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: NEVER manually actuate or disable the top cover interlock switch and the printhead shutter actuator at the same time. To perform some of the service checks and tests, such as

troubleshooting paper feed problems, you need to actuate the top cover interlock switch with the covers opened or removed and power applied to the machine. It is important for personal safety that you DO NOT, FOR ANY REASON, disable the printhead shutter actuator when power is on.

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 service error code, user error message, symptom table, service checks, and diagnostic aids in this chapter to determine the corrective action necessary to repair a malfunctioning printer.

The lights on the operator panel can indicate either a user error message or service error message. When a service error occurs, the printer stops printing and all operator panel LEDs blink in a continuous pattern, indicating a service error, until the printer is powered off. If all operator panel LEDs are blinking, go to the

Error Codes” on page 2-2

When a user error message occurs, one or two operator panel LEDs are on solid or blinking. Go to the

page 2-6
