Hi, I'm Sadique. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
Do you see any error code?
for eg: B200
I am afraid to say, Error code C000 is a line feed error. It indicates an error in LF encoder signal. It is caused due to smearing or scratches on the LF / EJ slit film.
How old is your printer?
LF / EJ slit film and the LF / EJ timing sensor unit needs to be replaced to get everything back to alright.

Sorry to give you a bad news.
I wish I had a better answer for you.
