When you say sometimes print or copy doesn't come....I assume you mean blank or light copies. Which one is it, blank or light. Starting with the coronas was a good 1st step. Is the drum shaft screw tight? Intermittant problem with the laser shutter? Have you tried adding toner in service mode? Need more info to properly help you.
