yesterday morning it was working fine, but in the evening it started leaving an unprinted vertical stripe, about a quarter of an inch wide, on every page, always in the same place.
I ran a cleaning cycle, and shook the drum and cartridge (I changed the cartridge not long ago, but it is old stock past its date) but no improvement. There was a modest amount of grey fluffy dust that I wiped away with a tissue.
Very strangely, the "Test Print" page looks fine, but emails, PDFs and reports from other packages don't.
Any ideas what I should be looking for, or at?
