Pixma mp460 UO51 error in my printer ---- i refilled the empty printer carts and it wont read the carts level it says the black and colour are not recognized. any way it can be reset so that it will print ?

CL41, this is the one you are using for your cartridge.

Did you change your cartridge with brand new one or refilled one??

If you did with refilled one, the ink level won't go back with full.

-------------------------------------------------------------------------------
This is the method how printer measures the ink level.

1. Each cartridge has a serial number.
2. As soon as installation in printer, printer recognizes the cartridge by serial #.
3. And the printer starts to count the printing document.
4. After reaching certain print counting, the ink level will show "low ink"

So my answer is even if you refilled your cartridge, the ink level won't change,
since printer cannot weight the cartridge or.....some other technology to measure each color ink level.

Thanks.

cartridge may got dried. put them in hot water for 30 minutes and try again.

You need to check that the canon label on top of the cartridge is near to the to the two lugs, there should be only a tiny gap. The label should not be placed at the bottom near the curved lug. If it is not in the right place I think it covers the chip that talks with the printer and thus sends an error message.

You can refill them but you have to do it striaght away otherwise it dries up and is knackered. Do it yourself remove the label on top and drill 3 holes for the colour (you can get a guide for it with refill kits) sending them somewhere will cause them to dry up, as they need doing as soon as you loose a colour.
For now get a new cart and fill that when it runs out.

hi guys,
BTW, did you refill the cartridge?. First, try to press START button (Black or Colour). Perform this procedure for each cartridge. If the problem still persist there some possibilities: cartridge error, carriage part or logic board is faulty. Then you need to replace faulty part.

Dear lim,
Here a solution for you. The cartridge of this printer has memory chip that store ink level data inside. Once the cartridge is empty we cannot restore ink level data to be full. To continue using refilled cartridge you need to deactivate ink level detection function first. Perform this step: when the message 'The following cartridge cannot be recognized' appears press Resume/Cancel button. Do this for each cartridge you refill;if you refill both black & colour cartridge do this tip two times (once for each cartridge).
Please rate this as fixya ok.
Regards,

Check the Label on the cartridge if it covers a certain area then you will get an error message. Compare it with a good cartridge the label should nearly touch the lugs at top end. Only applies to refilled Carts.

I think you printer cartridge as sensor which ink levels as it is failed in the black cartridge ,you can either clean the contacts the printer and cart with dry tissue paper and replace and set printer installing new cart or use it like this because the printer company doe not support refilled cartridges to be used .

Are you using official Cannon cartridges or "ink refill" cartridges? Did you reset your ink levels in the software?
