I'd guess it could be the erase lamps for the photoconductor drum. If they're
not working properly (or firing then going out) then you might end up with
this fault. I'd defeat the interlocks and cartridge sensors, then cover the
laser aperture and see if the erase lamp comes on before the paper starts
feeding. IIRC the procedure is in the service manual.

Failing that, it could be a dirty transfer wire, or maybe a dirty (or worn)
drum cleaning wiper.
