Lesson 9: Supporting Print Devices

Multifunction Devices (MFDs)

Devices that perform printing, scanning, and faxing.

Printer Languages

Communication protocols, such as PCL (HP) and PostScript (Adobe), used by printers.

USB Connectivity

Allows printers to connect to computers using Type A (computer) and Type B (printer) connectors.

Duplex Printing

Printing on both sides of the paper.

Laser Printers

Printers known for high-quality output and fast printing, ideal for office environments.

Components of Laser Printers

Include Imaging Drum, Fuser Assembly, Transfer Belt, Pickup Roller, and Separation Pad.

Seven-Step Process of Laser Printing

Steps include Processing, Charging, Exposing, Developing, Transferring, Fusing, and Cleaning.

Inkjet Printers

Common and inexpensive printers for home use, known for quiet operation and color output.

Challenges of Inkjet Printers

Include costly cartridges, ink fading, and tendency to clog.

Thermal Printers

Printers that use heat on coated paper instead of ink or toner.

Disadvantages of Thermal Printers

Output can fade with heat, making them unsuitable for long-term archiving.

Impact Printers

Printers that create output by striking a ribbon against paper, such as dot matrix printers.

Cost Efficiency of Dot Matrix Printers

Low page cost, making them good for multi-copy printing.

3D Printers

Printers that create three-dimensional objects using technologies like Filament Printing (FDM) and Stereolithography (SLA).

Troubleshooting Printer Output Issues

For Inkjet: clean or replace print heads; for Laser: inspect drum for damage.

Print Queue Maintenance

Clear corrupted print jobs and restart the print spooler to resolve issues.

Mechanical Issues in Printers

Check for jamming, grinding sounds, and proper installation of ink cartridges.

A printer support technician at a corporate office receives a call from the administrative office that their printer is showing online, but nothing is printing out. When checking the print server, there are multiple documents queued for the printer. What type of error is this?

Print spooler issue

An employee prints documents and photos on the office inkjet printer, but they are printing in the wrong color. What is the correct maintenance step the employee needs to perform on the printer?

Ink cartridge replacement

When printing to a multifunction printer, the printer staples the pages sideways. What type of error is this?

Incorrect page orientation

A printer support technician at a corporate office receives a call from the administrative office that the office inkjet printer is online but it is making a grinding noise while printing. What type of error is this?

Carriage mechanism fault

A support technician at a corporate office needs to recommend a new laser printer for the administrative office. The office personnel requests a printer that will automatically print on both sides of the paper. What does the technician need to look for to make the proper decision on which printer to purchase?

Duplex unit

What type of printer builds a solid object from successive layers of material?

3D printer

When an employee prints to a newly installed printer, the printed pages only have a few characters on each page. What type of error is this?

Garbled print issue

A support technician at a corporate office needs to recommend a new laser printer for the administrative office. The office personnel requests a printer they will not have to refill with paper as often as their current printer. What does the technician need to look for to make the proper decision on which printer to get?

Input tray capacity

A support technician at a corporate office needs to recommend a new laser printer for the administrative office. The office prints multiple types and sizes of documents, labels, envelopes, and other materials. What does the technician need to look for to make the proper decision on which printer to get?

Paper handling

A support technician at a corporate office needs to recommend a new laser printer for the administrative office. One of the considerations is the speed of the printer. How is the basic speed of a printer measured?

Pages per minute (PPM)

A printer support technician at a corporate office receives a call from the administrative office that their laser printer is online, but office employees can not print. When examining the printer, the technician finds paper lodged in the fuser unit. What type of error is this?

Paper jam

An employee receives a brand-new inkjet printer. The output prints documents and photos that appear skewed. What is the correct maintenance step the employee needs to perform on the printer?

Print head alignment

A support technician at a corporate office needs to recommend a new multifunction printer for the administrative office. Since the office commonly prints and scans photos and high graphic items, the technician needs to select a multifunction printer that will meet this need. What characteristics should the technician review to choose the correct multifunction printer? (Select all that apply.)

• Dots per inch (DPI)

• Pixels per inch (PPI)

What type of printer uses a heating element to create images on paper?

Thermal printer

The office inkjet printer is missing lines when it is printing. What is the correct maintenance step that needs to be performed in the printer?

1. A.Print head alignment

2. B.Print head cleaning

3. C.Load roller replacement

4. D.Eject roller replacement
