    Same problem here, keep printing that stupid "Error TX REPORT".

    On the Fax menu, it is shown that memory in 10% full, however, when I list the document in the memory, I get the message that there is no Document in the memory...

    That is stupid...

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.

    Thank you! Someone tried to fax and my machine is not set up to fax, and I've been struggling to fix this for hours! I think this did it.

Here's our / your situation nightmare - the screen says 40 or say in my case 100% memory full and there is NO way you can fax right?  or scan another fax adf into memory to send.  You are pulling your hair out????  that was me - actually I was just about to SMASH THIS MACHINE and NO THANKS to Cannon for zero help on their website - except pushing more of their products every time I typed mp830 how to clear memory - that should be #1 on there FAQ!!!
Answer you HAVE to print ALL reports - I usually don't want to because it wastes paper and I always hit the stop -  why do I need to print the report - I have two eyes - I can SEE the fax didn't go thru - Duuuuuuuuuuuuh  - this happens when say a fax doesn't go through or wrong #.  Now in the past on ALL faxes you can / could turn this option function off.  THANKS CANNON for making it not possible - ooooooooh  Yeah you waste a ton of ink on all of these stupid not needed reports - why you might ask? 
let's say your fax like my situation has 100% memory full - that means I have 10 reports in memory (which I had zero idea about) -  each report amounts to 10% of that memory - that thanks to Cannon they MUST be printed before I can use it again! 
That's lame & NOT GREEN  SHAME on you Cannon - meaning I have to wasted ALL that ink and paper on something I don't want to waste or print!  but NOPE you don't have that option - that's crazy!!!   I looked far and wide to find another solution - and no as the many cooky solutions I saw on this site or others DON'T WORK - turning your fax on and off and unplugging it doesn't work... NEXT
isn't that wonderful!!!  I can only imagine my fellow readers of this who been FREAKING out for days on end (like me!!!)  how to fix this - and zero help.   Nightmare city
On my previous fax machines I owned  you had the option to turn printing reports off.  Nope not on this Cannon - to my knowledge and research - so let's waste more paper and spend tons more on the already WAY over priced ink!  Shame shame

Try this first: Reset the device when it does not respond. If the device does not respond, disconnect and then reconnect the power cord. At the device or at the electrical outlet, disconnect the power cord or adapter. Wait approximately ten seconds and then reconnect the power cord. Wait until the device has completed its cycling process before submitting another job request.

You can print and delete faxes from memory: 1.- Make sure the FAX button is lit (press it if not) 2.- Press Menu 3.- Press the Right Arrow button once to select Memory Reference then press OK 4.- The menu should now show - Print Memory List - Print Specified Document - Select Specified Document I am sure you can take it from there.

I can't erase the faxes I already send

Hi There,

While not as popular as they were before the Internet became a principal means of business communication, fax machines are still an essential item in many offices. They are particularly useful on business documents when a signature is needed. Canon makes a number of fax machines that use both ink-jet and laser technology to receive and print documents. Most fax machines store incoming faxes in memory so you can reprint them, but occasionally the memory becomes full resulting in an error message. Your Canon fax machine's memory can be cleared quickly and easily so you can start using it again.


* Click the "Menu" button.

* Press the arrow buttons to scroll through the options on the screen. Select
"MEMORY REFERENCE" and click "Start/Copy."

* Use the arrow buttons to choose "DEL. PRINTED RX" then click "Start" again.

Press "*" to select the "Yes" option from the screen. This will delete all documents from the fax machine's memory.

* Click "Stop" to finish.

Read fax in memory MP830

it won't print faxes if ink is too low so it stores them until you replace the low cartridge or cartridges. Don't know if you can transfer to computer. Do it the other way around and go to I did and I love it.

I dont remember how to recieve a fax!

I find that you have to have the fax button lit up. If it is not lit up when a fax comes in, the fax is stored in the memory. You have to hit the fax button, go into the menu and go to memory reference, then the doc # of the item in memory should appear. You should then be able to print the stored fax. Hope this helps!

I had the same problem - it would not print the faxes as the machine would not recognize the generic cartridge - I had to get the official Canon cartridge to get the faxes to print out of memory.

Faxes being sent but stuck in memory, How do I Print them out?

Printing Documents in Memory: From B640 Manual

Except when you run out of paper, the faxphone will automatically print out the contents in memory when you remedy the cause of the problem.

If running out of memory caused memory reception, adding recording paper and press {STOP} to begin printing the stored page(s).

After printing the page(s) in memory the faxphone erases the documents from memory.
