CHAPTER 2 ERROR INDICATION AND TROUBLESHOOTING
CHAPTER 2 ERROR INDICATION AND TROUBLESHOOTING This chapter details error messages and codes which the incorporated self-diagnostic function of the machine will display if any error or malfunction occurs. If any error message appears, refer to this chapter to find which parts should be checked or replaced. The latter half of this chapter provides sample problems which could occur in the main sections of the machine and related troubleshooting procedures. CONTENTS 1.

1. INTRODUCTION Troubleshooting is the countermeasure procedures that the service personnel should follow if an error or malfunction occurs with the machine. It is impossible to anticipate all of the possible troubles which may occur in future and determine the troubleshooting procedures, so this chapter covers some sample troubles. However, those samples will help the service personnel pinpoint and repair other defective elements. 1.
1.2 Initial Check Check the following items before attempting to repair the machine. ■ Operating environment (1) Put your machine on a flat, stable surface such as a desk that is free of vibration and shocks. (2) Use the machine in a well-ventilated room; use the machine within the following ranges of temperature and humidity: temperature between 10 °C and 32.5 °C (50 °F to 90.5 °F), and the relative humidity is maintained between 20 % and 80 %.
■ Others (1) Condensation When the machine is moved from a cold place into a warm room, condensation may occur inside the machine, causing various problems as listed below. • Condensation on the surface of optical devices such as the laser scanner windows, lens, reflecting mirror, and protection glass, etc, may cause light print image. • If the exposure drum is cold, the electrical resistance of the photosensitive layer is increased, making it impossible to obtain the correct contrast when printing.

2.6 Life of Toner Cartridge and Drum Unit This product detects the remaining toner only by the dot count and the number of rotations of the develop roller. The function to detect by the light sensor is not installed. As this machine is not equipped with a toner sensor as conventional models are, it manages the level of remaining toner by dot count during printing and the number of rotations of the develop roller.

The life of the drum unit is judged the value of either large one of “Drum Counter” of “Number of rotations of exposure drum”. The drum counter is based on the number of pages actually printed for every drum unit. Whenever it replace for a new drum unit, it is necessary to reset this number of sheets.
3. ERROR CODES This machine includes a self-diagnosis function. If the machine does not work normally it judges that an error has occurred, and indicates the corresponding error message on the LCD, which in turn helps the service men to quickly find out the problem. 3.1 Error Codes The errors with a mesh background in the table below do not occur in the normal operation.
