Ricoh 3310LE Fax shows error 0500H display

I've never seen a message like that with the 0390H code. There is no mention of that code in either the user manual or service manual. The closest thing is the sc390 code, which means either the toner density sensor or the developer has gone bad, and typically replacing the PCU can fix that problem.

If the new PCU doesn't fix the problem, you might want to try calling Ricoh for support, since their documentation doesn't mention that code.
tip

Whirlpool duet F70 and F71 error codes.

F70 and F71 are two logic board error codes that point at a communication error between the main logic module and the control pad (user interface and CCU), and between the motor control unit and central control (MCU, andd CCU that is main control module).
Repair is difficult, as motor, wiring and voltages from control modules must be tested.

Try first doing a reset, by disconnecting power cord or tripping circuit breaker and leaving power off for five minutes.

If that does not help and errors come back, then the best thing to do is calling the service number listed on the user manual.

Here extensive explanation of error codes and relative troubleshooting:

F70: CENTRAL CONTROL UNIT HEARTBEAT FAILURE
If a Central Control Unit Heartbeat Failure is displayed, no communication is detected from the Central Control Unit to the User Interface.

1. Check for continuity of the User Interface harness.
2. Check wire harness connections to the User Interface and the Central Control Unit.
3. Replace User Interface if drum is rotating.
4. Replace Central Control Unit if drum is not moving

F71: USER INTERFACE HEARTBEAT FAILURE
If a Central Control Unit Heartbeat Failure is displayed, no communication is detected from the User Interface to the Central Control Unit.

1. Check for continuity of the User Interface harness.
2. Check wire harness connections to the User Interface and the Central Control Unit.
3. Replace User Interface if drum is rotating.
4. Replace Central Control Unit if drum is not moving.

We keep getting an error code 344* when we are trying to transmit a fax. What can we do to fix this?

Error 344 means :-

The remote machine has failed to respond to a fax command from the product because the connection is interrupted.
The remote user has pressed the Stop button while the remote machine was receiving.
Under rare conditions, incompatibility between the two machines can cause the remote machine to simply abandon the call.

Solutions :-
  1. Attempt to send the fax again when telephone-line conditions have improved.
  2. If the fax session was using error correction, disable ECM.
To disable ECM Press :-
  1. Press Setup .
  2. Press the Down arrow (c00326489.gif ) repeatedly until Advanced Fax Setup displays.
  3. Press OK .
  4. Press the Down arrow (c00326489.gif ) until Error Correction Mode displays.
  5. Press OK .
  6. Press the Right arrow (> ) until either OFF or ON displays.
  7. Press OK .
  8. Send another fax to verify that the ECM is enabled or disabled.
Check the Phone Cable connected with the printer.
Make sure the Cable should be connected to line 1 port at the back of the printer and it should be going directly from the printer to the wall jack and not to the Serj protector.

Try to print a fax test page.
  1. On the control panel of the product, press the Setup button (c01361401.gif ).
  2. Press the Right Arrow button (c01185072.jpg ) to select Tools , and then press OK .
  3. Press the Right Arrow button (c01185072.jpg ) to select Run Fax Test , and then press OK . The product displays the test results on the control panel display and prints the Fax Test Report.
Now Do this :-
  1. Send a one page black and white text fax to 1-888-hpfaxme (1-888-473-2963).
  2. When your fax is received by the HP Test Fax Service, we will generate a return fax to you within five minutes confirming that we received your fax. This verifies that you can both send and receive a fax with your fax machine.
If you do not receive a return fax within 5-7 minutes, there may be a problem with the setup of your fax machine. Consult the user manual that came with the product for proper setup and configuration. Try the above steps and let me know if it works for you.

The remote fax machine might be defective.

My canon mp500 is displaying error code 6400. the alarm, and copy light are flashing. the usb cables are connected.the manual has no error code 6400 listed. please help me

That error indicates a problem with the sheet feed unit. Unfortunately this is not user fixable and will require you send the printer to Canon's Authorized Repair Center (for your local area, you will find it easiest to locate this via Canon's website).
