Page 27: Chapter 2 Error Indications & Troubleshooting
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.
Page 28: Checks Before Commencing Troubleshooting
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°C (89.6°F), and the relative humidity is maintained between 20% and 80%.
Page 29  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.
