Understanding Windows Inkjet printers - 1 • Supposedly, there is a second method of getting ink out of the nozzle. • The first is to use a thermistor (or resistor) to heat up the ink to boiling temperature and thus forcing it out the nozzle. • The second method uses pizeoelectrics to shake the ink out of the nozzle. Not sure who uses this method. Inkjet Printers - 2 • Ink clogs in the nozzle area is the major failing of inkjets. • Use them often, the longer they sit, the worse the output • Newer inkjets will go through a (short) cleaning cycle each time they start up. • Most inkjet software includes a Utilities section that contains cleaning and alignment functions. Laser Printers • Toner cartridges have a (shipping) protective tape covering between the toner and drum. • If you forget to remove the tape, you will get blank pages from the printer. Laptops • The wisdom is that you should “calibrate” the battery every so often – maybe once a month. • Charge the battery, disconnect the AC line, boot in Safe Mode and set the system to Always On. • Clock how long the laptop runs before it shuts itself off due to low power. • Over time, this run time will decrease until it is time to replace the battery. POST • POST checks out the basic hardware each time the system boots. • If given a choice of options, the “correct” answer is: CPU, Memory and Video card. • Selecting keyboard is incorrect; I guess because POST only looks for one and does not check keys for proper functioning. Back to Windows • Login screen. You could get away with “Cancel” in Win98, not with 2000 or XP • Most systems don’t have a password on the Administrator account; often you can start up (in Safe Mode) and use that account to reset User password. • There are UNIX boot CDs that will reset (blank) the Administrator password. Find them on the Internet. Desktop • Windows 2000 puts icons for My Computer, My Network Places, My Documents, Internet Explorer and Recycle Bin on the desktop. • XP, in contrast, only puts Recycle Bin. • Use Display Properties to add additional icons Taskbar • Start button, Quick Launch, Running Programs and System Tray (with clock) • Start menu in 2000 is rather one- dimensional: just task areas • Start menu in XP is more two-dimensional: Programs and task areas General Rules of Clicking • Click once (left) on menu item to use it • Left-click icon once to select it • Left-click icon twice to use it • Right-click anything to find Properties option Icons • Programs (.exe files) bring along their own icon(s) • Windows has a collection of icons available • You get Window icon for unknown extensions • Stored in the Registry My Computer • Icon on desktop in 2000; have to add it in XP or access it from the Start button • Displays all the drives on the system (and scanners in XP) • Right-click to get to Properties (and Device Manager) • Last slide.
