Received in Memory issue

My faxes are not printing, they are going straight to memory. I also have this coming up on screen: Recommend new B-CRT, and Recommend new C-CRT.  What does this mean? I have not discovered this message anywhere in the manual.

    Our faxes are going directly into memory and I can't find anything in the manual to direct me to changing this setting so that faxes will come right through. Please advise.

    I have a Canon MX310 that now will not let me send or receive (?) faxes.  I keep getting a message that the memory is busy and "recommend a new C-CRT...what ever that is.  Not in the manual.

  • jenart Jun 27, 2008

    I have the same problem on the Canon MX310.  I followed instructions (pg 54-55) in the manual to eliminate the documents stored in memory, but to no avail.  I did get it to print our the "Activity Report" listing what was in the memory.  But when I tried to call each file up to print and delete it, the message I got was memory empty.  What to do next.

    I figured out how to manually print it from memory, but it's a real pain after a while. Is there a way for it to print the faxes automatically instead of having to go to:

    Menu>Memory Reference>Print Memory List>Ok


    Menu>Memory Reference>Print Document> *enter TX/RX* > Ok


  • triplebee May 05, 2009

    I have the MX310 and the message of recommend new c-crt, however, I know the color ink is not low... it is basicall brand new. Any way to shake it up and fix this like with toner cartridges on big printers? Thanks for your help.

=) SOLUTION!!! To print from memory, simply press the "FAX button on the front panel.
Then, press the "MENU" button. "1. Fax Settings" will appear in the display. Press the
"right" arrow key once so that you get "Memory Reference" to appear on the screen.
Press the "OK" button once. It will display "Print List", but you want to "Print Document",
so press the "right" arrow key until you get to "Print Document" and press "OK."
Once you are there, press "OK" again and the message "Print 1st page only?" It displays a YES and NO, so hit the left or right arrow key to choose. If you want to print the entire document,
choose NO and press "OK" Your document will print out!!! =)

I had the same problem with faxes storing to memory. The easiest thing to do is to press:

1. Menu
2. Memory refference
3. Print or Dump memory list.
4. Get the tx/rx (send and receive) number off of that sheet.
5. Go back to the menu and print a document from the menu.
6. It should ask what number document in the memory to print.
7. Put in the tx/rx number from the memory list sheet, and hit ok.
8. I printed everything that was in memory and was still getting the error so after they were done printing I just went back and deleted them from the memory.

Also, your ink cartdriges are labeled "B" and "C" inside the printer when you open the cover. "Recommend new B-CRT" means that you need to change the "B" cartridge. And if you get the "C" message, replace that one as well. The "CRT" stands for cartridge....incase you didn't already guess that. I fought with it for about a half hour trying to figure out what that meant. That should solve your problem.

Hi! I called Canon about this problem. Here it goes....

C-CRT means to replace color ink cart. because it is low on ink or is out.

B-CRT means the same thing, but regards to the black ink cart.

Person I spoke to said he was not sure why they did not list this message in the manual.
Have a great day!

No clue i got the same problem.will contact canon tomorrow

Posted on May 16, 2008

(for the PIXMA MX300)


Pressed menu button, then go to fax settings, then go to memory reference. Then go to memory list, and hit OK...this will give you a list of everything stored in memory. Then to print each document in the memory, go to print document in the memory reference submenu. Then enter the TX/RX No listed on the memory list.

Posted on Apr 10, 2008

On the Canon website, it says this means it wants a new ink cartridge.

B-CRT is the B cartridge, and C-CRT is the C Cartridge. B is the black one, and C is the color one. What's strange is, mine says it wants to change the color one, and we never print in color.

On my Canon MX310, the display says "Waiting for Report". Fax Memory is clear, but the In Use/Memory light stays on.

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

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.

Hi, I got a message: received in memory - recommend new b-crt

The b-crt is the black ink cartridge, when you put in a new one, it will print the fax for you.

Looks like I have an incoming fax: screen reads, "received in mem

You have the fax setting to use memory or no paper loaded.
Go to the fax menu and change it to print.

Receiving Faxes

There is no setting to store faxes to memory by default. If the received faxes are being stored in memory, it's because the machine detects a problem that prevents it from printing them, such as no paper, or no ink. Go to this link and type "print received faxes" in the search box and click Search. You will see a number of items to review for troubleshooting your problem.
