Computer, ATM, and Office Machine Repairers

Computer, ATM, and office machine repairers install, fix, and maintain many of the machines that businesses, households, and other consumers use. Show Details

Duties

Computer, ATM, and office machine repairers typically do the following:

  • Travel to customers' locations in response to service requests
  • Communicate with customers to determine the source of a problem
  • Do administrative tasks, such as completing work order forms
  • Use a variety of tools, such as a multimeter, to help diagnose the problem
  • Install large equipment, such as mainframe computers and ATMs
  • Explain the basic functions of machines and equipment to customers
  • Replace malfunctioning machine parts, such as video cards in desktop computers or keypads on ATM machines
  • Provide preventative maintenance, such as cleaning the internal parts of machines
  • Test newly installed systems to make sure they work properly

In most cases, machines do not break down entirely. Often just one broken part can keep a machine from working properly. Repairers often fix machines by replacing these parts and other defective equipment because it is often less expensive than replacing the entire machine.

Although the work of computer, ATM, and office machine repairers is very similar, the exact tasks differ depending on the type of equipment. For example, computer repairers often must replace desktop parts, such as a motherboard, because of hardware failure. ATM repairers may replace a worn magnetic head on a card reader to allow an ATM to recognize customers’ bank cards. Office machine repairers replace parts of office machines that break down from general wear and tear, such as the printheads of inkjet printers.

Some repairers have assigned areas where they do preventive maintenance on a regular basis.

Computer repairers service and repair computer parts, network connections, and computer equipment, such as an external hard drive or computer monitor. Computer repairers must be familiar with various operating systems and commonly used software packages. Some work from repair shops, while others travel to customers' locations.

ATM repairers install and repair automated teller machines and, increasingly, electronic kiosks. They often work with a network of ATMs and travel to ATM locations when they are alerted to a malfunction.

Office machine repairers fix machinery at customers’ workplaces because these machines are often large and stationary, such as office printers or copiers. Office machines often need preventive maintenance, such as cleaning, or replacement of commonly used parts as they break down from general wear and tear.

Electrical and Electronics Installers and Repairers

Electrical and electronics installers and repairers install, repair, or replace a variety of electrical equipment in telecommunications, transportation, utilities, and other industries. Show Details

Duties

Electrical and electronics installers and repairers typically do the following:

  • Prepare cost estimates for clients
  • Refer to service guides, schematics, and manufacturer specifications
  • Repair or replace defective parts, such as motors, fuses, or gaskets
  • Reassemble and test equipment after repairs
  • Maintain records of parts used, labor time, and final charges

Electrical and electronics installers and repairers work on complex pieces of electronic equipment.

Automated electronic control systems are becoming increasingly complex. As a result, repairers use software programs and testing equipment to diagnose malfunctions. Among their diagnostic tools are multimeters—which measure voltage, current, and resistance—and advanced multimeters, which measure the capacitance, inductance, and current gain of transistors.

Repairers also use signal generators, which provide test signals, and oscilloscopes, which display signals graphically. In addition, repairers use handtools such as pliers, screwdrivers, soldering irons, and wrenches to replace faulty parts and adjust equipment.

Commercial and industrial equipment electrical and electronics repairers repair, test, adjust, or install electronic equipment, such as industrial controls, transmitters, and antennas.

Electrical and electronics installers and repairers of transportation equipment install, adjust, or maintain mobile communication equipment, including sound, sonar, security, navigation, and surveillance systems on trains, watercraft, or other vehicles.

Powerhouse, substation, and relay electrical and electronics repairers inspect, test, maintain, or repair electrical equipment used in generating stations, substations, and inservice relays. These workers may be known as powerhouse electricians, relay technicians, or power transformer repairers.

Electric motor, power tool, and related repairerssuch as armature winders, generator mechanics, and electric golf cart repairers—specialize in installing, maintaining, and repairing electric motors, wiring, or switches.

Electronic equipment installers and repairers of motor vehicles install, diagnose, and repair sound, security, and navigation equipment in motor vehicles. Motor vehicle installers and repairers work with an increasingly complex range of electronic equipment, including DVD players, navigation systems, and passive and active security systems.

Electrical and electronic installers and repairers may specialize, according to how and where they work:

Field technicians often travel to factories or other locations to repair equipment. When equipment breaks down, field technicians go to a customer's site to repair the equipment. Because repairing components is a complex activity, workers on the factory floor usually remove and replace defective units, such as circuit boards, instead of fixing them. Defective units are discarded or returned to the manufacturer or a specialized shop for repair.

Bench technicians work in repair shops in factories and service centers, fixing components that cannot be repaired on the factory floor. These workers also locate and repair circuit defects, such as poorly soldered joints, blown fuses, or malfunctioning transistors.
