7. The rollers above the tray might be contaminated. Clean the rollers with a lint-free cloth dampened with
warm water. Use distilled water, if it is available.
CAUTION: Do not spray water directly onto the printer. Instead, spray water on the cloth or dab the cloth
in water and wring it out before cleaning the rollers.
The following image shows examples of the roller location for various printers.

The printer picks up multiple sheets of paper
If the printer picks up multiple sheets of paper from the tray, try these solutions:
1. Remove the stack of paper from the tray and flex it, rotate it 180 degrees, and flip it over. Do not fan the
paper. Return the stack of paper to the tray.
NOTE: Fanning the paper introduces static electricity. Instead of fanning the paper, flex the stack by
holding it at each end and bringing the ends up to form a U shape. Then, rotate the ends down to reverse
the U shape. Next, hold each side of the stack of paper and repeat this process. This process releases
individual sheets without introducing static electricity. Straighten the paper stack against a table before
returning it to the tray.
