The key parts of the printer include, toner cartridges, image drum (also known as drum unit or photo-conductor), transfer roller or belt, fuser unit, laser, and mirrors.
LaserJet as a brand name identifies the line of laser printers marketed by the American computer company Hewlett-Packard (HP). The HP LaserJet was the world`s first desktop laser printer. Canon supplies both mechanisms and cartridges for most HP laser printers; some larger A3 models use Samsung print engines.
If toner stains or black streaks appear, wipe the paper transfer roller with a rag or other dry cloth. Do not use water or any alcohol-based solvent. Clean the paper transfer roller until there is no visible dirt or dust on the roller.
The toner cartridge is the container that holds the toner powder. The drum unit is an electrically charged cylinder that fuses that toner powder onto paper to create text and images. Both of these components are essential for producing a print.
An image drum is a critical component of a laser printer that transfers toner and image or text to paper. It`s also known as the image unit, drum unit, or photoreceptor drum, among other things.
Laser printers can print faster than inkjet printers. It won`t matter much if you print a few pages at a time, but high-volume users will notice a huge difference. Laser printers produce perfect sharp black text. If your print jobs are mostly text with occasional graphics, laser is the way to go.
Laser printers can print much faster than inkjet printers can. Most are equipped with high-capacity paper trays, so they can print more pages at a given time. They`re also built to handle the printing of thousands of pages per month without succumbing to wear-and-tear.
“HP`s Officejet Pro X 500 series is recognised as the world`s fastest desktop printer by Guinness World Records. It is powered by HP PageWide Technology and can deliver professional documents at up to 70 pages per minute,” HP Printing Systems PPS Director Nitin Hiranandani told reporters here.
Laser printer is known to be the fastest printer. It is a type of printer linked to a computer producing good-quality printed material by using a laser to form a pattern of electrostatically charged dots on a light-sensitive drum, which ink powder.
Use isopropyl alcohol or ethanol according to the manufacturer`s safety guidelines, as applicable. Wipe the roller with a lint-free cloth dipped in isopropyl alcohol or ethanol. After cleaning the roller, make sure that no lint or other material remains on the roller.
Excessive shaking or dropping it onto a hard surface could damage your cartridge irreparably. Meddling with the cartridge`s cover or pulling out a cartridge while the printer is in use are both usually bad ideas.
Therefore, try to shake your new toner cartridges before you install it. Hold both ends of the toner cartridge, and shake it slowly and horizontally for 5~6 times. The powder in the toner cartridge should be shaken loose and evenly distributed, which is conducive to uniform printing color.
Step 4: Exposing

Every area of the drum exposed to the laser has its surface charge reduced to about 100 volts DC. An invisible latent print is generated as the printer`s drum turns. The image that will ultimately be printed exists for the first time as a thin layer of electrons on the OPC drum.

Quality: While inkjet printers are considered powerhouses when it comes to high-resolution color printing, laser printers do produce solid color and black and white results.
4-Color Process uses Cyan, Magenta, Yellow, and Black inks. When applied in successive layers, these four ink colors create a full color image. 4-Color Process is the most widely used method for printing full-color images.
The drum unit may need replacing if you notice the printer producing blurry, low-quality images. Black or colored toner spots on printouts also indicates a failing drum unit. In some cases, horizontal lines may develop across the printout every time the paper passes the failing part of the drum.
The most obvious is most common on laser color printers and can be detected by a flashing message on the printer display screen. Other signs of a bad printer drum include printing blank pages, printing gray pages and strange sounds coming from the printer as it prints.
Toner is the powder ink that latches on to the paper to create text and images. It is stored in the toner cartridge. An image drum is the unit that copies the text and images from the computer and then transfers them to the paper, along with the toner.
What is the drum unit? The drum unit transfers the toner to the paper. The laser printer puts the toner on the roller called “The photosensitive drum” inside the drum unit, and then prints letters and images by fixing toner to the paper by heat and pressure.
Color Laser Printer or Black & White Laser Printer

As print quality goes down over time, this will be a reason to replace the color printer. We find a black and white printer can sometimes last 10 years or more and most color laser printers are replaced every 3 to 5 years.

Typically, laser printers are the most efficient in terms of ink in that a single toner can last for a few years if you only occasionally print — HP`s Neverstop Laser 1001nw`s toner can last for up to 5,000 printed pages, for example.
Inkjet printers typically run at a lower price point than laser printers, and printer ink is cheaper than toner. However, laser printers and toner have a longer lifespan despite their high cost. Meaning laser toner cartridges have a lower cost per printed page than printer ink.
Although toner cartridges are more expensive than ink cartridges, they last much longer — making laser printing a more cost-effective option in the long run if you do a lot of printing. A standard toner cartridge prints about 2,000 to 3,000 pages, compared to an inkjet cartridge that yields 200 to 300.
More affordable for high-volume print users

While ink is still relatively expensive to refill or replace, toner powder is much more affordable over time. This also makes it more efficient and less wasteful because inkjet cartridges often force users to refill or replace them before they`ve been completely depleted.
