How does my laser printer work?
Most moving parts in a laser printer are rollers that guide the paper from its tray through the printing process and out of the printer. As the paper travels through the printer, it passes under a rotating cylinder called the photoreceptor, where it picks up toner - which is the laser printer's equivalent of ink. The paper then moves through the fuser assembly, a set of high-temperature rollers that permanently bond the toner to the paper. Most small and midsize laser printers integrate the photoreceptor into the toner cartridge. As the photoreceptor rotates in the cartridge, it moves past the charger corona wire, which places a uniform electrical charge on the photoreceptor's surface. Then a laser beam "writes" an oppositely charged electrical image onto the surface of the photoreceptor. Next, the photoreceptor rotates through the toner reservoir, where toner attaches to the image. Finally, the toner is pulled from the photoreceptor to the paper by an electrical charge placed on the paper by the transfer corona wire.
Condition Your Labels Before Printing
Paper must be kept dry, damp paper does not feed well, and may skew or crease in the paper path. It is recommended that you condition stock while it is still in the original box. Temperature and humidity can have major impact on printing. Even small changes (such as from day to night) can greatly affect feed reliability if the print material is just within the range of acceptability. If at all possible, try to print in a temperature range of 65 degrees to 75 degrees F with relative humidity of 40% to 60%. Lexmark printers are designed to operate in a temperature range of 60 degrees to 90 degrees F with relative humidity of 8 to 80%.
