Letterhead and preprinted forms
Many manufacturers now offer premium paper advertised as laser-compatible or laser-guaranteed.
Some of the rougher surface finishes, such as cockle, laid, or linen, might require the special fuser
modes that are available on some printer models in order to achieve adequate toner adhesion.
Some page-to-page variation is normal when printing with laser printers. This variation
cannot be observed when printing on plain paper. However, this variation is obvious when printing
on preprinted forms because the lines and boxes are already placed on the page.
To avoid problems when using preprinted forms, embossed paper, and letterhead, observe the following
Avoid using low-temperature inks (the kind used with some types of thermography).
Use preprinted forms and letterhead paper that have been printed by offset lithography or
Use forms that have been created with heat-resistant inks that will not melt, vaporize, or release
undesirable emissions when heated to 200° C (392° F) for 0.1 second. Typically, oxidation-set or
oil-based inks meet this requirement.
When the form is preprinted, be careful not to change the moisture content of the paper, and do
not use materials that change the paper's electrical or handling properties. Seal the forms in
moisture-proof wrap to prevent moisture changes during storage.
Avoid processing preprinted forms that have a finish or coating.
Avoid using heavily embossed or raised-letterhead papers.
Avoid papers that have heavily textured surfaces.
Avoid using offset powders or other materials that prevent printed forms from sticking together.
