Paper Handling Advice


  • Paper is hygroscopic.
  • It can absorb moisture from and release moisture to its surroundings.
  • This happens predominately at the sheet edges.
  • This inconsistent moisture loss will cause a sheet to distort.
  • Exposed to a dry atmosphere will cause edges to shrink resulting in a saucer shaped sheet and the effect known as tight edges. Exposed to a damp atmosphere the sheets will expand whilst the middle remains in its original shape causing baggy edges.


  • The key to successful running in laser and inkjet printers is to ensure that all paper remains protected from the atmosphere to reduce the gain or loss of moisture.
  • Always leave paper in its original waterproof wrapping until use.
  • Whenever possible allow the unopened paper to acclimatise to its surrounding temperature before opening and using.
  • The time taken for paper to acclimatise to its surroundings varies according to the weight of paper involved and the temperature gradient. It can take as long as two days.
  • Paper should always be knocked up into square stacks and covered before use.
  • When not using, re-wrap or cover paper to assist moisture protection.


  • Do not store paper near sources of heat or near open doors and windows even when wrapped.
  • Paper should wherever possible be protected from drastic variations in temperature.
  • Paper should always be stored flat and clear of the floor and therefore clear of damage or damp.
  • Should reams split open they should be re-wrapped or the packaging repaired and re-sealed.
  • Any distortion of the paper by not keeping it flat for example will cause irreversible damage.
  • Allowing reams to overhang or be stacked indiscriminately can be a potential source of damage.
  • It is recommended that only paper to be immediately used is removed from its wrapper and any opened paper should not be left overnight in copier feeder tray.
