The office printer and copier machine have been staple equipment for most commercial and industrial enterprises anywhere in Singapore as much as personal computers. Although often riddled with various problems, the laser printer, copier, colour printer, and graphic art printer have come a long way in terms of functionality, durability, and functions.
Knowing how the office printer and the copier machine work will allow you to pick the most suitable type and model for your office needs.
How the Copier Works
Like printers, a copier machine uses the same mechanics in transferring an image or text on a blank page regardless of the type or extra features included. First, the document that needs to be copied is placed upside-down on the glass so that the scanner can scan the paper. The scanner works by reflecting light off white or blank surfaces to form a shadow on the photoconductor, which is coated in selenium.
This photoconductor rotates and touches the ink drum so that the photoconductor is coated with the toner. Once the toner is charged, it will stick to the shadow on the photoconductor. A blank paper is loaded and is moved in another conveyor belt before being electrically charged. The charged toner becomes attracted to the paper resulting in a recreation of the image or text. The paper finally passes between two hot rollers to fuse the toner.
Types of Copiers
1. Mono Copier – Also called the black and white copier machine, the mono copier uses only one type of toner. Modern mono photocopiers recommended for office use can print up to 150 ppm (pages per minute) and will save you a lot of money if you do not need to print color copies.
2. Colour Copier – This type of copier machine can also produce mono copies, but you can also print colour copies because it uses four tones, such as cyan, magenta, yellow, and black. Like the colour printer, they can print different colors within the CMYK spectrum.
3. Desktop Copier – This is recommended only for individual use or for small offices in Singapore that have very low print volume. Some Singapore oki printing machine models are multifunctional, but you can only reproduce copies for limited sizes of paper because most desktop copiers can only print up to the A4 size.
4. Digital Copier – Some modern copier machines have larger capacities than the old models. They are also classified as multifunctional printers because they can also print, scan, and fax.
5. A3 Copier – Some offices always forget to consider the size of paper used for printing. Although most copiers and printers can print of standard letter size, other offices might want to consider getting an A3 copier for posters and other larger printing needs.
How the Printer Works
Before you buy a printer in Singapore, make sure that you know which type is suitable for your office or personal needs. Any type of office printer, however, follows the same principles by converting text and digital images into a physical copy. These texts and images are recreated on the paper using very tiny dots. How these dots are transferred to a blank paper or material is what separates the different types of printers.
Types of Printers
1. Laser Printer
Sometimes called the LED printer, the laser printer works by transferring the image or text on a paper using dots so that the replica appears as one solid image. The laser printer uses a toner to make up the dots, which are fine power or solid in nature, unlike the liquid dots used in an inkjet printer.
The process of transferring the image or text , therefore is more complicated because the drum in the printer must be charged before the laser is shone on it to determine the outline of the image to be printed. This attracts the toner to the areas on the drum that are charged so that the rollers transfer the powder to the drum.
If the surface is charged, the toner will be repelled and consequently, the areas that are not charged will attract the toner and stick to the drum. When the paper makes contact with the drum, the image is transferred. Most offices that want to buy printer in Singapore choose the laser printer because the overall cost after the initial purchase is cheaper.
2. Dot Matrix
The dot matrix is the perfect office printer for offices that do not need to print or copy large volumes of paperwork daily. The image and text are recreated on a blank page through the striking of the print head on an ink-soaked cloth. It’s a lot slower than inkjet and laser printers, has low resolution and is noisy, but it is a low-maintenance and cheap alternative.
3. Inkjet Printer
Most of the graphic art printer you see in the market are inkjet printers because they produce better images than laser printers. An inkjet printer uses a print head with tiny holes to transfer the ink on the paper. The transfer of the ink happens when the tiny holes are heated and a drop is pushed out. This process is what creates a solid, beautiful image in most colour printer used for posters, photos, and other materials that need clear images.
4. Solid Ink
This type of printer can be found in most copier machine and combines the benefits of both inkjet and laser printers. When you buy printer in Singapore, make sure to ask what type of ink and printing method is used to create copies. The solid ink printer uses wax that is melted and sprayed on a drum and transferred to a print head. The intended image is recreated on the roller and is then transferred on a blank page. This could be the perfect graphic art printer for offices in Singapore that need to print posters, cards, invitations, pamphlets, and other materials that need colorful and vibrant prints.
