Hp says you have a bad scanner unit(laser unit) or DC controller, but first reseat all your connectors on your scanner unit(laser) and DC controller. Your scanner is located under the top cover and the DC controller is located behind the right cover. If the problem still persist replace the scanner first.

Restart the computer in safe mode and try and delete the printer. If that doesn't work download the the Kyocera print driver seleter from kyoceramita.com and use it to delete the driver.

First you need to clean the machine. Next you need to try a nother toner cartridge. If it still does it you mite need a fuser.
Also does the paper reach the fuser?

This is a common problem for the 4350 ( the first series),

they have since then modified them.

the problem come from the Fuser section, there is a gear which starts to wear out and slips,  there is an update for it.
