HP LaserJet Pro CM1415fnw thick black horizontal lines on first few prints

Printer: HP LaserJet Pro CM1415fnw Color Multifunction Printer

Recently I started having this issue where the printer will print random thick black horizontal lines across the paper. The weird thing is that it will only do this with the first few prints; after that, it will work fine.

Has anyone heard of this issue before, and if so, is there a fix?

I have already tried to clean the printer through the settings.

Thanks for your help!
