- Remove toner, paper dust from fusing assembly, check the assembly, and replace as necessary
the fusing assembly can generate high repair bills. We remove contaminants before they do serious damage! Damaged units should be replaced at the time of cleaning, saving the cost of a future service call.
- Check and clean job off-set, switchback, duplex assemblies, and auxiliary paper trays
These highly complex mechanical units, used to move paper and separate jobs, needs periodic cleaning in order to operate properly.
- Replace and clean machine filters
older laser printers produce ozone and have ozone filters that must be changed annually. Newer machines do not produce large quantities of ozone, but they require their static filters to be cleaned for proper air circulation.
- Clean image transfer assembly
older machines use a high-voltage transfer corona mechanism and generate large amounts of ozone. These machines require periodic replacement of the transfer corona assembly, because the toner attracted to it must be ultrasonically removed and cannot be properly cleaned in the field. Newer machines require periodic cleaning of the transfer roller assembly.
- Inspect and clean pickup roller surface
Pick-up rollers can become slick and ineffective over time. Using a rubber roller restorer, these rollers are returned to new condition. Un-restorable rollers and pads should be replaced at time of cleaning as needed.
- Lubricate machine with appropriate high-temperature grease
Although drive gears in printers are properly lubricated at the factory, over time the heater of the fuser and the motion in the machine combine with paper dust, toner and dirt to dry out the lubricant, making re-lubrication necessary.
- Clean exit rollers
Like the pick-up rollers; exit rollers become coated with a hard, shiny white film of paper debris that makes them slick. Solvent cleaning usually restores them to their original texture. Un-restorable exit rollers should be replaced at time of cleaning as needed.
- Thoroughly clean the electronic bay of the machine, using a vacuum and compressed air
Dust and dirt, especially toner, can become conductive on circuit boards, causing premature failures. With the machine's covers removed, our technicians can thoroughly clean the entire electronic assembly of these contaminants.
- Tighten or replace screws and check grounding straps
Screws that have worked loose inside a printer can fall into the cartridge or into the machine gear trains, causing severe damage.
- Inspect, replace and clean separation pads and rollers
Printers use a cork or plastic/rubber separation pad and rubber feed rollers to feed one sheet of paper at a time into the machine. Separation pads, sub pads and feed rollers should be replaced if worn or un-restorable.
- Clean and lubricate fan assembly
Toner, paper dust, dirt and ozone conspire to "gum-up" exhaust fans. A little cleaning will help keep the fan going for years.
- Inspect and clean registration assembly
this unit is removed, inspected and cleaned with a rubber roller restorer.
- Inspect and clean beam-to-drum optical path
some machines have a mirror in the laser optical path to direct the laser beam to the machine's image drum. This mirror can become so cloudy that print quality is seriously impaired.
