Question about HP LaserJet 2840 All-In-One Printer

1 Answer

Out going faxes some go through and some don't.

Some give me a busy sig. and others go OK I tried calling the same number from a phone at the same time it was ring busy and I get through.
this tells me that the machine is not connecting. It is a line with DSL on it.
I recently added filters they supplied but it made no difference.

Filters will not cure your problem. ALL fax machines are ANALOG devices and will not work on DIGITAL phone lines.

All my faxes say busy


It is not uncommon for this to happen. What I did with my Pixma was go on the assumption that the fax executable file had become corrupted. So I uninstalled it, then reinstalled, and all went smoothly until the next time, when the same solution worked again. Since the other possibility is hardware which means money, try my solution.

I am getting rid of my dedicated fax line and am adding it to my land line. I am told when I have a fax coming in I will hear a double ring which mean my fax line is ringing. How do I set my fax to...


There are two ways to configure a fax machine to answer the phone line. The first way is by pushing the "auto answer" key on the keyboard of the fax itself. When this key is used, the fax machine answers all calls that come in after a certain number of rings. The other way is to manually press the fax button when an incoming call is happening. You can set the number of rings for your machine to pick up by using the keys on the fax machine under the menu feature and then scroll using the up and down arrow keys until you see fax set up and then number of rings.

I have heard about the option that your speaking of, where they give you a separate phone number for your customers to fax when you own a business line but I don't know how the fax machine itself would be able to distinguish between the normal ring of a regular call and the double ring of the merged fax line call. I was told that when I set that up for my friends business recently, that the machine would auto recognize the double ring without any programming and to use the auto answer feature for all calls. He has not had any faxes yet (its a new business) so I can't say for sure if it works or not? I can say that none of his regular calls have been picked up by the fax so far though.

WE CANNOT RECEIVE OR SEND FAXES, BUSY/NO SIGNAL


Plug a phone into the jack and check to make sure you have a dial tone. If not telephone company needs to be called. If dial tone it may be the other number you are trying to fax to. try calling the number from phone and see if it picks up.

We cannot receive faxes. Gives a busy signal.


Unplug the phone line from the machine. Wait a few minutes then try calling your fax number from a phone while leaving the phone line disconnected from the machine. If it rings fine from the phone, then re-install the phone line to the fax machine. Try making the call again. If you now get a busy signal then the modem in your fax machine has gone bad and is holding the line open. Make sure when installing the phone line you are placing the cord into the "line" port on the machine and not the phone port.
Good Luck and thank you for using Fixya.

Companies trying to fax to our office tell us that our fax number is "BUSY" but the faxes we receive "failed" and nothing is printed.


Take a cell-phone, and dial the telephone-number that you are giving to your customers. Does it ring? Does the FAX "pick-up" the call?
Or, do you get a "busy" signal?

Ricoh 1013F Fax Line answering phone calls


Not quite sure the Ricoh has what is commonly none as a fax switch. This actually catches the call and looks for the fax tone from the sending fax to determine if it is a fax or not. The Ricoh can not determeine what number is dialing in. It only knows a call is incoming.

You can ourchase a fax switch online or Radio shack had them.

Busy/No Response


Using a cell phone, call your fax machine to see if the fax answers. If it does answer, then hang up the cell phone and fax. Next, using the HOOK button on your fax, call your cell phone . The cell phone should ring and answer the phone call from the fax. If you do not get a connection between the fax and cell, try these: Check that the phone line to the fax is plugged into the LINE jack on the fax, NOT THE PHONE jack. The PHONE jack on the fax is to plug in a TELEPHONE ONLY. If the fax phone line is OK, go into your fax machines' RECEIVE and SEND settings and make sure they are set up properly (pulse or tone dialing, overseas mode, etc.) Print out the HELP LIST as follows: Press MENU button, then 5 on keyboard, then 1 on keyboard. Go through all the settings on the HELP LIST that apply to your problem. (Send and Receive modes, Ring Delay, Receive Options,etc.) Write down the original settings BEFORE YOU CHANGE ANY OF THEM.

Fax problem


unplug the fax from the phone line. call it from you cell.if you hear your phones ringing in the house, plug the fax machine back into the jack. [you should still be on your cell phone] if the line goes dead or stops ringing, there is a short with the fax machine or wire to the jack.if you hear a busy signal without the fax plugged in, unplug everything you have plugged into phone jacks thruout the house. call your # again.if you hear ringing on your cell phone, plug everything back in one at a time.[again while still on your cell phone] if it was one of the phones plugged into a jack, when you plug the shorted phone back into the jack, the line will go dead again. that phone or cord is the problem.
if still rings busy when everything is unplugged, then call your phone company. it can be an inside wire or jack problem, or the problem is outside your home.
hope this helps
