Troubleshooting
D-22 Using Paper
Is the Printer Experiencing Misfeeds?
The following are some possible causes in misfeeds.
• Paper may be too stiff. Check basis weight and measure caliper.
• Paper may be too smooth or too rough. Check the finish.
• Paper may be too heavy or too light. Check the basis weight.
• The customer may be attempting to print embossed paper, pre-printed forms, or perforated
paper which does not meet HP specifications. (See the following section, "Isolate a Paper
Type", for details about the difficulties of embossed paper.)
• Paper may be loaded incorrectly. Turn over the sheets in the paper tray to determine if in-
ream curl is the cause of misfeeds.
• Customer may be fanning paper before loading it into the paper tray.
• The printer or paper storage environment may be too humid or too dry. (As a result, paper
may be too moist or too dry). Determine if this is the case and advise the customer.
Isolate Paper Brand
If the printer jams with only one brand of paper:
• If the paper ream being used appears to be old, open a fresh ream of the same paper and
load it properly into the printer. If the problem is remedied, investigate storage and
handling conditions.
• Do not purchase more paper than you can use in a short time (3 months). Paper stored for
longer periods may experience heat and moisture extremes which can damage it. Planning
helps prevent damage to your paper supply.
• If the problem persists, try switching paper brands.
Isolate a Paper Type
When paper jams and other problems occur frequently, it is often because special paper is
causing the difficulty. Use only paper that conforms to all HP specifications, and always test
paper before purchasing large quantities. If future problems occur, the cause may be easily
isolated to storage or handling conditions.
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
