Question about HP Officejet Pro L7680 All-In-One Printer

HP L7680 All in one will not send faxes from PC S/W interface

I have 3 networked PCs, 2 of which can use all the 7680's features from the S/W interface. One PC can do everything but send a fax through the "Solution Center." Printing works, scanning works, the network is fine, the fax setup test passes fine, everything looks good. When scanning a page to fax, the scan works and then it simply says: "The fax could not be sent. The fax will be moved to the fax log where you can resend it."
I was on with HP tech support for 2 hours 40 min., and we ended up reinstalling the entire 7680 software suite. Everything installed fine; still no dice trying to send a fax through the S/W interface. Faxes work fine diretly from the device, and from the other PCs. This is bizarre - any help would be appreciated.

Re: HP L7680 All in one will not send faxes from PC S/W...

After much thrashing, here is the solution to the problem. Somehow the printer drivers lost coordination with the corresponding Windows supporting programs. You would think that reinstalling the printer drivers would fix the problem, AND IT DOES, but there are 3 tricks:

· Uninstall everything associated with this printer with the install disk in the computer (this may really not be necessary, but it worked for me). [This is also the solution when the a window comes up asking for TrayApp to be inserted using a disk—they mean the hp install disk].

· After the un-install, MAKE SURE you ALSO delete the printer using the control panel. This is critical. If this doesn’t happen, the corresponding Windows software is somehow hooked to the wrong thing when the reinstall happens. Then reboot the system.

· Install the new drivers with the printer off, and the USB disconnected from the printer. Reboot the system [not sure the reboot is necessary]. After the computer has booted, connect the USB, and power up the printer. The computer will recognize the printer and put the printer icon in the Control Panel.

It turns out that correcting the driver mis-coordination by BOTH uninstalling the printer drivers and taking the printer out of the control panel, then properly reinstalling solves BOTH the fax problem, and the protection fault problem! Amazing such a little thing can make such a difference!

You can start a scan from your computer or from your HP PSC. 1 Load your original.
2 Press Scanner, then press PC Save, if not already lit. This saves the scan to your computer.
3 Press Black or Color. For Windows, a scan of the original appears in the HP Image Viewer. For Macintosh, a scan of the original appears in the HP Workplace. In the HP Image Viewer, you can edit the scanned image. When you are done viewing the image, click Accept.
The HP PSC does a final scan of the original and sends the image to the HP Photo View Center in Windows. In the HP Photo View Center, you can:
- edit images, including adding text
- creative printing
- create and print photo albums
- send to fax, e-mail, web page, or other programs.

Fax machines are sorta like printers, sorta like scanners, and sorta like dial up modems all wrapped into one expensive box.
1. First thing to make sure of is that you are hooked to a phone line. most fax machines have a phone handset that you can make calls from. Call someone and make sure that works. If So, you are able to connect to phone networks, and should have no trouble sending or receiving data. If you have a dead line or no sound, check the line and check the power. (its always the easy stuff that is overlooked, just check it and make sure).
2. If this fax machine has computer interface, (usb port or parallel cable port), see if you can scan with it. Drop a document into the scan area and see if the computer can scan an image from the scanner. If the scanner works, you can scan images into the fax machine to be sent to the fax number. (If your fax machine does not have a scan to computer feature, skip this.)
3. if your fax machine has a print from pc feature, try to print a document to it from your computer. If you can print, then the printer works, and you can receive faxes. (if your fax machine does not have a pc printing feature, skip this)
4. Here is how a typical fax machine works. You place the document or image into the scanner feed area. You press a big button that usually says "fax" and then, a screen pops up saying to dial the number. You dial the number and press SEND. once you press Send, the machine will scan the document, dial the number and sing a little dial up modem song awaiting a response from the receiving machine. the receiving machine acknowledges the fax, and the singing is no longer audible (but it continues because the modem song is actually data transmission/reception). after about 20-60 seconds, the fax completes and the call ends. As for the particular model you have, the functions should be about the same, though the buttons and arrangements may be different. FYI, you can send a fax straight from the PC too, if you have a dial-up fax/modem card.

My officejet pro L7680 does not receive fax. The ring setting is for 3 rings and the little green light is on the auto answer switch. It sends nicely.

Since you can send faxes, it's not the phone line or cord. It's most likely that you have the "distinctive ring" option set to something other than "all rings", check that first.
