Question about HP LaserJet 2840 Printer
It can be a defective fax module or formatter, but most likely, it is a software issue.
Make sure you have the latest firmware.
When/if firmware is the latest version and problem persists, go to Menu -> Service -> Restore Defaults.
If problem persists, it might be a good idea to try a different land line, if you have one available, before purchasing new hardware.
Please note you need a different board depending on which region of the world you live in. I'm assuming North America here.
The fax module for the 2840, is about $27.31.
Q3977-60011 - PC Board (Interface) : Line interface unit (LIU) PC board - Telephone interface board for the printer.
If the problem is in the formatter (main board), the price goes up to $405.65. Please not, that the LIU (fax module) is included in this.
Q3948-69006 - Formatter / LIU assembly (for North America) - Includes the formatter PC board, the line interface unit (LIU) PC board, and the metal card cage.

4. Now press the # and 6 key together , while holding these keys down plug in the power cord back into the unit .
