Paper and moisture

Managing your paper supply

Paper and moisture

Paper fibers expand or contract with changes in humidity. Changes in moisture content can cause paper to deform, change dimensions, or change in stiffness.

Problems caused by moisture

Excess moisture in paper can cause:

•Jams, deletions, and/or wrinkles due to sheets with wavy edges

•Jams due to paper curl

•Misfeeds or multi-sheet feeds, especially with coated stocks

•Mottle (spotty or uneven images)

•Jams due to sheets becoming less rigid and bunching up in the paper path

•Deletions and/or lighter images because excessively high or low resistivity makes paper less able to attract dry ink

•Water marks on sheets due to condensation

•Image quality problems and machine contamination due to coating rubbing off of paper

Low moisture in paper can cause:

•Jams due to static electricity

•Misfeeds or multi-sheet feeds

•Deletions and/or wrinkles due to sheets with tight edges (edges shrink and curl slightly)

•Poor dry ink transfer (small deletions and uneven density)

•Folds and jams due to paper being too stiff

A change in paper dimension due to moisture can cause misregistration, especially with duplex printing.

Controlling moisture in paper

Follow these guidelines to prevent moisture-related problems:

•Store paper on pallets, on shelves, or in cabinets. Cartons can absorb extra moisture if placed on the floor.

•Store paper in a climate controlled room, if possible. Most air conditioning systems provide a good mix of temperature and humidity. Paper will perform best if the storage area is between 68° and 76°F (20° and 24°C) with 35 to 55% relative humidity.
