You are having problems with Internet Explorer. When you visit a website, old pages seem to appear. At first, you thought the websites were not being updated, but then you checked the websites on another computer, and saw that the pages were different. What should you do to correct the problem?

On the General tab of Internet Options, in the Temporary Files section, click on the Settings tab. Four options are available to set for Internet Explorer to check for new web pages: Every visit to the page, Everytime you start Internet Explorer, Automatically, Never. It is likely you had the selection set to Never.

Local Users and Groups

Active DirectoryImage by arrayexception via Flickr

You hire temps to scan documents and print to a local printer in your office. The temps will be using one computer. Security settings do not permit the temps to access the local printer. The computer is a member of an Active Directory Domain and the all actions performed by the temps must be audited. What actions should be performed to allow the temps to print and to permit auditing of the temps activities?

Create five local user accounts. Because the temps will use only one computer, they will not have accounts in the domain.
Create a local group named Temps. You can then grant the Temps group access to the local printer.
Add each local account to the Temps local group.
Allow each Temp to log on using his or her local account. This allows audit settings to apply to the individual Temps.

 What is the function of the nozzle gate in an inkjet printer?

Answer:  Controls whether ink is flowing from the ink cartridge.  When an inkjet printer starts printing, the nozzle gate opens and allows the nozzle to spray ink onto the paper.  After printing is stopped, the nozzle gate shuts down to stop the flow of ink.

Dot Matrix Printer

What printer type can print multi-part forms?

Answer:  Dot-matrix.  Multi-part forms, often referred to as carbon copies, have two or more sheets of paper per page. The daisy-wheel printer is higher print quality compared to a dot-matrix printer, but the daisy-wheel printer is limited to printing text and the dot-matrix printer can print text and graphics.

Laser printer prints vertical black line

Your laser printer recently began printing a vertical black line near the edge of every printed page.  What should you do to resolve this problem?

Answer:  Replace the toner cartridge.  Toner, the laser equivalent of ink, is a fine powdery mixture of pigment typically made from iron or carbon and an easily melted polymer or wax binder.  When the toner cartridge is almost empty, the laser printer may begin to print a black line on the side of each page.  Another cause of vertical black lines is a scratch on the drum.  The cartridge contains the drum.
