Moisture Content
The amount of moisture in the paper affects both print quality and the ability of the printer to feed the
paper properly. Leave the paper in its original packaging until you are ready to use it. This limits the
exposure of the paper to moisture changes that can degrade its performance.
Grain Direction
Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running
the length of the paper, or grain short, running the width of the paper. For 60 to 135 g/m2 (16 to 36 lb.
bond) paper, grain long fibers are recommended. For papers heavier than 135 g/m2 (36 lb. bond),
grain short is preferred.
Fiber Content
Most high-quality xerographic paper is made from 100% chemically pulped wood. Paper containing
fibers such as cotton possess characteristics that can result in degraded paper handling.
Recommended Paper
To ensure the best print quality and feed reliability, use 75 g/m2 (20 lb.) xerographic paper. Business
papers designed for general business use also provide acceptable print quality.
Always print several samples before buying large quantities of any type of print media. When choosing
any print media, you should consider the weight, fiber content, and color.
The laser printing process heats paper to high temperatures of 225°C (437°F) for Magnetic Ink
Character Recognition (MICR) applications, and 205°C (401°F) for non-MICR applications. Only use
paper able to withstand these temperatures without discoloring, bleeding, or releasing hazardous
emissions. Check with the manufacturer or vendor to determine whether the paper you have chosen is
acceptable for laser printers.
Unacceptable Paper
The following paper types are not recommended for use with the printer:
1) Chemically treated papers used to make copies without carbon paper, also known as carbonless
papers, carbonless copy paper (CCP), or no carbon required (NCR) paper
2) Preprinted papers with chemicals that may contaminate the printer
3) Preprinted papers that can be affected by the temperature in the printer fuser
4) Preprinted papers that require a registration (the precise print location on the page) greater than
±0.09 in., such as optical character recognition (OCR) forms
In some cases, you can adjust registration with your software program to successfully print on
these forms.
5) Coated papers (erasable bond), synthetic papers, thermal papers
6) Rough-edged, rough or heavily textured surface papers or curled papers
7) Recycled papers containing more than 25% post-consumer waste that do not meet DIN 19 309
8) Multiple-part forms or documents
9) Label paper with Cut
Selecting Paper
Proper paper selection helps prevent jams and ensures trouble-free printing.
To help avoid jams or poor print quality:
1. Always use new, undamaged paper.
2. Before loading the paper, identify the recommended print side of the paper. This information is
usually indicated on the paper package.
3. Do not use paper that you have cut or trimmed yourself.
4. Do not mix print media sizes, weights, or types in the same source. This may result in a paper jam.
5. Do not remove trays while a job is printing or Printing is displayed on the operator panel.
