5.1.1 Special Considerations When Printing on Paper
Because of the way laser printers print and bond toner to the paper, you
must observe some special requirements with certain types of papers.
• Do not use preprinted papers that do not meet the specifications for
heat tolerance. The ink from some preprinted papers, such as those
with a company letterhead, can cause smearing and in some extreme
cases could damage the printer.
• Do not use colored papers in which the color is applied as a coating to
the surface.
• Do not use thermal papers.
• Prepunched paper is not recommended.
• Do not use carbon papers.
