Ck cartridge won't go off even after I put new cartridge in

ck the conns at the starter

hello,
print head(cartridge carriage unit) is complaint, you have to replace.

Its simply because the cartridge is not making a good contact with its socket.
1-switch off the printer and totally unplug it 2-clean the cartridge properly
3- check the cartridge clip
4-return cartridge and send a feedback to us

Has all protective tape been removed from copper contacts?

I have the same problem. Everything on the printer is working just fine. It'll do a test page just fine, so everything's working right. The %$^ thing just won't print. It makes noise like it's printing when you give it a print job, but it spits out blank pages.

Follow these steps on how to install the cartridge: 1. Make sure the printer is on. 2. Lift the access cover. The print cartridge carrier moves and stops at the loading position, unless the printer is busy. 3. Press down on the left cartridge carrier lever to raise the cartridge carrier lid. 4. Remove the used print cartridge(if you are replacing). Insert the new black cartridge in the left carrier. 5. Snap the lid closed.

Sometimes the ink cartridge carrier won't automatically move to its loading position even when the printer is on and the cover is open. Follow the steps below:

1. Unplug the printer from the power source.

2. With the cover open, hold the solid white strip that connects from the carrier assembly to the ink cartridge carrier and gently slide the cartridge carrier to the center of the printer.

3. Remove the used cartridge.

4. Load the new black cartridge. Close the cover.

5. Plug the printer back to the power source.

Did you used refilled cartridge?

Sometimes for Canon printer, when u used refilled cartridges, they are not readable.
It's called E5 error.

In this case, you need to replace the cartridge with new one.

If you would like to save money, try refill kit by "ROADINK".
Not only they are easy, but also the printing quality is good.
For your better understanding pls check out my youtube video.
And will see how easy ink refill can be done.

lift the lid,. there may also be a cartridge change button,. otherwise with the power on the cartridges should move to the position to change them,. pop them out and put the new ones in...

Once remove both the cartridges from the all-in-one and then clean the copper contacts of the cartridges and then put only black cartridge and check for the message displayed on the all-in-one if it even reads check right cartridge then the issue is with the all-in-one hardware. If it reads insert right or color cartridge then the issue seems to be with the cartridge.

Remove the cartridges from the all-in-one and power cycle the all-in-one and then reset.

Now insert the cartridge and check for the result. If the issue still persists then check the expiry date on the cartridge and once replace the cartridge and check for the result.
