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
