Role of Laser Printer for Barcode Production

Laser printer is a printer that utilizes laser technology to print barcode images on the paper. Laser printers are often used in various industries including corporate, professional, colleges, school and other environments that require print barcode labels, tags and sticker for labeling in large quantities. You can easily print barcodes and other product related information on any type of primary or secondary packaging with laser printers.

What can you print

• Print product barcodes in linear and 2D codes seamlessly on any type of product using barcode maker software
• Print labels for primary packaging like glass, plastic, aluminum and paper
• Print barcode for secondary packaging like batch boxes, bottle pouches, carton boxes
• Print high resolution codes for irregular or curved surfaces

Laser printer parts and functioning :-

Receiving Data: Firstly laser printer needs to receive the data in barcode text or picture format from computer system, this process is control by printer controller that is the laser printer’s main on board computer. Once the data is received and buffered the printing process starts. In the printing process, data receiving speed and printing speed are different, therefore laser printer stores received data before printing.

Charging drum: Toner cartridge consists of aluminum cylinder coated with photosensitive material, fresh toner tank and waste toner collection tank. Once the data is received, drum is charged with high negative voltage through the charge corona wire placed at the top of the drum in toner cartridge.

Exposing drum: Received data is fed to the laser diodes or LED’s to illuminate. These light rays which is same as the received character, is written on the charged drum, and there by negative charge is neutralized in the drum surface. When the drum rotates and come closer to the toner container, exposed areas attracts the negatively charges toner particles thereby forming visible image in the drum surface.

Paper feed: Once the drum is ready with printable data, Paper pick-up roller assembly works to pick up barcode paper. Then paper is fed in between highly charged transfer roller and drum unit. Transfer roller charge pulls the toner particle in the drum unit which sticks to the paper there by image is transferred to the paper.

Fusing: Since the barcode image or data in the paper is erasable, paper is fed in to fusing unit. Fusing or fuser unit has two rollers, Heat roller attains maximum temperature using halogen lamp and another roller applies pressure when the paper is fed in between them. Due to high temperature in the heat roller toner and glue particles in the paper melts and sticks to the paper and the image becomes permanent.

Discharge: To print the next received data, drum must be cleaned to remove any traces of previous pages. Rubber blade wipes the excess toner from the drum, and then discharge lamp is used to expose and clean the drum by neutralizing residual electrical charges on it. A grounded discharge material touches the paper to remove electro static charges when paper exit from printer.
