Laser printer lines across page 🤔

Can anyone suggest what causes these lines across the page?

Is a new toner cartridge likely to fix this?

Edit: Line separation is 62.5mm

Edit 2: Thank you to everyone who replied. I've ordered a new toner cartridge and will update this if that solves the problem 🫡

Final update: A new toner cartridge fixed it. It's now printing perfectly! Thank you.
