6. Which factor affects the speed of an inkjet printer?

  • the desired quality of the image
  • the size of printer power supply
  • the quality of the paper
  • the cost of the inkjet cartridges
The speed of an inkjet printer is determined mostly by the make and model of the printer, the quality of printing, and the complexity of the image. The quality of the paper, the cost of the cartridges, and the size of the power supply do not affect the speed of printing.

7. What is a characteristic of thermal inkjet nozzles?

  • The heat creates a bubble of steam in the chamber.
  • Heat is applied to the ink reservoir of each nozzle.
  • The vibration of the crystal controls the flow of ink.
  • A charge is applied to the printhead.
Thermal inkjet nozzles work based on heat creating steam bubbles. Piezoelectric inkjet nozzles work based on vibration of crystals.

8. In laser printing, what is the name of the process of applying toner to the latent image on the drum?

  • developing
  • charging
  • transferring
  • fusing
The toner is applied to the latent image on the drum during developing. The toner attached to the latent image is transferred to the paper during transferring. The toner transferred is melted to the paper during fusing, and the drum gets a uniform negative charge during charging.

9. What is the purpose of the Additional Drivers button in the Sharing tab of the Printer Properties?

  • to add additional drivers for other operating systems
  • to add additional drivers for other printers in the network
  • to add additional drivers for duplex printing
  • to add additional drivers for other printers connected to the computer
The Additional Drivers button loads drivers in the sharing computer for other operating systems that the client computers may be running. For other printers in the network, the drivers must be loaded in the computers sharing the other printers. There is no need for additional drivers for duplex printing. The required drivers for other printers connected to the sharing computer will be loaded automatically.

10. A Windows 7 computer has several printers configured in the Control Panel Devices and Printers window. Which printer will the computer choose to be the first option for printing?

  • the printer that is set as the default printer
  • the software-based printer that is used to create PDF files
  • the software-based printer that is used to create XPS files
  • a manual selection, which is always needed
The Default Printer option is set globally and it will be the first printer to be chosen to print a job, unless Other Printer is selected in a Per-Document manner. Software-based printers are just instances of different kinds of printers, but for them to be chosen to do the job, they will need to be selected either as a default or per-document printer. There is no need to select a printer every time a printing job is sent.

11. Which type of print server provides the most functions and capabilities?

  • a dedicated PC print server
  • a computer-shared print server
  • a hardware print server
  • a print server that is implemented in software
A dedicated PC print server has its own resources for the job and can manage several printers. A computer-shared print server uses its resources for sharing as well as for its own PC tasks. A hardware print server can only manage one printer, and a software print server cannot exist without hardware to run it.

12. A user discovers that an inkjet color printer is printing different colors from those that are shown on the screen. What can be done to solve this problem?

  • Calibrate the printer.
  • Adjust the printer spool.
  • Replace the fuser.
  • Replace the drum.
Calibrating the printer will align the heads and help in dosing the ink. The print spool problems are more related to queues. Color inkjet printers do not use drums or fusers.

13. What is a characteristic of global and per-document options in print settings?

  • Per-document options override global options.
  • Global options take precedence over per-document options.
  • It is not possible to configure per-document options.
  • It is not possible to configure global options.
Global settings act as default settings, whereas per-document settings are helpful with specialized documents, like letters and spreadsheets.

14. After applying a solution to a printer problem, a technician restarts the printer and prints a test page. Which step of the troubleshooting process is the technician applying?

  • verifying the solution and system functionality
  • identifying the problem
  • testing a theory to determine the cause of the problem
  • documenting findings, actions, and outcomes
Testing a printer by restarting it and printing a test page are actions taken within the verification of the solution and system functionality step.

15. A technician recorded that a new fuser roller unit was installed in a laser printer to solve a printing problem. Which step in the troubleshooting process did the technician just perform?

  • documenting findings, actions, and outcomes
  • verifying the solution and system functionality
  • identifying the problem
  • testing a theory to determine the cause of the problem
Recording the components and parts used to fix a printer problem is part of the documenting findings, actions, and outcomes step.

