Selecting the right paper
Printer printing is a process involving LED light, electrostatic discharge, toner,
and heat. In addition, as the paper passes through the printer it undergoes
considerable sliding, bending, and twisting motions. A high-quality printing paper
matching the requirements withstands all these stresses, enabling the duplexer and
the printer to turn out clean, crisp printed copy consistently.
Remember that all paper is not the same. Some of the factors to consider when
selecting paper for duplex printing are as follows:
Condition of the paper
Avoid using paper that is bent at the edges, curled, dirty, torn, or contaminated
with lint, clay, or paper shreds.
Use of paper in these conditions can lead to illegible printing, misfeeding, and
paper jams, and can shorten the life of the duplexer and the printer. In particular,
avoid using paper with a surface coating or other surface treatment. The paper
should have as smooth and even a surface as possible.
