If you are unable to find the answer you need in the printed documentation supplied with your product or on
the web, you can contact one of the HP support services listed in the following pages. If a support service
number is not listed for your country, contact your nearest authorized HP dealer for help.
Before calling customer support
1 Make sure that
• Your unit is plugged in and turned on.
• The correct print cartridge is installed properly.
• The recommended paper is loaded in the input tray.
2 Reset your unit by unplugging it and plugging it in again.
3 If you need to speak to an HP Customer Support Representative:
• Have your serial number ready.
• Print a Self-Test Report.
• Be prepared to discuss your problem in detail.
4 Be near your unit when you call.
Prepare your unit for shipment
If you are requested to send in your unit for service, do the following:
• Remove the print cartridge and place it in an airtight bag so it will not dry out. Do not send the print cartridge with the unit unless
asked to do so.
• If you do not have the original packing material, you can request a replacement package set from HP Customer Support. Shipping
damage caused by improper packaging is not covered under the warranty.
• Include these items in the box:
• A brief description of the symptoms (sample prints are helpful).
• A copy of your sales slip or proof of purchase (to establish the warranty period)
• Your name, address, and telephone number where you can be reached during the day.
* U.S. phone support is available in both English and Spanish 24 hours a day, 7 days a week (days and hours of support
may change without notice).