16. Which action supports an effective printer preventive maintenance program?

  • Reset the printer page counters if available.
  • Replace laser printer toner at set predetermined time intervals.
  • Clean inkjet print heads when they stop working.
  • Disconnect the printer from the power source when it is not in use.
Resetting the page counters will assist in documenting printer usage and planning future maintenance. Cleaning parts only when they are no longer working, replacing consumables at set time intervals regardless of need, and disconnecting the printer from the power when it is not in use are not related to a preventive maintenance program.

17. How can the life of a thermal printer be extended?

  • Clean the heating element regularly with isopropyl alcohol.
  • Clean the inside of the printer with a vacuum cleaner with a HEPA filter.
  • Keep the paper dry in a low humidity environment.
  • Wipe the outside of the printer with a damp cloth.
The life of a thermal printer can be extended by cleaning the heating element regularly with isopropyl alcohol. A thermal printer does not use toner, so cleaning with a vacuum cleaner with a HEPA filter is not necessary. The condition of the paper and the cleanliness of the outside of the printer would probably do little to extend the life of the printer.

18. In Windows 8, what must be configured to enable one user to share a USB-connected printer with another user on the same network?

  • Windows firewall
  • Windows Defender
  • IEEE 802.11
  • File and printer sharing
  • virtualization option in BIOS
In both Windows 7 and 8, use the ​Network and Sharing Center control panel > Change advanced sharing settings to select the Turn on file and printer sharing option.

19. The users on a LAN are reporting that computers respond slowly whenever high resolution photographs are being printed on the color laser printer. What would be the cause of this problem?

  • The printer does not have enough memory to buffer an entire photograph.
  • The printer is not configured for duplex printing.
  • The paper is not adequate for photograph printing.
  • The printer is not configured for the proper paper orientation.
Printer memory affects print speed and efficiency. Laser printers use memory to buffer print jobs, capturing them in printer memory while allowing computers to proceed with other work while printing.

20. A technician is installing a printer that will be directly connected to a computer. Why does the technician not connect the printer initially during the installation process?

  • The printer needs to be configured first.
  • The OS of the workstation needs to be updated first.
  • The printer driver might need to be installed first before the printer is connected.
  • The Microsoft download site needs to be searched first for the printer driver.
When installing a new printer that is attached directly to a workstation, a technician should read the installation instructions carefully. For some printers, the printer driver should be installed on the computer before the printer is connected.

21. Which statement describes a printer driver?

  • It is the interface in Windows that identifies a unique printer attached to the workstation.
  • It is cache inside a printer that stores documents to be printed in a queue.
  • It is software that converts a document into the format that a printer can understand.
  • It is the configuration code that is sent to a printer to identify the operating system of the workstation.
Printer drivers are software programs that convert various media types in a document to a stream of commands in a language that the printer can understand. During a printer installation, Windows links an interface called “printer” with a specific driver that is compatible with the actual printer hardware.

22. What type of connection would be used to connect a printer directly to the network?

  • Ethernet
  • serial
  • USB
  • Firewire
To connect a printer directly to the network an Ethernet connection through an RJ-45 interface would be used.

23. What mechanism is used in a laser printer to permanently fuse the toner to the paper?

  • heat
  • electrical charge
  • pressure
  • light
Heat is used during the fusing process in a laser printer to permanently fuse the toner to the paper.

24. What corrective action would a technician take in response to a print spooler error?

  • reboot the printer
  • restart the print spooler
  • update the printer driver
  • clean the printer
Print spooler errors can occur when the printer service is stopped or not working properly. The first corrective action is to restart the print spooler. In some cases, it may be necessary to reboot the computer.

25. What corrective action should be taken if a printer is printing faded images?

  • secure loose printer cables
  • update the print driver
  • clean the printer
  • replace the toner cartridge
If a printer is printing faded images, it is an indication that either the toner is low or the toner cartridge is defective.

26. What would cause an inkjet printer to fail to print any pages?

  • The printer software is set to toner save.
  • The printer ribbon is worn out.
  • The ink cartridge is empty.
  • The printer is loaded with a paper type other than photo paper.
An inkjet printer will commonly fail to print when the inkjet cartridge is empty.

27. A user tells a technician that the printer does not respond to attempts to print a document. The technician attempts to print a document and the printer does not output any pages. The technician notices that the printer LCD display is blank and unlit. What is most likely the problem?
