I spoke to a copier-expert, and showed him similar output from my 
NeXT Laser Printer (the light band on the right side). He took one
look at it and said that the culprit is a dirty corona wire. Since
the corona wire on a Canon SX laser printer is in the EPS toner
cartridge, it can vary from cartridge to cartridge. I believe that
the recycled cartridges could fall into this category, although
in my case the toner was brand new.

You can manually clean the corona wire. I believe the instructions for
doing so are in the NeXT Users Manual.
