Problem
Excessive paper curl – Paper curl may be a result of:
– The mass of toner coverage on the copy - the greater the
toner mass, the greater the paper curl.
– The paper weight
– The humidity conditions at the copier/printer.
– You can sometimes minimize curl problems by flipping the paper
over in the tray and making the copies again. If excessive curl is
still present, use a heavier paper.
– Ensure the paper matches the type defined for the Paper Tray.
– Attempt to minimize the amount of toner on the copy paper by
selecting the Photo feature as the Original Type and /or the
lighter and/or less contrast image quality options.
– When the Finisher Transport is present the Output Catch Tray
can hold up to 250 sheets of 24 lb. (90 gsm) paper. Empty the
catch tray when output approaches this limit to ensure continuous
production.
– The Center Output Tray has a capacity of 400 sheets of 24 lb. (90
gsm) paper. Remove the output when it approached this limit to
ensure continuous production.
– Copying high density background areas or documents with
alternating high and low density areas results in more curl.
Attempt to reduce the amount of curl by adjusting the copy quality
controls to reduce the amount of toner on the copies.
– Place the copier/printer and paper in a room with air conditioning
and low humidity to minimize the moisture in the environment.
– Attempt to copy on thicker paper or on paper stock that is less
sensitive to moisture.
