You most likely are using aftermarket or refilled cartridges. These will normally not register as full. Here is a link to a procedure that should solve issue. Watch the video and follow the instructions....


Canon 240 241 Cartridge Ink Level Reset Procedure Pixma MG MX Printers

Apparently the problem is that you are choosing to install (according to Canon), cheap, aftermarket ink cartridges rather than Canon ones. Therefore the machine is not recognizing them. Try this procedure, found on another forum, that was supplied by one of the cheapo ink companies. Who better to know how to fool the machines than them. If they want to sell these ink carts, they better know who to make them work!

1- Switch off the Canon MX300 and disconnect the power cable.

You must have power applied to the unit when you change ink cartridges. The cartridge holder should move to the left side of the carriage when you lift the cover to gain access to the ink cartridges.

I'm assuming when you said "fine catridge" you meant FINE cartridge. FINE is an acronym for the Canon Ink Cartridges. Anyhow, plug your printer into the electrical outlet and turn the power on. Wait about 1-3 minutes and open it up and the Ink Cartridge holders should move to the left for you to properly insert your Ink Cartridges.

if you purchased a canon 310 mx and if it is new..contact the supplier about it.So that they can instruct you how to fix it..Good day

Make sure the printer is powered on, then open the cover. If the cartridges don't move to the center within 30 seconds or so, the printer may need service.

You may need a new cartridge, that error says the ink cartridge is wrong or not installed properly. If it's a refilled cartridge it won't work, if it's a new canon cartridge, they warranty for 30 days from date of purchase.

All catridges are made to show the ink levels only for 1st use, once you refill the cartridge you need to reset the ink level chip, some cartrides level cannot be reset, some can be re-set.
There are solution available for some specific printer ink cartridges on how to re-set the ink level.
You can google and loacte the solution giving cartridge number in the search field of google.
