Question HP Printer making dark lines on pages

[printer_guy101]

My printer (HP Color LaserJet Pro M452dw) is making dark lines on the right side of any printed page. It happens with every color, so I don't think its the toners, and I've cleaned the transfer belt. I've also done the clean page diagnostic, which fixes the problem for a while, but the lines still come back. Here's what it looks like: Image Link

Looks like you have ink on the roller.
You might have to dig in to the machine a bit and see if it has a collection troff/sponge that is full. Clean any of the ink supply areas with rubbing alcohol..could be a cloggy bit that's misaligning it's aim

Maybe you have a dirty scanner or roller. Make sure you have appropriately installed a genuine ink cartridge in your printer. Clean the scanner glass or roller with a lint-free cloth. Also, clean the printer printhead properly.
