Power requirements are based on the region where the printer is sold. Do not convert operating voltages. This can damage the printer and void the product warranty.

The following environmental specifications must be maintained to ensure the correct operation of the printer. Consider the following points before installing the printer:

lPlace the printer on a sturdy, level surface.

lAllow adequate space around the printer for unimpeded operation.

lInstall the printer in a well-ventilated room.

lPrevent exposure to direct sunlight or chemicals, including ammonia-based cleaning solutions.

lEnsure that an adequate power supply is used.

lInstall the printer in environment where no abrupt temperature or humidity changes occur.

Service approach

Repair of the printer normally begins with a three-step process:

lIsolate the problem to the major system (the host computer, the network and/or server, or the printer system).

lDetermine whether the problem is located in one of the paper-handling devices or in the printer engine.

lTroubleshoot the problem using the procedures in chapter 7.

Once a faulty part is located, repair is usually accomplished by assembly level replacement of field replaceable units (FRUs). Some mechanical assemblies may be repaired at the subassembly level. Replacement of components on the printed circuit assemblies is not supported by Hewlett-Packard.

Customer support and product repair assistance for other customers

HP provides a free telephone support service during the warranty period. By calling the appropriate telephone number for your country or region, you will be connected to a responsive team waiting to help you. If you require support after your warranty has expired, you can receive support for a fee through the same telephone number. The fee is charged on a per-incident basis. When calling HP, have the following information ready: product name and serial number, date of purchase, and description of the problem.
