menu
go right untill you find "REINiT FFS"
this is going to bring the printer through some resets. it wil flash beep and the screen will say permanent storage init.
it will power off and on thats ok. wait till it comes to ready, reset all your settings if have necessary ones and try fax again.
the settings you want to change on your printer to get this to work. ( it may not work, our fax machines do have a hard time working over this kind of line )
Change the Baud rate :
your going to want to hit setup
then hold down right arrow
and while holding down the right arrow hit cancel
hit setup again
display should read developpers menu
if not keep doing it till you get it
once you see developpers menu hit ok
go right till you find "R/W Parameters"
enter 153 on the number pad
display should read "T30XMIT RATE"
then press the numbers 16 on keypad
then press enter
this wil change your baud rate which will help out on a VOIP service
Another setting to try is changing CNG Tone Min count
>>> press setup
hold down right arrow key
while holding down right arrow key, hit cancel button
hit setup again
should say developpers menu
go right till you find "R/W Parameters"
Go right till you find " CNG Tone Min
enter 3 on the keypad
then press cancel to exit developpers menu
Hopefully this will help you out a bit.
If you do have questions there is tech support available at
and go to laserjet department
If you do have any more questions i do get notified when there is replys, so maybe i can help a bit more.

The bug is strange: when press send fax button device not invite "send from glass" but goes to "receiving" or simply not reacts on pressing. If load the document and press button there is no dialing too, but the task saves and sending may start later, for examle with unplug the cord and plug again!
Sometimes helps the change of cords (both 2 pins similar length!!). I know that our PBX has low voltage on its extensions (about 20-21 volt) therefore problem maybe with physical parameters of line, something is on "threshold". Maybe there in developer`s menu is some useful settings for this problem?
P.S. other MFPs, analog fax-machines work correctly with our lines!

My M2727nf seems to have problem receiving fax also with the "No Fax Detected" error. I tried the suggestions from one of the posts above by turning off "Error Correction" and decreasing the fax speed to "Medium V.17", and that seemed to fix the problem. I was able to receive fax in "TAM" mode without problem, M2727nf was able to detect the fax signal after my answering machine picked up without any issue.
Anyway, today I reinstalled my printer driver with the latest one from hp.com, and during the installation process, it also updated the firmware to the latest version dated 1/18/2008. Just out of curiosity, after the firmware update, I switched all settings back to default. I turned "Error Correction" back on, and fax speed back to "Fast V.34". I tried receiving fax again, and to my surprise, the fax came through smoothly. Looks like the latest HP M2727nf firmware from 1/18/2008 might have fixed the problem!!!
Those of you still having the "No Fax Detected" problem, try updating your firmware to the latest version, then post your result here. Hopefully the latest firmware has fixed all of our problems.

HP usually has great LJ printers (well, at least anything not scraping the bottom of the price barrel anyway). So, I'll cut them some slack here.

Yes, I made that mistake for years. The only reason I checked is a friend mentioned it. And since I could FAX from the computer modem, I assume I had it connected properly.
