Page 252: Notes On Cartridge
CHAPTER 1 MAINTENANCE AND INSPECTION D. Notes on Cartridge The cartridge is affected by the environment, regardless of whether it is sealed or unsealed and installed in the machine or otherwise. Although the properties of the cartridge change over time independent of how many copies have been made, the degree of care taken for the cartridge affects how long it may remain stable.
Page 253 CHAPTER 1 MAINTENANCE AND INSPECTION 2. Storing and Handling Unsealed Cartridges The photosensitive medium is an organic photoconductor (OPC), which is extremely susceptible to light. Since the cartridge also contains toner, you must be extra careful when storing or handling the cartridge. Make sure the user is aware of this fact and will handle the cartridge with care.
Page 254 CHAPTER 1 MAINTENANCE AND INSPECTION 2) Do not place the cartridge upright or upside down; do not shake it. Figure 1-2D 3) Do not force open the shutter for the photosensitive drum cover found at the bottom of the cartridge; do not touch the surface of the photosensitive drum. If the surface of the photosensitive drum has become soiled, wipe it using a flannel cloth coated with toner.

CHAPTER 2 STANDARDS AND ADJUSTMENTS CHAPTER 2 STANDARDS AND ADJUSTMENTS A. Mechanical 1. Image Leading Edge Non-Image Width (position of white paint on back of glass) The leading edge non-image width must be 2.0 ±1.0 mm when the Test Sheet is copied.
Page 258 If you have replaced the scanning lamp unit, intensity sensor, AE sensor, or control panel PCB, you must adjust the three variable resistors on the control panel PCB (one, if PC400/FC200); you must, however, adjust them in the order of VR604, VR602, and VR603 (from intensity to AE).
Page 259 CHAPTER 2 STANDARDS AND ADJUSTMENTS C (VR604) Control panel PCB C (R614) Figure 2-2B (PC400/FC200) After Replacing the Scanning Lamp Unit, Intensity Sensor, or AE Sensor (Before Adjustment) • If the scanning lamp has blackened, replace it. • Clean the scanning system (lens array, lamp reflector, lamp).
Page 260 CHAPTER 2 STANDARDS AND ADJUSTMENTS 2. Adjusting the AE Mechanism (VR602, VR603) (Before Adjustment) • Obtain a newspaper whose text consists of fine print; do not use a section with photos or large characters. • Make sure you have adjusted light intensity. 1) Switch the copier OFF.

Page 262 CHAPTER 2 STANDARDS AND ADJUSTMENTS 9) Place about five sheets of blank copy paper. 10) Turn VR603 (AE gain adjustment) until the voltage between the anode side of the diode (D606; it) and JP607 (GND) is 1.8 ±0.1 V; see Figure 2-5B. 11) Switch the copier OFF.
