Which is better Multi-purpose copy paper or Xerographic Paper?

Answer 1

To ensure high quality and performance from xerographic printers, the paper should be optimized for printing in digital systems and must meet the following requirements:

• Paper must be as free as possible of the paper dust that can result from cutting and wrapping operations. If not strictly controlled, contamination from paper dust eventually causes difficulties, downtime, and a need for service. Buildup of paper dust and loose fibers is one of the leading causes of service calls and correspondingly lost productivity.

• The paper path through the printer demands that the paper bends in order to pass around drums, feed rollers, and other portions of the transport mechanism. Paper with excessive curl, due to high moisture content or other causes, is likely to jam. Paper with excessive curl is another leading cause of service calls.

• Some xerographic printing systems use both friction-feed and vacuum-feed mechanisms to feed the paper from the various trays. Paper must have the correct frictional properties or misdeeds may result. Additionally, the sheet must have adequate porosity to ensure reliable performance in the vacuum mechanism.

• During the image-transfer process, the paper is subjected to electrostatic charges. If the paper lacks the proper electrical characteristics, dry ink may not transfer properly or completely, causing image quality defects or other failures.

• The dry ink is fused to the paper by a combination of heat and pressure. Paper with an excessively rough surface can cause fusing failures, preprinted forms with incorrect inks can cause smearing or offsetting of the preprinted portions of the image, and paper that contains traces of contaminants can cause spotting of the photoreceptor (this is where the image is transferred) and poor imaging of subsequent prints. Suitable smoothness levels are also required to prevent image graininess and achieve acceptable toner adhesion results.

HELPFUL FACTS ABOUT PAPER

• The high temperature used for fusing in most printers, combined with the friction of paper being moved at high speeds through the system can generate static electricity. This tendency is exacerbated by paper whose moisture content is too low. Static produces problems with output operations such as stacking and sorting, as well as difficulties in a wide variety of post-processing applications.
