Problem: The printout from the LaserWriter II is black except for the top
which may consist of 5 thin white lines 1 to 1.5 inches apart. There is also
excess toner spilled around the corona wire assembly. This may occur after the
corona assembly or the transfer guide assembly has been removed and replaced.
Cure: There is a brass colored grounding tab on one side of the transfer guide
assembly, (if you are facing the printer from the paper tray end it's on the
left side of the corona assembly) that should be in contact with the grounding
spring on that side of the corona assembly. The tab pivots and can be in the
wrong position when the corona assembly or transfer guide is removed and
reinstalled.
