Businesses providing maintenance of office machinery inspect, service and repair equipment used in workplaces. This can include printers, photocopiers and multifunction devices, scanners, fax machines, shredders, laminators, binding machines and franking or postage equipment. Work may involve diagnosing faults, replacing worn or damaged parts, clearing paper jams, updating device software and checking that machinery operates safely and reliably. Services are often arranged as one-off repairs or scheduled maintenance visits, either at a customer's premises or at a workshop, depending on the equipment and fault. Technicians may clean and calibrate machines, test print or scan quality, and advise on correct operation to help reduce breakdowns. Some providers also supply or fit consumables and parts, such as toner, ink, rollers and feed components.
