Why doesn't my fax machine print the received faxes?

The fax machine may be in secure receiving mode. The following is from the User's Manual section on Faxing. downloadcenter samsung com

Receiving in secure receiving mode

You may need to prevent your received faxes from being accessed by unauthorized people. You can turn on secure receiving mode to restrict printing of received faxes when the machine is unattended. In secure receiving mode, all incoming faxes go into memory. When the mode is deactivated, any stored faxes are printed.

Activating secure receiving mode

1. Press (Fax) on the control panel.
   

2. Press Menu until Advanced Fax appear.
   

3. Press the left/right arrow until Secure Receive appear and press OK.
   

4. Press the left/right arrow until On appear and press OK.
   

5. Enter a four-digit password you want to use and press OK.
   

   You can activate secure receiving mode without setting a password, but cannot protect your faxes.
   

6. Re-enter the password to confirm it and press OK.
   

7. Press Stop/Clear to return to ready mode.
   

When a fax is received in secure receiving mode, your machine stores it in memory and shows Secure Receive to let you know that there is a fax received.

make sure the property settings for the fax are not on the Microsoft printer make sure it is set to the local usb printer

Does the machine print anything? such as a directory or print when making a copy? I rather suspect it does not. When an incoming fax is recvd does the paper get pulled in and come out blank? If so your problem is with printing (or lack of it). Perform head cleaning. Also make sure the black cartridge still does not have its deal stuck on it. Post again if you still have problem.

This means that your fax is only storing into its internal memory and not printing all incoming faxes, therefore it has no more space for more incoming documents, you should print the documents and maybe you'll need to clear the memory, depending on fax machine, this is done automatically when the documents are printed, and of course, set the incoming faxes to print not to store, this feature is supposed to be used only when the fax has no paper to print.

First, does the machine print normally from a computer or when making copies?
If so, then most probably you have enabled a private receive fax mode. In this mode, faxes are not printed immediately upon receipt (to prevent unauthorized people to read them), but are stored in memory, waiting for an authorized person to come and print them, providing a PIN (password).
To print the faxes stored in memory, do the following:
- press FaxMenu
- using arrow buttons select "receive"
- press OK
- using arrow buttons select "print faxes"
- press OK
- using the alphanumeric keypad enter the PIN/password and press OK
THe previously received faxes should print..
SOmeone must have turned this option on, so ask that person what he/she entered as the PIN.

Issue: ERROR LCD: WAITING FOR REPORT
Solution: Set [AUTO PRINT RX] to ON (MX300 / MX310)

AUTO PRINT RX When [AUTO PRINT RX] is set to [OFF], incoming received faxes will be temporarily stored to memory and transaction reports (TX, RX and Activity) remain in memory. The default setting is [ON], which means incoming received faxes and transaction reports will automatically print. The fax machine will not automatically print a received fax and will store it in memory in the following conditions.

• Ink is low or has run out
• The paper size and type is not set correctly
• Paper has run out
• The Output Tray is closed

To set AUTO PRINT to ON, please follow these steps.

1. Press the <FAX> button to enter the Fax menu.
   
   
2. Press the <Menu> button. [FAX SETTINGS] is displayed
   
   
3. Press the left or right arrow button to select [RX SETTINGS] , then press <OK> two times.
   
   
4. Press the left arrow to select [ON], then press <OK>.
   
   Note: When AUTO PRINT RX is set ON, a sub-menu will appear to PRINT WHEN NO INK.
   
   
5. At sub-menu PRINT WHEN NO INK, decide if you'd like the machine to continue to print incoming received faxes if ink is low.
   
   CAUTION: When this option is set ON, the fax machine will not monitor the ink level of the ink cartridges. If ink is low or out, received faxes will print with streaks or blank. Furthermore, once the fax is printed, it will be deleted from memory.
   
   1. To print received faxes when ink is low or out, press the left or right arrow to select [ON] and then press <OK>.
      
   2. To store received faxes in memory when ink is low or out, press the left or right arrow to select [OFF] and then press <OK>.
      
      
6. Press the <Stop/Reset> repeatedly to return to Fax standby mode.

Has the main board been changed??if yes the liu board(modem) board needs replacing.

Incoming faxes automatically go into memory. We can't print them out. Would like incoming faxes to print out as they used to. have tried the on off button but it didn't fix the problem

If you press the on /off button once the machine will switch to auto print on,if you keep the on/off button in the machine will switch on or off.
