Horizonal lines printing on the page

[JimBerg]

Horizonal lines are printing on the page, not every page but approximately 3 out of 5 pages. I have replaced the toner cartridge, performed the Service / Cleaning Page multiple times (6), and cleaned the foam roller but horizonal lines are still printing on page. Any suggestions?

I attempted to follow the instructions to update the firmware. However after step 3, I found no options that led me to Printer Update or Product Update. I did look on the printer and found the firmware datacode = 20150212. 

If you have any other suggestions on how to update the firmware and/or fix the problem with the horizontal lines, please let me know.

I did a google search and found this page. 

https://support.hp.com/us-en/drivers/selfservice/hp-laserjet-pro-200-color-printer-m251-series/50976...

On it, it lists my printer and the latest version of the firmware of 20150212, which matches what is installed. 

Do you have any recommendations to fix the horizontal line problem since the firmware is up to date?
