This process is similar to using glue to write on a can and then rolling it over glitter. The glitter sticks to the glue
but will not stick to the rest of the can.
Service tips
• Never touch the surface of the developer roller with your bare hand. The oil from your skin may cause a
charge dierential on the surface, and the toner will not stick properly. The result would be repeating
blotches of voids/light print on a page, and the aected cartridge will have to be replaced.
• If the developer roller is damaged, it will not contact the surface of the photoconductor properly. The result
could be repeating marks, thin vertical voids, or thin vertical lines of color on the printed page. Check the
surface of the developer for damage.
Step 4a: First transfer
When the latent images are developed on each photoconductor, the HVPS sends voltage to the
first
transfer
rollers inside the transfer module.
