Course ILT Printers Unit objectives Identify features of dot-matrix printers Install, use, and troubleshoot inkjet printers Install, use, and troubleshoot laser printers Identify other printer types Course ILT Topic A Topic A: Dot-matrix printers Topic B: Inkjet and related printer technologies Topic C: Laser printers Topic D: Other types of printers Course ILT Dot-matrix printer Impact printer 9 or 24 pin print head Various size and shape ribbon cartridges Tractor feed and friction feed Serial or parallel connections Course ILT Other impact printers Daisy wheel Band printer Course ILT Dot-matrix printer issues Print head Ribbon Overheating Paper jams Other problems – – – – – – Printer drivers Error messages Memory Configuration Connections Print quality Course ILT Options and upgrades Paper park Input and output trays Font cartridge slots Paper cutters Course ILT Activity A-1 Examining the dot-matrix print process Course ILT Topic B Topic A: Dot-matrix printers Topic B: Inkjet and related printer technologies Topic C: Laser printers Topic D: Other types of printers Course ILT An inkjet printer Course ILT Inkjet process Thermal bubble technology Piezoelectric technology Ink cartridges Dithering Print heads Course ILT Inkjet printer cartridges Course ILT Inkjet cartridge print heads Inkjet print quality Course ILT Affected by: – DPI of the printer – Quality of the paper – Quality of the ink if printed page gets wet Course ILT Straight-through paper path Course ILT Curved paper path Course ILT Inkject photo printers Don’t hold up as long as traditional, chemically produced dark-room photos Special paper required Use regular paper = lower quality prints Can print on non-paper items Course ILT Printing on non-paper surface Course ILT Activity B-1 Examining how inkjet printers work Course ILT Inkjet printer installation Connect via USB Windows autodetects and installs drivers Can install additional software from manufacturer Course ILT Ink level utility Course ILT Printer interfaces USB Parallel SCSI Serial Inkjet communications interfaces Course ILT Parallel interface USB interface Course ILT Configure connection type SCSI — assign a unique device ID Parallel — Specify the correct LPT port Serial — Specify the correct COM port Course ILT Parallel port in Device Manager Course ILT Installing an inkjet printer 1. Connect the printer to a computer using the correct interface 2. Plug it in 3. Power it up 4. Windows will likely recognize you’ve connected a new device and install drivers for it automatically 5. If drivers aren’t installed automatically, you can do it manually using the materials that shipped with the printer Course ILT Activity B-2 Installing an inkjet printer Inkjet printer maintenance Course ILT Consumables – Paper – Ink levels Color matching Environment Safety Course ILT Optimization Paper trays/orientation Print spool settings Course ILT Troubleshooting Acquire information about the problem Simplify by removing any non-critical components, shut down unnecessary running programs, and disconnect from the Internet or network. Implement by identifying probable causes and implementing potential solutions one at a time. Document the error symptoms, the components you removed from the computer, and the solutions you tried and whether they were successful. Course ILT Inkjet problems Cost of consumables Nothing prints Poor print quality or stray lines Paper jams Course ILT Activity B-3 Troubleshooting inkjet printer problems Course ILT Topic C Topic A: Dot-matrix printers Topic B: Inkjet and related printer technologies Topic C: Laser printers Topic D: Other types of printers Course ILT Laser printer Course ILT Laser printer components Toner cartridge Laser scanning assembly Power supplies Paper control and transport assembly Transfer corona assembly Fusing assembly Electronic control package Course ILT Toner cartridge Course ILT Laser scanner assembly Laser Mirror Lens(es) Course ILT Laser print process Charging or conditioning Writing or exposing Developing Transferring Fusing Cleaning and erasing Course ILT Laser print process (con’t) Course ILT Activity C-1 Examining how laser printers work Unpacking Course ILT Toner is removed – Gently roll toner cartridge side to side Install drum Remove styrofoam from toner area Remove packing tape Install toner cartridge Course ILT Laser printer interfaces Parallel SCSI USB Serial IEEE 1394/Firewire Wired or wireless Ethernet network Infrared ports Course ILT Communications interfaces Course ILT Install a laser printer 1. Connect the printer to the network or a computer using the correct interface 2. Plug it in 3. Power it up 4. Windows will likely recognize you’ve connected a new device and install drivers for it automatically 5. If drivers aren’t installed automatically, you can do it manually using the materials that shipped with the printer Course ILT Activity C-2 Installing a laser printer Course ILT Printer configuration options Orientation Collation Copies Quality Color Order Switch print trays Spool settings Some configuration can be done through buttons on printer itself Course ILT Activity C-3 Configuring a Windows printer Course ILT Laser printer problems Safety issues Paper jams All or nothing Partial prints and smudges Repeating marks and stray marks Garbage prints Course ILT Activity C-4 Troubleshooting laser printer problems Course ILT Topic D Topic A: Dot-matrix printers Topic B: Inkjet and related printer technologies Topic C: Laser printers Topic D: Other types of printers Course ILT Other printer types Solid ink Dye sublimation Thermal – Thermal wax transfer – Direct thermal – Thermal autochrome Course ILT Plotters Create line images Use pens Often available in large format for CAD drawings Draws smooth lines and curves Course ILT Additional printer types Snapshot printers Large format printers Art printers Course ILT Activity D-1 Identifying other printer technologies Course ILT Unit summary Identified features of dot-matrix printers Installed, used and troubleshot inkjet printers Installed, used, and troubleshot laser printers Identified other printer types
