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