I can send faxes anywhere; no problem. When the printer attempts to receive a fax, it seems unable to shake hand, connect or whatever with the incoming call (?) I get the message fail to receive. The telephone line has a dial tone. I use one line for faxes, another for telephone. Everything else works. Print, scan, photocopy and "send fax". Any suggestions?

I've seen this many times before, when a customer / account gets a new fax machine, or is using a different fax machine. All the other faxes go through without a hitch, except for these. If fax machines become a couple generations apart / 10 years, they won'
t communicate sufficiently enough to make the fax hand shake and the Fax fails to go through.
The receiving product has been unable to receive an entire page even after multiple attempts to rereceive the parts of the page that contain errors. This is usually due to extremely poor line conditions.
1. Reattempt the fax reception at a different time when telephone line conditions have improved. 2. If the error persists, disable ECM. Errors may still occur, and may result in degraded image quality on the received page. However, the ability to receive the entire document will be improved.
Error Code 420
V.34 negotiations have failed from the originating product during phase four, which occurs after V.8 and before the first T.30 frames are exchanged. Compatibility problems have been observed in this area when sending to non-HP units.

This means that an error occurred during transmission after one or more partial pages were sent. The sending machine was unable to restart the control channel connection(handshake) before sending more data. This error typically occurs when the receiving fax disconnects after receiving part of a page. It can also be caused if the receiving fax is using a fax format incompatible with the HP fax (usually during color faxing) or the line speed drops to an unacceptable level.
Check that the phone cord is plugged in correctly and is not cut, creased or damaged.
Make sure that the phone connection terminal box is not damaged and that the cable connecting to it is not damaged.
Try the fax at a different time when telephone line conditions have improved.
