Handling and using special
paper
2
The machine is designed to work well with
most types of xerographic and bond paper.
However, some paper variables may have an
effect on print quality or handling reliability.
Always test samples of paper before
purchasing to ensure desirable performance.
Store paper in its original packaging and keep
it sealed. Keep the paper flat and away from
moisture, direct sunlight and heat.
Some important guidelines when selecting
paper are:
„ Do not use inkjet paper because it may
cause a paper jam or damage your
machine.
„ Preprinted paper must use ink that can
withstand the temperature of the
machine's fusing process (200 degrees
centigrade).
„ If you use bond paper, paper having a
rough surface or paper that is wrinkled or
creased, the paper may exhibit degraded
performance.
