My Canon MX420 jumps from "copy" to "fax" with the fax memory light always on. How do I clear that?

SOURCE: how to clear the memory

Press FUNCTION key then 9 key. The display will ask you to ENTER FILE NO. OR ^. You want to enter ### as the file number and press SET to delete all files. (You cannot delete the file while it is being sent). The display will then show DELETE ALL FILES? 1:YES 2:NO. Press 1 to delete all files.

SOURCE: fax memory

This thread might be dead but I found that you CAN turn off report printing, which also frees up the memory, in the Fax->Menu->Maintenance/settings->Device Settings->Fax Settings->TX Settings->TX Report. Turn reporting off and it clears memory also. Hard to find but its there.

SOURCE: On my Canon MX310, the display says

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

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.
