Question about HP Officejet Pro L7780 All-In-One InkJet Printer

3 Answers

Our new HP Oficejet Pro L7780 can send faxes but can't receive

We are on wireless for our printer. The HP L7780 is connected to power, phone cord (using our extra long phone connector as theirs was WAY too short), and a router to print wirelessly. We are a small business office and I can't seem to find any help, manual, directions. I need help!!! Help us receive those faxes. You are the Master

    Our fax line is the second line in the hunt so there is a line share device on the line (The Stick). Our phone vendor tried a different line share device but still had the same problems. (1) The fax takes forever (4-6 rings) to pick up even though it's set to 2 rings, (2) when it does work, which is rarely, we might get 1 or 2 faxes then can't receive anything. The sender hears ringing but is eventually disconnected. Both our service provider and phone vendor have been here trying to resolve the issue. If the vendor technician plugs in his test set it does ring when his office sends a test fax. However, if he then plugs the fax in, nothing happens. Any ideas???

I have a problem that it fails the 'correct type of phone cord' test. It tells me that I need to use the 2 wire phone cord adaptor with my existing phone cord.

I too have a problem with HP7280. I can send faxes but not receive. I am using Cox digital cable phone service and have one phone line for phone and fax with distinctive ring for faxes. HP technical support tried test fax and he himself heard the distinctive rings. He basically ended call saying sorry but HP has problem with incoming digital phone fax signals and he had no solution.

Any ideas for solution with this model? Or do you know of any all in one combos, perhaps another brand that will work with digital signal?

Hi,

First things first, i really want to know how things being setup in your end. Let say for example, from the walljack what is the device connected to it. Or if your using one line for both incoming calls and faxes. Or if your using a DSL also for that same phone number for faxing/incoming calls.

Those are just severa factors that affect your problems. Meanwhile, i cant give you a solution on your issue since i still dont have a clear picture on are the devices connected with each other. ALso, its really advisable that you need to use the telephone cord that came out with the box.

Thank you so much. I remain.

L7780 is not receiving FAXE'S. Only Some of it ??


This is strange. Sounds like noise is in the line. Try searching the line for bad spots or replace the line. The ends could have corrosion on them also. The wires are most likely copper and the corrosion will be green. Check the box on the side of your house also. I would have the phone company check for noise in the line for you. Good luck.

I have an HP L7780. We are having an issue receiving faxing. The pages are often only 1/4 complete. There is no reported error. It doesn't happen all the time.


Send a fax on this number
1-888 HP FAX ME (1-888-473-2963)

and see whether you receive a fax from hp or not whenever HP receives a fax from any number it sends back a fax to prove the functionality you can say.

the reason behind reviving the 1/4th fax can be fault at sender's end

Disconnect the power cord from back of printer ( when printer is powered on )
Hold the # and 6 button and while holding connect the cord back

This reset will Erase fax logs, wireless connectivity any other memory stored in printer

Follow the instructions on printer screen to re-align the printer and cartridges

Try to send/receive fax and it should work.

Can't receive a fax


There are some settings that you need to change.

You need to turn off the following:
Error Correction Mode

to get to these options you need to go to the setup menu by pressing the setup button
then scroll to advanced fax settings and select it and you will find the options listed under it

You also need to check the fax speed under Advanced fax settings.
set it to medium.
hope this will help you :)
