The printer is certified in the U.S. to conform to the requirements of DHHS 21 CFR Subchapter J for Class I (1) laser products, and elsewhere is certified as a Class I laser product conforming to the requirements of IEC 825.
Class I laser products are not considered to be hazardous. The printer contains internally a Class IIIb (3b) laser that is nominally a 5 milliwatt gallium arsenide laser operating in the wavelength region of 770-795 nanometers. The laser system and printer are designed so there is never any human access to laser radiation above a Class I level during normal operation, user maintenance, or prescribed service condition.

2. Diagnostic Information

Start

CAUTION: Remove power from the printer before you connect or disconnect any cable or electronic board or assembly for personal safety and to prevent damage to the printer. Use the hand grips on the side of the printer. Make sure your fingers are not under the printer when you lift or set the printer down.
Use the service error code, user status message, user error message, symptom table, service checks, and diagnostic aids in this chapter to determine the corrective action necessary to repair a malfunctioning printer.
Service error codes are indicated by a three digit error code. If a service error code is displayed, go to the “Service Error Codes” on page 2-2.
User status messages provide the user with information on the current status of the printer. Ready is displayed on the first line of the display unless Power Saver is invoked, then Power Saver is displayed. If a user status message is displayed, go to the “User Status Messages” on page 2-12.
User error messages are indicated by a two or three digit error code that provides the user with information that explains a problem with a print cartridge, paper jam, option, port, and so on. If a user error message is displayed, go to the “User Error Messages” on page 2-16.
If your machine completes the “Power-On Self Test (POST)” on page 2-24 without an error, and you have a symptom, go to the “Symptom Tables” on page 2-25. Locate your symptom and take the appropriate action.
If a service error code appears while you are working on the machine, go to the “Service Error Codes” on page 2-2 and take the indicated action for that error.
