Along with the vertical streak of light type that runs the entire length of
the page near the left margin, that same streak has a rough texture to it
when your run your finger over it. The rest of the paper feels normal. Any
ideas what could be causing this? Would cleaning the laser scanner unit be
the next logical step as explained

Thanks for your reply.


The roughness is probably iron filings, the so-called developer.
Maybe dampness, maybe contamination, its not flowing correctly, plus
loss of the material leading to gaps and consequent non moving of the
toner in one section.
Try removing the cartridge and shaking about , to redistribute the filings
