10 days ago I answered the question from Canon's support person...I still have no reply to my reply. That is hardly "immediate". Still waiting for answers.

Oh, and when I did try to call for support, I am told the issue "cannot exist". That the cartridges "have to work" if they are legit Canon. They are 100% legit and the issue most certainly DOES exist.


I can understand how the issue can be frustrating. There could be a couple of factors that can be a part of the issue. If the toner shows that it is low after 4-5 days, it could be caused by the level in the toner cartridge or a problem with the hardware. You can check the printer's toner level using the steps in the link HERE to see where the level is for a specific color. You can also change the settings for the toner replacement message. You can change it to lower toner level percentage if the percentage is too high.

<Menu>  <Preferences>  <DisplaySettings>  <Display Timing for Cart. Prep.>  Select <Off> in <Auto>   Enter toner level in <Custom> 

To assist further we would need some more information about the toner and the specific messages you get. What model toner cartridges are you using? Also, since it has been over 4-5 days since the last post, have you run into the problem with the toner? If so, what specific messages did it show for the toner or the toner level? When you check the toner level now, what does it show for the amount?


She just replaced the carts recently and it says Yellow is "at the end of its lifetime", it is most definitely not. I changed settings as per the above. Carts are Canon branded.
