I have been given a Panasonic 6100 laser printer and it is putting 3 black
stripes across the page, about one third of the way round the transfer
roller I would reckon. Is there anything I can do, bar buying a new
transfer roller?

With mono laser printers available for as little as £125, it is rarely worth
buying major components for old ones these days.

Epson 1000 fuser cogs died - £300 for a new fuser unit

Epson 1100 new - £250

... I think your case is proven ...
