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.
