55
Laser printer maintenance
Loading paper, Toner Cartridges Replacement, Use Maintenance Kit, Page Count and Calibration, Cleaning the printer,
56
Loading paper Laser printer maintenance
Loading Paper: Buy paper rated for that type of printer. Using the wrong paper can cause paper jams. Store the paper in a nice dry area that does not have high humidity or excessive dust.
57
Toner cartridges replacement
Toner Cartridges Replacement: Standard Toner Cartridge has 2500 pages. High-yield Cartridges have 6000 pages
58

59
Page count and calibration laser printer maintenance
Page Count and Calibration: Page Counter: Indicates when to change either a feed, transfer roller or the fuser unit. Always reset page counter after replacing any component. Calibration: Process by which the printer determines the print density or color balance to use.
60
Cleaning laser printer maintenance
Cleaning the printer: Cleaning the components of loose toner, using a damp soft cloth or a toner safe vacuum. Wash with COLD WATER if toner gets on your skin. Some printers have filters for catching dust and dirt needs to be cleaned out as well.
61
Inkjet Printers
Inkjet printer: Creates an image on the paper through a nozzle or jet on a printhead onto the paper. Are the most common in-home office environments. A Laser printer prints the whole page called page based. An Inkjet is printer Line by line.
62
Two main types of inkjet printers
Piezoelectric, Thermal
63
Six components of an inkjet printer
Ink Cartridges, Print Head, Roller, Feeder, Duplex Assembly, Carriage Belt/Carriage System.
64
Inkjet ink cartridges
Ink Cartridges: High-end inkjet printers have seven different cartridges
65
Print Head of an Inkjet printer
Print head: Device that takes the droplets of ink and directs into the paper. Two main technologies for inkjet printers: Piezoelectric method(Charge method): Uses a nozzle that reacts to changes in voltage works like a pump, as more or less voltage is applied the nozzle will change in size to allow more or less out. Does not require to replace the printhead when replacing the ink cartridge. Thermal method(Bubble Jet): Heats up the nozzle in the print head to create an air bubble that sprays ink through the nozzle when it burst, it draws more ink out from the cartridge. Is hard on the printheads, have to replaces printheads when replacing the cartridges.
66
Inkjet printer roller
Roller: Responsible for advancing the paper through the inkjet printer.
67
Inkjet printer feeder
Feeder: Allows multiple pieces of paper in a tray to be selected one pieces of paper at a time and passes it to the roller.
68
Inkjet printer duplex assembly
Duplexing assembly: Allows an inkjet printer to print on both sides of a piece of paper.
69
Inkjet printer carriage belt/carriage system
Carriage belt/Carriage System: Allows the printhead to move back and forth across the page.
70
Two types of Inkjet printing models are
Unidirectional Printing: Printhead will only apply ink from left to right. Bi-directional Printing/Two-Directional Printing: Printhead will apply ink from left to right and from right to left.
71
Inkjet printer maintenance
Loading the paper, Cleaning the heads, Replacing the cartridges, Calibrating the system, clearing paper jams
72
loading paper inkjet printer maintenance
Loading the paper: Inkjet printers have a small single feed tray. Only holding 100-200 pages or 250-500 pages for larger inkjet printers: Open the feed tray Check that the guides are set to the proper paper size Insert paper(align by tapping paper on the desk before restocking) Shut feed tray, system will recognize paper is restocked
73
Cleaning the heads of inkjet printer maintenance
Cleaning the heads: Printheads can get blocked/backed up and dirty. Which causes printer to miss lines or missing colors Run printer through its cleaning cycle if it has one. Can active through the front panel. Or through manufacturer's software installed on the printer driver. Will print out a few pages trying to overheat the nozzle to unblock it. Can buy inkjet cleaning products to clean printheads manually. Printheads are attached to the cartridges in a thermal inkjet print, replacing the cartridges mean also replacing the printhead.
74
Replacing inkjet printer cartridges maintenance
Replacing the cartridges: Most printer manufacturers include a sensor built into inkjet cartridges. Letting you know when to change the inkjet cartridges and when the cartridge is empty. Open the service panel on your printer Usually a retainer clip, push down on retainer clip to pull out empty cartridge and replace with new one. Close try and printer will perform a system check to verify cartridges are proper installed. Printheads are attached to the cartridges in a thermal inkjet print, replacing the cartridges mean also replacing the printhead.
75
Calibrating inkjet printer system for maintenance
Calibrating the system: When the printer output has skewed or missing parts. Again, can either run through front panel or manufacturer's software on the printer driver.
76
Cleaning inkjet printer paper jams
Clearing paper jams: Usually caused by not using the correct paper. Either paper is too light or too thick. If paper is too thick, turn off printer, open service panel. Slowly pull jammed paper through. If paper too light, there will be multiple pieces of paper jammed up. Turn of printer, open service panel. Remove the feeder tray and open the output tray. And try to pull the paper out in whole pages as to not rip paper into smaller pieces. If small pieces get into the tray, might have to use tweezers to remove all the small pieces of paper.
77
Thermal Printer
Thermal Printer: Type of printer that uses a heating element to create an image. Usually smaller in size used to print receipts or photographs. Most thermal printers use thermal paper Gets measured in inches per second/centimeters per second compared to laser and inkjet which are pages per second. Requires: Thermal Paper or Thermal Ribbon Paper-based thermal printers work well in high-speed environments. Example: receipt printer at a restaurant. Thermal Ribbons: Has a mixture of colors (CMYK) and is used to create the heat transfer.
78
Three components of a Thermal Printer

81
Replacing the paper thermal printer maintenance
Replacing the paper: Make sure the paper specific paper for the printer. Open the printer case, insert roll shiny part facing outward, make sure the end of the paper is held in place by the printhead and close the printer case.
82
Cleaning the heating element thermal printer maintenance
Cleaning the heating element: Turn off and remove from power and cool off. Use isopropyl alcohol with cotton swab to clean the printhead.
83
Removing debris thermal printer
Removing debris: Turn off and remove from power and cool off. Take out printer roll. And clean feed mechanism. Small bits of paper and debris can fall back into the feed mechanism.
84
Impact Printers
Impact Printers: are measured based on the quality of the dots. More dots mean higher resolution, most are 100 to 150 dots per inch. Highest resolution is 240 dpi. Tracks: Series of holes going down the side of the paper with a perforation between the regular paper and tracks.
85
Three main components of an Impact Printer
Printhead, Ribbon, Tractor Feed
86
Printhead component of an Impact Printer
Printhead: Device that has a series of pin that make up the dot matrix that forms the image
87
Ribbon component of an Impact Printer
Ribbon: Fabric or material held within a plastic housing in front of the printhead.
88
Tractor Feed component of an Impact Printer
Tractor feed: Exists on both sides of the printer and pulls the paper through the printer using tractor fed paper.
89
Three parts of Impact Printer Maintenance
Replacing the ribbon, Replacing the printhead, Replacing the paper.
90
Replacing the Ribbon Impact Printer maintenance
Replacing the ribbon: Get the specific ribbon for that printer. Once ribbon is out cannot re-use have to throw out fully replace.
91
Replacing the printhead Impact printer maintenance
Replacing the printhead: Printhead dots get worn down. Have to replace when the text will not fully print looking like holes in the text. Buy use the correct specific type of printhead for the printer. Turn off, remove from power, and cool off for an 30 to 60 minutes first.
