Failing to receive a fax it says received in memory but not printing even when I want to print. Could you please help

The in use alarm appears to be related to fax reception and printing. There are some options below that you could try:-
Memory Reception If the machine receives a fax under one of the following conditions, it will not be able to print the received fax and will store it in its memory. The In Use/Memory lamp is lit and Received in memory is displayed on the LCD. When the problem is resolved as described, the fax stored in memory is printed automatically.

• Ink has run out: Replace the FINE Cartridge.
  Routine Maintenance
  Note
  
  • You can set the machine to forcibly print a received fax even if the ink has run out.
    However, part or all of the fax may not be printed since the ink has run out.
    Also, the contents of the fax will not be stored in memory.
    If the ink has already run out, we recommend that OFF be selected for Auto print in FAX user settings to store the received fax in memory and print the fax manually after replacing the FINE Cartridge. After you replace the FINE Cartridge and select ON for Auto print, the fax stored in memory will be printed automatically.
• Paper has run out: Load the paper and press the OK button.
• A different size of paper from that specified by Page size is loaded:
  Load the same size of paper as that specified by Page size, then press the OK button.
• Page size is set to other than A4, 8.5"x11"(LTR), or Legal (or 8.5"x14"):
  Set Page size to A4, 8.5"x11"(LTR), or Legal (or 8.5"x14").
• Media type is set to other than Plain paper:
  Set Media type to Plain paper.
• You pressed the Stop button to cancel printing of a fax:
  Press the FAX button
  

Alternatively turn the printer off, open the devices and printers section of Control Panel, right click on your printer and select "see what's printing" and left click on this. A window will pop up which may or may not contain a list of documents. If it does these must be cancelled (Menu - Printer - Cancel all documents). Once all documents have gone from the list turn the printer on and try to print.
Other than the above suggestions I would need to know more about your OS and exact problem. Hope this helps.

Try this step ... found it on Canon's website

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>.

Dear guys, your toner cartridge is low and as a preventive measure, the unit stores the faxes in order to give priority to copying and printing. If you are using remanufactured cartridges, the unit might not be displaying the low toner warning.

TYPICALLY A FAX MACHINE WILL RECEIVE MESSAGE IN MEMORY WHEN NO PAPER OR TONER/INK FINISHED INDICATION IS THERE, REPLENISH THESE SUPPLIES WITH GENUINE ONES AND FAX WILL START PRINTING. IF PROBLEM IS NOT SOLVED , PLEASE TRY TO CLEAR THE SETTING FOR MEMORY RECEIVING, IF STILL NOT SOLVED TRY BRINGING THE MACHINBE TO FACTROY SET SETTING BY CLEARING THE MEMORY. HAPPY FAXING OMNIPRESENT
