Recommendations
Only use letterhead designed for color laser printers and
photocopiers.
Don’t use very smooth, shiny or glossy paper.
Don’t use heavily embossed headed paper, very rough paper
or paper that has a large grain difference between the two
sides.
• Check www.okiprintingsolutions.com for the latest
information on recommended papers for your printer.
• Paper should be stored flat, away from moisture, direct
sunlight and heat sources.
• The use of heavily laid or textured paper will
seriously affect the life of the image drum and give
poor print quality. Print quality can be improved by
changing the media setting to ‘Ultra Heavy.’ However,
this will reduce the output speed and prevent the use of
the duplex option.
If the Ultra Heavy setting does not give proper toner
fusion, you can try the Label settings.
• Avoid:
– Damp, damaged or curled paper.
– Very smooth, shiny or glossy paper.
– Heavily embossed letterhead paper, very rough paper or
paper that has a large grain difference between the two
sides.
– Paper with perforations, cut-outs or ragged edges.
– Carbon paper, recycled paper, NCR paper,
photosensitive paper, pressure sensitive paper or
thermal transfer paper.
CAUTION
Print media must be able to withstand 446°F
(230°C) for 0.2 second.
