How to Identify and Fix Common Problems ?

A laser printer is a popular type of computer printer that uses a non-impact photocopier technology where there are no keys striking the paper. When a document is sent to the printer, a laser beam “draws” the document on a selenium-coated drum using electrical charges.
Color printing uses yellow, magenta, and cyan inks to produce various colors by subtractive mixing to give red, blue, and green. (Each color ink should be thought of as transmitting two of the additive primaries, which is the same as absorbing one of the additive primaries.)
Laser printers use an electrical charge to attract toner particles to a transfer roller. Toner particles are pressed onto a piece of paper, while heat and pressure from the fuser unit permanently fix the image onto the page.
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.
First, the laser printer reads the electronic data that makes up the information or image that you want to print and beams this onto a photo-sensitive drum. The information on the drum is then transferred to paper using static electricity to position tiny particles of powdered toner in the correct pattern.
At the basic level, printers work by converting digital images and text into physical copies. They do this using a driver or specialized software that has been designed to convert the file into a language that the printer can understand. The image or text is then recreated on the page using a series of minuscule dots.
A semiconductor diode laser is currently used in laser printers as the light source.
Laser printers, unlike inkjet printers, do not use ink cartridges. Instead laser printers use toner cartridges, so be sure to purchase accordingly depending on your printer. Toner is a fine dye power that is melted onto the paper.
Laser Printers work with CMYK toners only. inkjet printers and ink printers used for professional photo printing, for example, can use additional colors to achieve better printer results. Among other things, brighter gradations of magenta, cyan and also gray are used.
Laser printers can`t handle a variety of paper or printing materials like inkjets. Anything heat-sensitive cannot be run through them. Home laser printers can handle simple graphics, but smooth photographs are a challenge. If you want to print photos, go for inkjet.
How it works: Laser beams are used to create forces that move a particle of cellulose through the air, while another set of lasers is used to illuminate it. By moving the particle very fast, it`s possible to make what appears to the human eye as a moving image.
Laser prints and photocopies are made with toner instead of ink and use a heat process to set the toner in place. Toner sits on the surface of the paper allowing it to be released when making a transfer.
Basically, a laser traces your document or image onto an electromagnetic canvas, upon which electrically charged particles of toner attach. Toner is a printing material that`s unique to laser printers. It`s advantageous because a single toner cartridge can yield far more pages than an ink cartridge can.
The 3 Steps of the Printing Process
There are three primary stages of commercial printing: prepress, press, and post press. In this section, we`ll explain each step in detail so you can better understand how the print process works.
Portable Network Graphics (PNG) images can contain RGB and indexed color as well as transparency. While PNG can be high resolution, it has no support for the CMYK color space.
RGB colours may look good on screen but they will need converting to CMYK for printing. This applies to any colours used in the artwork and to the imported images and files.
Conclusion. The most significant difference between a laser printer and an inkjet printer is that a laser printer uses dry ink and can produce monochromatic prints only, whereas an inkjet printer uses wet ink and can produce color prints as well.
do the different colors of lasers affect the velocity of the laser light? A: No, the speed of light in a vacuum doesn`t depend on the color (i.e. the wavelength or the frequency). The different colors will travel at slightly different speeds through materials such as glass.
The order of the imaging process in a laser printer is processing, charging, exposing, developing, transferring, and fusing.
Instead laser printers use toner cartridges, so be sure to purchase accordingly depending on your printer. Toner is a fine dye power that is melted onto the paper. Unlike ink, which is sprayed onto paper through fine jets, toner creates a crisp, resilient and long-lasting image.
While ink is standard in most conventional inkjet home printers, laser printers depend on toner and lasers for their output. Given that they`re based on their own unique technology, you`ll find that they also have their own unique advantages and disadvantages.

Scanning and copying faint image
ANSWER : The scanning is done by light bouncing off of some mirrors. Could be dust on one of the mirrors. Try shining a light down into the scanner unit and look at the mirror that is visible and see if it has dust coating on the side that is light.

Samsung CLP-300 Image Ghosting
ANSWER : Hi there – did you resolve your issue? It exactly mirrors the issue with my Samsung CLP-310. Each print carries across to the subsequent print as a ghost/smeared image and I diagnosis has revealed the transfer belt (ITB) has smeared toner remaining post each print. I was therefore considering replacing the Transfer Belt, but fear it is not the issue as you found. Whatever should be removing the toner from the Transfer Belt post print, is not, and then I get smeared ghosting on subsequent prints of the last print. The only mitigation is to print 5 blank pages post print, then the ghosting/smearing reduces to nearly zero (proving that the toner is being removed partially at least)…. Any help gratefully received.

Laserjet 4250 print quality issue (see image)
ANSWER : It looks like a fuser problem. One way to prove it is with the half-stop test. Put a sheet in the drop down manual feed tray. Send a print job and watch the paper. When the end of it is about to enter the printer, open the lid and take out the toner cartridge. Look at the printed image. If it looks OK, then it is a fuser problem. If not, then it is a toner cartridge issue since it hasn’t gone through the fuser.
