My pixma mp190 will not print. It will start the first line then stop. I have uninstalled it and then reinstalled it but nothing is working

Scanning isn't related to the cartridges problem unless you meant copying. The instructions to align the cartridges might help, if it insists on alignment after new cartridges are added.

Did you remove the (usually pink) tabs from the cartridges before installing?
Did you get a printout from a test page or from the cleaning operation?
Also try a removal, then reinstall of the device.

Driver issue. Uninstall and reinstall driver for win 8 64 bit - should work if same worked before. Did you try a system restore to time when printer was working properly?

It sounds like a driver problem. Unplug the printer from the power and computer. Uninstall the drivers completely and then use the original disc that came with the printer to reinstall everything. Leave on automatic updating.

This is a problem that frustrates many people. I found that there are two ways to defeat this and they are both shown hre.

On some (just a few epsons and dell) there are ways to get around it but printer manufacturers are getting better at stopping this.

Anyway I hope the help from that link will let you dind somthing that gets round the problem for good

In printer utility settings, you have to modify the ink cartridge settings and specify that printer should use only black ink cartridge. Click apply. Then press "stop\reset" button for 5-7 sec. and then release
it. Then it will work!

I suggest you uninstall the full system scaner, printer & coppier unplug it totally. then restart it run cd, then plug the device again after finish installetion restart it and try it. i wish you find good result.

you can reset low ink error by pressing stop/reset button for 10 seconds

this sounds like a virus any ways, make sure u have a very good antivirus, remove and reinstall the printer with the driver but first go to the printer delete all the printers installed manually i.e after uninstalling the printer and its still showing the printer at printer and faxes, then reinstall it.

I have a canon printer MP190. How do I do the reset after completing my ink cartridge to the syringe?

Uninstall and reinstall the printer driver
