CHAPTER 2 ERROR INDICATIONS & TROUBLESHOOTING 1. INTRODUCTION Troubleshooting is a collection of solution procedures that service personnel should follow if an error or malfunction occurs in the machine. It is difficult to determine troubleshooting procedures for all possible problems that may occur in the future. Therefore, this chapter describes typical problems and recovery procedures for these. These will help service personnel identify and repair other similar defective sections. 1.
1.2 Checks before Commencing Troubleshooting Check the following items before commencing repairs on the machine. Operating environment (1) The machine is placed on a flat, stable surface. (2) The machine is used in a clean environment where the temperature is 10°C (50°F) to 32.5°C (90.5°F), and the relative humidity is maintained between 20% and 80%. (3) The machine is not exposed to direct sunlight, excessive heat, moisture, or dust. (4) Hold the machine level while moving it.
Others (1) Condensation When the machine is moved to a warm room from a cold location, condensation may occur inside the machine, causing various problems as listed below. • Condensation on the surface of optical devices such as the lens, reflecting mirror and protection glass 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 print density.
