When I send a fax on my Officejet 3830 the printer dials, connects, but then I get error code 388. Research says error is due to bad line but don't have error with phone dial to same number.

Hi @underdog38,
I'd like to help!
Error 388 indicates too much noise on the telephone line is preventing a valid connection between the fax machines. Retry the fax when line conditions improve
Meanwhile, print a fax test report and share the results
On the Fax screen, touch Setup , touch Tools , touch Test Fax , and then follow the on-screen instructions. The printer displays the status of the test on the display and prints a report.
Hope this helps! Keep me posted.
