4. Replace Transfer Roller/Transfer Corona
Assembly As Required
Toner "transfers" to the paper because this assembly
puts a positive charge on it. Over time, it attracts toner to
itself and cannot be properly cleaned in the field. Generally
changing it results in immediate print quality improvement.
5. Replace Separation Pad
This part prevents more than one sheet of paper from entering
the printer at a time. As it begins to wear out, multiple sheets
may feed into the printer causing jams. A new pad prevents this.
6. Clean Pick-up Roller Surfaces
The pick-up rollers actually liberate small amounts of fiber
from every page they pick up. Some of this bonds to the roller,
making it slick or dusty. For most machines, cleaning this is a
sure-fire cure for pick-up problems.
7. Clean Beam-To-Drum Mirror
Ozone doesn't attack glass, but it does help toner and paper
dust to bond to the surface of the beam-to-drum mirror. This can
become so cloudy that print quality is seriously impaired.
8. Clean Registration Rollers
Like the pick-up rollers, these become coated with a hard, shiny
white film of paper debris that makes them slick. Solvent
cleaning restores them to original texture.
9. Clean Exit Rollers
This is dome is somewhat the same manner as step 8 above. We
also check the exit belts to be sure that paper does not jam
accordion fashion at the exit rollers.
10. Clean Ozone Fan Bushing Assembly and Fan
Axle
Toner conspires with ozone to "gum up" this fan. If
the fan fails, ozone intensifies its attack on the machine. A
little cleaning here will keep the fan going for years.
11. Tighten or Replace Screws. Check Exposed
Grounds
Loose screws can fall out of the clamshell into the cartridge
and affect output. Loose grounds can cause bizarre and
unpredictable failures.
