C. Thermal printers use a heating element. It heats up spots on special waxy, heat- sensitive paper to form the image.
A. When a laser printer requests maintenance, it’s because it has reached a certain page count. Apply a proper maintenance kit (one recommended by the manufacturer) and then clear the service message.
B. PCI-X slots are physically compatible with PCI adapters. Because all PCI-X slots support the 66MHz minimum clock rate, PCI-X slots are compatible with 66MHz PCI adapters.
C. There are dozens of peripherals on the computer market. Joysticks are used primarily to play video games. Barcode readers will scan item barcodes, such as items you purchase at a store. Motion sensors are usually associated with security systems. Smart TVs play television. Camcorders are another type of peripheral, used to record video.
