Check to see if your phone operates on the same jack the printer is connected to. Is comcast your telephone service or internet provider? You need to have a landline phone service or VOIP for a fax to work.

Since you have a DSL ( Digital Subscribers Line ), the HP Fax printer works on Analogue Signals.

To make the GP Printer work on Digital line, First step you can do is to Reduce the Fax Speed from Fast/Medium to SLOW.
To Do so, Click on Setup button on printer front panel - Choose Fax Settings - Choose Fax Speed - Set it to Slow and try to fax

If this does not work, you will have to connect a DSL Filter ( this is a 2 way port - 1 port for Digital line and another for Analogue )
You will have to connect this Filter to DSL Phone line - in the IN port and from the Analugoue Port - Connect Phone cable to Printer Line 1 EXTN Port at back of Printer

Will not send a fax


There is two things i can think of that can cause this. The number one is if you are using a voip carrier (like vonage or att voip or comcast digital voice) they are usually not compatable with fax machines. You will need either a dedicated fax line or you will need to whats called a fax line from vonage or comcast, or from your voip service. If you are using a phone line test to make sure you have it connected correctly buy simply dialing your cell phone or a friends cell phone (let him know you are going to test) once you do this you will hear a ring and an annoying fax machine tone buzzing in your ear. if this is the case and you do have everthing connected correcly i would put a trouble ticket in with your phone company, to test the line condition of your line (to make sure its not shorting or anything like that)
i hope this helps if there was more information i could do better but hopefully this will help out a bit.
Thanks

I can not send or recieve faxes. Ran fax test


Cox Cable is pretty much the same as comcast's and vonage's services. HP fax machines have had HUGE compatibility issues with those types of services, and may be that they did something to their service that caused your fax to stop working.....

Other than that call HP and see if they have any troubleshooting or Diagnostics that you can run, but I ran in to these problems with HP faxes all the time while installing comcast phone service, never knew WHY it didn't work, just that HP doesn't work on that type of service.....at least certain models...Also maybe call COX and see if they did anything recently that could cause it to stop working....

Someone is faxing me iam getting commerror283 how to fix it


This error typically indicates a problem with the line. Sometimes it's caused by noise (like from DSL on the same line, or alarm systems/home automation systems that use the same line).

Try other devices on the line, like a standard phone or modem and see if you can detect the noise issues. You may need to order a separate POTS line for faxing, especially if you are using the aforementioned services or VoIP systems.

Hope this helps!

Sending faxes


I believe if you have comcast it is a different signal coming in, you probably bought the package for VOIP capability when Comcast was having that promotion. The phone has to be a regular analog phone line not digital, that is probably your problem. Try changing the settings or line it should solve your problem, or call Comcast to guide you along. Cheers!!
