Step 1 Remove toner, paper fluff and dust from the
fuser assembly. Check & replace as necessary.
The fuser assembly can generate high repair bills. We remove
contaminants before they cause serious damage. The operating
temperature is very high
and repair in time can save a lot of damage.
Step 2 Check & clean assemblies and paper trays.
The highly complex mechanical units used to move paper and
separate sheets need periodic cleaning in order to function
properly.
Step 3 Replace and clean filters.
Ozone filters need to be replaced once a year and other
filters need to be cleaned for proper circulation of air.
Step 4 Replace/clean image transfer assembly.
Older machines use Transfer corona whereas newer machine use
transfer rollers, both need to be cleaned periodically.
Step 5 Inspect and clean paper pick up roller.
The printer use friction for paper pickup. The roller can
get slick on usage. This needs to be restored or replaced
periodically.
Step 6 Lubricate machine with appropriate high
temperature grease.
Although lubricated at the factory, the lubrication dries
out due to heat, dirt and motion making re-lubrication
necessary.
Step 7 Clean exit rollers.
Like the pickup rollers the exit rollers also get coated
with hard shiny film and debris. Solvent cleaning restores
them to their original texture.
Ir-restorable rollers need to be replaced.
Step 8 Thoroughly clean the electronic bay using
vacuum or compressed air.
The dirt and dust can become conductive under humid
conditions and damage the circuit boards. The dust etc. is
to be removed from electronic
assemblies using air or vacuum.
Step 9 Tighten and replace screws and grounding
straps.
Screws that have worked lose inside a printer can fall into
the cartridge or into the machine gear trains and cause
severe damage.
Step 10 Inspect Replace and clean separation belts
and rollers. All printers use a cork separation pad or
rubber rolls to feed one sheet of paper at a time into the
machine.
Step 11 Clean and lubricate fan assembly.
Toner, paper dust, dirt conspire to gum-up the exhaust fans.
Cleaning will help to keep the fan going for years.
Step 12 Inspect and clean registration assembly.
This unit is removed and cleaned with a rubber roller
restorer to ensure proper registration and fewer paper jams.
Step 13 Inspect and clean beam-to-drum optical path.
The printers use a mirror and lens combination in the laser
optical path to focus and direct the laser beam to the
Optical Photoconductive drum of
the toner cartridge. The dust can settle on the surface of
these optical devices and impair the print quality.
Step 14 Test the machine for smooth operation and
sharp and crisp printouts.
Our vested interest;- The poor health of your laser printer
is injurious to our business.
