1 / 22

What does the imaging drum do in a laser printer?

Stores the toner for printing

Cleans the printed page

Writes or paints the image on the piece of paper

Regulates the heat in the printer

2 / 22

What is the role of the fuser assembly in a laser printer?

Applying negative charge to the photosensitive drum

Cleaning any excess toner from the photosensitive drum

Transferring toner from the drum to the printed page

Melting the toner to the paper using heat and pressure

3 / 22

What is the purpose of phase five in the laser printing process?

To render the printed page in the memory of the laser printer

To expose the image onto the photosensitive drum using a laser

To apply heat and pressure to melt the toner to the page

To transfer the toner from the drum to the printed page

4 / 22

Which phase involves applying heat and pressure to melt the toner to the paper?

Phase five – Transferring phase

Phase six – Fusing step

Phase three – Exposing stage

Phase four – Developing step

5 / 22

What happens in step two of the laser printing process?

Writing a negative charge to the photosensitive drum

Applying heat and pressure to melt the toner to the paper

Cleaning any excess toner from the photosensitive drum

Using a laser to paint the image onto the photosensitive drum

6 / 22

What is done in phase three of the laser printing process?

Transferring toner from the photosensitive drum to the paper

Using a laser to paint the image onto the photosensitive drum

Applying heat and pressure to melt the toner to the paper

Taking toner from the toner cartridge and having it stick to exposed areas

7 / 22

Which step involves taking toner from the toner cartridge and having it stick to the areas exposed by the laser?

Phase seven – Cleaning phase

Phase five – Transferring phase

Phase four – Developing step

Phase six – Fusing step

8 / 22

What is the purpose of step seven in the laser printing process?

To transfer the toner from the photosensitive drum to the paper

To expose the image onto the photosensitive drum

To clean any excess toner from the photosensitive drum

To apply heat and pressure to melt the toner to the paper

9 / 22

Why are freshly printed pages from a laser printer slightly warm?

Because of the rendering of the page in memory during phase one

As a result of transferring toner from the drum to the paper in phase five

Because excess toner is still on the photosensitive drum

Due to the application of heat and pressure during phase six

10 / 22

What happens in phase six of the laser printing process?

Applying heat and pressure to melt the toner to the paper

Cleaning any excess toner from the photosensitive drum

Exposing the image onto the photosensitive drum

Transferring the toner from the photosensitive drum to the paper

11 / 22

What is the purpose of phase five in the laser printing process?

To transfer the toner from the photosensitive drum to the paper

To clean any excess toner from the photosensitive drum

To apply heat and pressure to the toner

To melt the toner to the paper

12 / 22

What is done in the processing step of the printing process in a laser printer?

The laser writes the image onto the photosensitive drum

The photosensitive drum is cleared and prepared for the image to be written by the laser

Toner is attracted to the areas of the drum where the image has been exposed

Data is sent to the printer, and the image is rendered in memory before printing begins

13 / 22

What is the purpose of the cleaning step in the printing process of a laser printer?

To apply heat and pressure to permanently affix toner to the paper

To print on both sides of a page

To pick up and send one page at a time through the printing process

To clean and prepare the drum for the next printing cycle

14 / 22

What is the function of the transfer belt and roller in color laser printers?

To combine and transfer toner from individual cartridges onto a single page

To clean and prepare the drum for the next printing cycle

To pick up and send one page at a time through the printing process

To print on both sides of a page

15 / 22

What happens in the developing step of the printing process in a laser printer?

Data is sent to the printer, and the image is rendered in memory before printing begins

The laser writes the image onto the photosensitive drum

The toner is transferred to the paper

Toner is attracted to the areas of the drum where the image has been exposed

16 / 22

What is duplexing in the context of a printer?

Printing on both sides of a page

Cleaning and preparing the drum for the next printing cycle

Picking up and sending one page at a time through the printing process

17 / 22

What is the role of the pickup roller in a laser printer?

Combining and transferring toner from individual cartridges onto a single page

Printing on both sides of a page

Picking up and sending one page at a time through the printing process

Cleaning and preparing the drum for the next printing cycle

18 / 22

What is the function of the fuser assembly in a laser printer?

It applies heat and pressure to melt and permanently affix toner to the pape

It picks up and sends one page at a time through the printing process

It cleans and prepares the drum for the next printing cycle

It combines and transfers toner from individual cartridges onto a single page

19 / 22

Why is it important for a technician to be familiar with the laser printing process?

To handle high voltages safely

To know how to access and replace the imaging drum

To understand how to create high quality output

To clean and maintain the printer regularly

20 / 22

What happens when you replace the toner cartridge in a laser printer?

You clean and maintain the printer

You replace the high voltage components

You replace the imaging drum only

You also replace the imaging drum

21 / 22

Why is a laser printer suitable for an office environment?

It has a relatively complex process

It creates high quality output

It uses powdered toner

It combines high voltages with heat and pressure

22 / 22

What is the purpose of the imaging drum in a laser printer?

To heat the powdered toner

To clean and maintain the printer

To transfer toner to the paper

To create high voltage for printing
