Which laser printer component protects a fuser from overheating?

Answer:  a thermal fuse.  Thermal fuses keep fusers from overheating.  A thermal fuse is designed to open when it is heated to a particular temp. Thermal fuses must be replaced when the fuse opens, or blows.  Fusers, which use heat and pressure to cause toner to melt or fuse to the printed media, are subjected to high temperatures during normal operation.

The images printed from your laser printer are too long or too short.  What is the possible cause of this problem?


Answer:  A problem with the drive motor exists.  The drive motor is responsible for the smooth movement of paper through the printer.  If the drive motor does not move the paper at the required speed, the printed images can appear too long or too short.

Grinding noise coming from the computer

  1. Conor calls you because his computer starts to slow down about 30 minutes after he logs on. He tells you that he can hear a grinding noise coming from the computer. You want to determine if the noise is related to insufficient physical memory. Which Memory performance counter should Conor monitor?
Page faults/sec. A page fault occurs whenever the operating system accesses the hard disk for contents that could not be stored in physical memory. The space on the hard disk that stores the contents is referred to as virtual memory. By having Conor monitor the rate at which page faults occur, you can determine whether the grinding noise, which is likely coming from the hard drive, is related to insufficient memory. When the page fault increases to about 5 per second, there is likely a memory bottleneck.

Offline files and synchronization

Call us at (516) 313-1077


  1. You are a DST, and Sammy, the marketing manager has a shared folder that all salesmen must access. The file is enabled with offline access. Adina, an employee, began working at home Mondays, Tuesdays, and Wednesdays. She accesses the network with a VPN connection. When she is not on the network, she accesses the offline files. Today is Wednesday. Last Friday, Sammy created a file named client.xls. On Monday, Adina logged onto the network and made changes to the file. On Tuesday, Sammy made more changes to the file. Adina did not access the file on Tuesday. What will happen when Adina logs onto the network today?



Adina will be asked what copy of the file she wants to use. Synchronization checks the state of both the cached and the shared file. If both have changed, the user will be asked which one they want to keep.

Offline files and encryption

Flowchart for the operation of EFS (Encrypting...Image via Wikipedia
Today a customer called with a question, "we use offline files on our file server and computers so that our remote users can access files when they are not connected to the network. I found this one file that should be available only to the CEO, so I am thinking of encrypting it rather than configuring access permissions. Will users be able to access the file?"

Users will continue to be able to access the cached file because the encrypted file will not be synchronized. When a file is encrypted, only the user who encrypted the file, can access it. The encrypted file will not be synchronized. The file will only be synchronized when the person who encrypted it is logged on.

  1. George has a problem with his camcorder. The camera is attached to the computer using a USB cable. When the computer is turned on, the camcorder comes on automatically. But, when the computer is turned off, the camcorder does not turn off. What tool or Control Panel applet will accomplish the goal of turning off the camcorder when the computer shuts down?
Device Manager. Open the Properties dialog box for the camera or the USB root hub, and click the Power Management tab. The tab contains two options. One configures whether to turn off the device when the computer shuts down and the other defines whether the device can bring the computer out of standby mode. Once the root hub is configured, all the devices attached to the USB hub will be affected by the configuration.

The documents folder on the C drive has the Modify permission and the documents folder on the D drive had the Read and Execute permission. Which permission will be granted to Jill on the copy?
