Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Inkjet Printers Fourth Edition • An inkjet printer uses a printhead connected to a carriage that contains the ink. A belt and motor move the carriage back and forth so the ink can cover the whole page. A roller grabs paper from a paper tray (usually under or inside the printer) or feeder (usually on the back of the printer) and advances it through the printer. © 2012 The Mc.

Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Inkjet Printers (continued) Fourth Edition • Inkjet printers – Simple devices that consist of the following: • Printhead, support electronics, a transfer mechanism, and a paper-feed component – Work by ejecting ink through tiny tubes • Ink is heated by tiny resistors or electroconductive plates at the end of each tube. • The resistors or plates boil the ink, which creates a tiny air bubble that ejects a droplet of ink onto the paper. • Some inkjets use mechanical methods to eject ink. • Most color printers are inkjet and produce a high-quality image. © 2012 The Mc.

Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Fourth Edition The Electronic Printing Process (continued) • Raster image – – Impact printers print a line at a time. Laser printers generate a raster image of the page. A raster image is a pattern of dots. The raster image processor (RIP) chip translates the raster image into commands for the laser printer. © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved

Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Fourth Edition The Electronic Printing Process (continued) • RIP needs RAM in order to store this data. – Mem Overflow error indicates insufficient RAM. • Add RAM, reduce the resolution, or print smaller graphics. – HP Laser. Jet 21 error means the data is too complex. • Reduce complexity by using fewer fonts and less formatting, reducing graphics resolution, and so on. • Resolution enhancement technology (RET) – Enables the printer to insert smaller dots among the characters to smooth out jagged curves. – Disabling RET helps reduce MEM OVERFLOW errors. © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved

Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Fourth Edition The Electronic Printing Process (continued) • Resolution – A laser printer can print at different resolutions. – Resolution is expressed in dots per inch (dpi)— for example, 600 × 600 or 1200 × 1200 dpi. • The first number is the horizontal resolution—how fine a focus can be achieved by the laser. • The second number is the vertical resolution—the smallest increment by which the drum can be turned. © 2012 The Mc.

Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Fourth Edition Setting Up Printers (continued) • Installing a local printer: – Since Windows will automatically detect and install USB printers (or any other plug-and-play printer), this option is most commonly used to install printers using a parallel connection or to install standalone network printers using an IP address. – Should not need to use Add Printer Wizard or IP address with a standalone USB printer. © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved

Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Fourth Edition Setting Up Printers (continued) • Installing a local printer (continued): – Windows won’t automatically detect a new parallel device. For a parallel port printer using Windows XP, check the Automatically detect and install my Plug and Play printer option. – When you check this box and click Next, Windows XP will run a search for any plug-and-play printers, including those connected via parallel cables. – Windows Vista and Windows 7 don’t include this option; you’ll need to configure parallel-connected printers manually by selecting a port and driver. © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved

Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Fourth Edition Setting Up Printers (continued) • Installing a local printer (continued): – If you need to install a standalone network printer using its IP address, uncheck the Automatically detect and install my Plug and Play printer option in Windows XP and click Next.

Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Fourth Edition Troubleshooting Thermal Printers • Thermal printers are simple to troubleshoot and maintain. – With direct thermal printers, you need to worry about only three things: the heating element, the rollers, and the paper. – With thermal wax printers, you also need to care for the wax ribbon. • To clean the heating element, turn off thermal printer and open it according to the manufacturer’s instructions. Use denatured alcohol and a lint-free cloth to wipe off the heating element. Use a little pressure to get it completely clean. © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved

Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Fourth Edition Troubleshooting Thermal Printers (continued) • Clean the rollers with a cloth or compressed air. You want to keep them free of debris so they can properly grip the paper. • Replacing the paper is as easy as sliding off the old roll and replacing it with a new one. Remember to feed the paper through the heating element, because otherwise you won’t print anything. © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved

Mike Meyers’ Comp. TIA A+® Guide to Managing and Troubleshooting PCs Fourth Edition Troubleshooting Thermal Printers (continued) • Replacing the ribbon is similar to replacing the roll of paper; make sure to feed it past the heating element, or the printer won’t work properly. Your printer’s manufacturer should include any special instructions for installing a new ribbon. © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved
