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.
Part information:
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.
Part information:
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.

Error 350 - how do I fix this?


error 350 means a disconnection, from your machine to that of the remote fax machine. Disconnection can either come from a power shortage, defective or not so good telephone lines, a call-waiting mode on the telephone, a defective fax machine or manual interruption.

However under rare conditions incompatibility between the two machines may cause the remote machine to simply get this code.
Try these steps...

1. Press setup, and then go to TOOLS.
2. Press okay on TOOLS, then look for RUN FAX TEST. Then press okay.
3. It will print a fax test page. Check if everything passed.
4. If it passed everything, try to press setup again, and then go to ADVANCE FAX SETUP.
5. Scroll, down and look for ECM (Error correction mode), then press okay
6. Under ECM you will have to options "ON or OFF" try to choose OFF then press OKAY.
7. Now, try sending a fax.



Also you can try to reset the printer.
1. Take out the cartridges from the unit .
2. Make sure the unit is connected to the wall jack directly without any surge protector.
3. Unplug the power cord from the back of the unit ( without turning off the unit ) .
4. Now press the # and 6 key together , while holding these keys down plug in the power cord back into the unit .
5. Do not release the keys after a few seconds you will find the hp logo or bars moving across the screen .wait while the unit turns off.
6. After one minute turn on the printer . It will go into alignment phase > let it finish .
7. After its done > try to make a copy .
Note - you can also try the OK and CANCEL key combination in place of # and 6

Fax does try and send but then stops and prints an error page err 388 each time?


The remote fax machine might be defective.

Solutions
  • Try to verify this by sending the same fax to other fax machines. If these transmissions are successful, then notify the user of the remote machine to make them aware of the issue.
  • If the fax fails when sending to other machines, turn it off for 10 seconds, turn back on, and then try sending again.

If you need more help come back.
