My MX492 suddenly started printing thick solid black lines on every line. I have two columns of solid black. It printed fine yesterday. How can I find the problem and fix it?

Hi MDoty,
I recommend performing a nozzle check first. This will help narrow down any hardware issues. Please click HERE for the steps to print the nozzle check.
Once the nozzle check prints, please compare it to the picture below and please let us know if they match.

We look forward to your reply.
