HP Officejet 7210 All-In-One InkJet Printer
Error code: 405

When I send a fax I have a dial tone and the fax feeds through, I hear the other end answer it says it is sending and then I get the printed page that says: "A communication error occurred during the fax transmission."

I also was not able to copy, scan or fax multiple pages through the ADF of our HP Officejet 7210 AIO, but it would print well from our computers.

It would either grab several pages at once, or not grab paper at all. The feeder was trying but had poor traction action. Not sure if that's the same situation for you, but this is what fixed ours:

I purchased part number C7309-60091 feed roller assembly, and part number C7309-60076 separation pad from Encompass Parts, and replaced them. The ADF works great now.

Our HP Officejet 7210 had only 3,000 pages printed on it, which didn't seem like enough to wear out the separation pad or feed roller in the ADF, especially since all those pages didn't go through the ADF, so I figure it's because of our very dry environment. Hope this helps you.

Hi,
It can happen due to sensor problem ,please try a power reset if possible and then try again.
