3.11 Given a scenario, install and maintain various print technologies. Flashcards
There is a variety of print technologies such as laser, inkjet, thermal, impact, and 3D printers. There are also virtual print options to print to what four file types?

Name the 7 steps of the laser printing process in order.
Processing Charging Exposing Developing Transferring Fusing Cleaning
This stage builds the entire page in memory.
1 - Processing
This stage prepares the drum with negative charge, creating a “blank slate”.
2- Charging
This stage draws the image with the positively charged laser on the drum.
3- Exposing
This stage adds negative charged toner to the imaging drum, sticking only to spots touched with the laser.
4- Developing
In this stage, the transfer roller/transfer belt transfers the toner from the drum to the paper.
5- Transferring
This stage uses heat and pressure to bond the toner to the paper.
6- Fusing
In this stage, any residual toner is cleaned off of the imaging drum.
7- Cleaning
Processing
Before any actual printing is done, the image of the full page in placed into memory.
Charging
A high negative charge is applied to the imaging drum.
Exposing
The laser “draws” the image of the page onto the imaging drum by exposing it to the laser light.
Developing
The negatively charged toner is transferred to the imaging drum. Since the drum is also negatively charged, the toner will only stick to the areas that have been neutralized by the laser.
Transferring
The transfer roller/transfer belt transfers the toner from the drum to the paper.
Fusing
A fusing roller users heat and pressure to bond the toner to the paper.
Cleaning
Any residual toner is cleaned off of the imaging drum.
After processing, the laser “draws” the page image onto the ___.
imaging drum
The ___ applies pressure and heat to bond the toner to the paper.
fuser assembly
Used in color laser printers, the ___ transfers the page image from the imaging drum to the paper.
transfer belt
Used in black-and-white laser printers, the ___ transfers the page image from the imaging drum to the paper.
transfer roller
Rubber ___ feed paper from the paper tray through the printer.
pickup rollers
The ___ ensures that only one page is fed at a time.
separation pad
To print on both sides of the paper, the ___ will flip the paper over.
duplexing assembly
Other printer types don’t need memory, so ___ might cost a little more because of the additional memory installed.
