Any ideas what's causing it? I'm guessing it must be a fairly cut-and-dried issue, but Google isn't helping. Everything looks clean inside the printer and I've given the cart a good shake (which concludes my knowledge about printer servicing)
This is an otherwise blank printed page of A4 (text etc prints fine).
It's an ancient B&W HP LaserJet 5:

It's too perfect for the issue to be caused by some kind of ink leak.
Definitely an electrical problem.
These kinds of printers work by putting an electric charge on specified locations of the drum, which then attracts ink particles which are pressed on to the paper as it rolls past.
For this reason, I'd suggest there's a constant charge being passed to the end of the drum.
It's a laser printer so the charge is provided by a laser hitting the drum where a charge is desired. The laser must be uniformly hitting the drum, constantly, at the end. Or there's some other thing causing a constant charge at that end.
That's as much a I know. Useless really.
TL;DR: Problem is electrical. Probably can't be fixed with a bodge.
EDIT: Found this image:

Something in that assembly - some part where the laser or the electric charge provision is involved - is broken or needs cleaning. |

Laserjet 5?
Its pushing 20+ years old, bin it and but a refurb LJ4200 for £45 delivered.
Most parts, fuser, transfer roller, laser assy, will cost more. ____________________ TZR250 2MA road, TZR250 1KT road, TZR250 2MA race, TDR250, YZF-750R Boost colours.
