Character Voids
Character voids are white areas within parts of characters that should be solid
black:
• If you are using transparencies, try another type of transparency. Because of the
composition of transparencies, some character voids are normal.
• You may be printing on the wrong surface of the paper. Remove the paper and
turn it around.
• The paper may not meet paper specifications.
Horizontal stripes
If horizontally aligned black streaks or smears appear:
• The imaging unit may be installed improperly. Remove the cartridge and reinsert
it.
• The imaging unit may be defective. Remove the toner cartridge and install a new
one.
• If the problem persists, the machine may require repair.
Curl
If the printed paper is curled or paper does not feed into the machine:
• Turn over the stack of paper in the tray. Also try rotating the paper 180° in the
tray.
White Spots
White spots appears on the page:
• The paper is too rough and a lot of dirt from a paper falls to the inner devices
within the machine, so the transfer roller may be dirty. Clean the inside of your
machine.
• The paper path may need cleaning.
