Canon 640, 645, 660 & other cartridges - How to reset 'Ink out'

Canon ink printer refusing to print with 'the following ink has run out' error..?

This page explains why you're seing this support code. what it means and how to deal with it. The same process works with most Canon ink printers even though the messages and/or the cartridge numbers in pics may be different.

The following ink has run out error

Canon ink printers are programmed to stop printing, before the ink runs out. Handy feature - unless you plan to refill your ink cartridges, or want to use up any ink remaining inside before replacing them.

If you do (refill), your printer has no way of checking that you've added ink and will continue treating the refilled cartridge(s) as empty and refuse to print with The following ink has run out message.

Note: The following info applies to Canon inkjet printers with twin cartridges (1 x black & 1 x tri-colour). If your printer uses individual ink tanks, you can find the correct info here.

How to clear 'The following ink has run out' Support code ?

  • Install new ink cartridge OR

  • Disable the printer ink monitoring

There are NO chip resetters or auto-reset ink cartridges available for any twin cartridge Canon printer, so these are your only choices.

To disable Canon ink monitoring...

Simply follow the ink monitor messages from your printer, similar to the pics below. If you use a multi function (eg MB, MP, MG, MX, TR, TS etc) printer, similar messages should also display on the printer LCD.

1) When your Canon printer decides a colour ink cartridge is close to empty, you should see this (or similar) message:

  Following ink has run out Canon 510

Do nothing....it should clear itself.

1A) Or...if black cartridge is close to empty, the message would look more like this:

Do nothing...

2) Then you should see this message:

Canon MP240 disable black monitoring

Press and hold the STOP button until the error clears.

Do not cancel printing.

No STOP button on printer? Try RESET or CANCEL. Hold the button until the Alarm LED stops glowing and/or the error message clears. This should take 5-6 secs.

Note: If your printer uses one LED indicator for the black and one for the colour cartridge, they may stay on permanently even with the ink monitor disabled. This shouldn't prevent printing as long as the thirs (alarm) LED is out.

No buttons on printer?

Some late model Canon printers don't have any buttons on the control panel (except on/off) and everything is set on the touch screen LCD. The disabling process is similar to above, except instead of holding a STOP button for few seconds, you will be prompted to touch the OK button (on printer LCD).

There may also be one extra step in the process asking you to confirm your refilled cartridges are not counterfeit. Click NO to the question.

3) Then this message should pop up. Note the exclamation mark and black ink level are no longer showing. Congratulations! You've successfully disabled the black ink monitoring.

MP240 black ink disabled

The printer should now resume normal operation. If it doesn't, check your task tray (bottom of monitor) for any new printer related messages that require attention...like this one.

Ink cartridge has been replaced dialog 

Click OK...

Important notes:

  • Your printer will not stop printing before ink runs out. Top cartridges up regularly.
  • It is not possible to disable the Canon ink monitor in advance (for a cartridge not registering as empty).
  • Repeat the above process when another cartridge registers empty.
  • Fitting a brand new cartridge in printer will enable the ink monitoring. Both cartridges would have to be replaced - to enable monitoring for both.
