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.
Notes:
Make sure that the jumping wires are no longer shorted.
12) Switch the copier ON once again.
13) Set the density correction switch (SW606) to the center (of the three settings).
14) Make sure that the AE indicator is ON.
15) Set the newspaper used in step 4) on the copyboard once again; this time, move the
newspaper to a different area.
16) Make a copy, and make sure that it is not foggy and has adequate text density.
• If foggy,
Turn VR602 clockwise slightly.
• If text density is low,
Turn VR602 counterclockwise slightly.
17) Repeat steps 15) and 16) until the density is optimum.
