Isolate a Paper Type
When paper jams and other problems occur frequently, it is often because the customer is
using a special paper. Customers must only use paper that conforms to all HP
specifications, and should always test paper before purchasing large quantities. Paper
should be tested before storage to verify quality printing results. Then, if problems arise in
the future, storage or handling conditions will be the most likely cause. Some types of media
that may cause problems are:
• Pre-printed forms and special letterhead
• Embossed paper
• Perforated paper
• Adhesive labels
• Envelopes
• Transparencies
• Chemically treated paper
• Synthetic paper
• Coated paper
• Other special media
Pre-printed Forms and Special Letterhead
Many pre-printed forms and special letterhead papers perform well in HP LaserJet printers.
However, these papers undergo processes that alter their original characteristics and care
must be taken to ensure they conform to HP specifications. All special papers should be
wrapped in moisture-proof wrapping when purchased from the paper converter or printing
house.
Forms and letterhead must be printed with inks that conform to the following specifications:
• Only use ink that is heat-resistant, and will not melt, scorch, or release hazardous
emissions when subjected to 200 degrees C (392 degrees F) for 0.1 second.
NOTE: Do not use low-temperature inks (the kind used with thermography).
• Inks must have resistance to silicon oils, and must not be affected by resin components
in toner.
• Inks must not be flammable.
• Inks must not “offset” (transfer from the printed paper onto the printer, contaminating
internal printer components). The principle cause of offset is ink which is not fully dried
or which cannot withstand the printer fusing temperature.
