When a laser printer is turned on, the first component that is activated is the laser. The laser beam passes through a series of mirrors and lenses before it reaches the photosensitive drum. The drum is coated with a light-sensitive material that is charged by the laser beam.
The charged areas of the drum are attracted to the paper that is fed into the printer. The paper is then passed through a series of rollers that transfer the image from the drum to the paper.
The charge corotron is the component in a laser printer that prepares the photosensitive drum for writing. The charge corotron charging system consists of a high voltage power supply, a corona wire, and a ground electrode. The corona wire is located between the power supply and ground electrode, and it emits a high-voltage, high-frequency field.
This field causes the photo-conductive drum to become positively charged. The ground electrode is located on the side of the drum opposite the corona wire, and it helps to maintain the drum at a constant potential.
Which component in a laser printer apply toner to the drum?
Laser printers work by using a laser to draw an image of the page onto a drum. The drum is then coated with toner, which is a powder that contains the pigment that will be used to print the image. The toner is attracted to the charged areas of the drum, and when the drum is rotated, the toner is transferred to the paper.
The component in a laser printer that applies toner to the drum is called the toner cartridge. The toner cartridge is a replaceable component that contains the toner powder. When the toner cartridge needs to be replaced, you can simply remove it from the printer and replace it with a new one.
Which printer part gets the photosensitive drum to the paper?
Assuming you are talking about a laser printer:
The printer part that gets the photosensitive drum to the paper is the transfer belt. The transfer belt is a cylindrical belt that is located between the photosensitive drum and the paper.
The belt is coated with a material that is electrically charged. When the photosensitive drum is charged with an electrical current, the charged particles on the surface of the drum are attracted to the charged particles on the transfer belt. This causes the particles on the drum to be transferred to the belt.
The belt then transports the particles to the paper, where they are deposited and fused to the surface of the paper.
Which component of the laser printer is responsible for making the image permanent on the paper?
The component of the laser printer that is responsible for making the image permanent on the paper is the fuser assembly. The fuser assembly melts the toner onto the paper, which makes the image permanent.
What is the role of photosensitive drum in laser printer?
When a laser printer prints, the photosensitive drum is responsible for transferring the image onto the paper. The drum is coated with a light-sensitive material that is activated by the laser. The laser beam “draws” the image onto the drum by selectively exposing the light-sensitive coating to the laser beam.
The exposed areas are then developed, which means that they are turned into a charged image. The charged image is then transferred onto the paper.

Which of the following are printer languages? (select three).
There are a few different printer languages out there, each with their own benefits and drawbacks. The three most popular printer languages are PostScript, PCL, and ESC/P.
PostScript is a page description language developed by Adobe.
It is the industry standard for commercial printing, and is supported by nearly all professional printers. PostScript files are usually generated by design or layout programs such as Adobe InDesign or QuarkXpress. PCL is a page description language developed by Hewlett-Packard.
It is less expensive to implement than PostScript, and thus is found in many lower-end printers. PCL files can be generated by a variety of programs, including Microsoft Word. ESC/P is a page description language developed by Epson.
It is similar to PCL in that it is less expensive to implement, but it is not as widely supported as PostScript or PCL.
Which type of printer uses an inked ribbon?
If you’re looking for a printer that uses an inked ribbon, you’re likely looking for a dot matrix printer. Dot matrix printers are one of the oldest types of printers still in use today, and they work by striking an inked ribbon against the paper to create the desired print.
Dot matrix printers are most commonly used for printing things like invoices and other documents where a clean, high-quality print isn’t required.
They’re also relatively inexpensive, making them a popular choice for budget-conscious consumers. If you’re looking for a dot matrix printer, be sure to shop around to find the best price. You can often find them for under $100, and they’ll last for many years with proper care.
Which of the following allows a computer to communicate with a printer?
Assuming you would like a blog post discussing the various ways a computer can communicate with a printer:
Most people are familiar with the standard method for connecting a printer to a computer, which is to connect the two devices using a USB cable. However, there are actually several different ways that a computer can communicate with a printer.
In addition to using a USB cable, you can also connect your printer to your computer using a wireless connection. This is convenient if your printer is located in a different room from your computer, or if you want to be able to print from multiple computers. Another option for connecting your printer to your computer is to use an Ethernet cable.
This is a good choice if you have a fast Internet connection and want to be able to print quickly. Finally, you can also connect your printer to your computer using Bluetooth. This is a good option if you want to be able to print from your mobile device.
Which of the following is the most likely symptom of a dirty drum or roller in a laser printer?
A dirty drum or roller in a laser printer is most likely to cause poor print quality. This can manifest as streaks, smears, or spots on the printed page. The issue can generally be resolved by cleaning the drum or roller.
Which of the following printer connections would best facilitate multiple user access?
If you’re looking to facilitate multiple user access to a printer, you’ll want to go with a networked printer connection. This will allow multiple users to connect to the printer and use it simultaneously. There are a few different ways to set up a networked printer, so be sure to consult your printer’s documentation to find the best method for your needs.
In a laser printer which cartridge needs replacing most often
If you own a laser printer, you know that sometimes cartridges need to be replaced. But which cartridge needs replacing most often?
The answer may surprise you.
It’s actually the black cartridge that needs replacing most often. This is because laser printers use more black toner than any other color. So, if you have a laser printer, be sure to keep a spare black cartridge on hand.
That way, you can replace it as soon as it starts to run low.
Which of the following printer types is considered an impact printer?
An impact printer is a type of printer that uses a hammering action to create an image on paper. The most common type of impact printer is the dot matrix printer, which uses a row of small pins to strike the paper and create dots. Impact printers are generally slower than other types of printers, but they are less expensive.
Which of the following types of printers heats the ink in its print head to print?
There are a few types of printers that heat the ink in its print head to print. The most common type of printer that does this is an inkjet printer. When the inkjet printer heats the ink, it causes the ink to expand and then be ejected onto the paper.
This type of printing is very efficient and is commonly used for printing photographs and other high-quality images.
The photosensitive drum is the key component in a laser printer that allows it to produce high-quality prints. This drum is coated with a light-sensitive material that is charged by the laser beam. When the laser beam hits the drum, it discharge the areas that are to be printed, which attracts the toner.
