Hmmm... it could be a bad contact in any location, but look at the
cartridge for the metal contacts and clean them both on the cartridge
and the printer itself. Someone suggested to me it was probably a dirty
Corona wire, but that is less likely based upon your scenario. However,
it could be the Corona wire is not being charged correctly because of
the contact source to the printer. Most printer toner cartridges have
one or more pads, or surfaces which have metal contact points. Make
sure they are all fully clean of corrosion or residues, for either side
of the connection.
