Laser Interlock Mechanism The position of the switch (S1702) for detecting loading completion is detected by t

4、he system microprocessor, and the design prevents laser diode oscillation when the switch is not in LPS1 terminal side (when the mechanism is not clamped and LPS1 signal is high level.) Thus, the interlock will no longer function if the switch is deliberately set to LPS1 terminal side. ( if LPS1 sig

5、nal is low level ). In the Service mode the interlock mechanism will not function. Laser diode oscillation will continue, if pin 41 of TC94A15FG (IC201) on the MAIN Assy is connected to GND, or else the terminals of Q201 are shorted to each other (fault condition).2.

28、UT POWER SUPPLY MONITORING For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering. Co

29、mpared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although the temperature depends on the heat capacity of the PC board on

30、 which reworking is required and the weight of the tip of the soldering iron.Do NOT use a soldering iron whose tip temperature cannot be controlled.Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy

31、 to harden).The following lead-free solders are available as service parts: Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.This unit always monitors for power failure and will shut itself off immediately after an error is detected. If an error is genera

32、ted, the STANDBY LED will flash after the unit shuts itself off. After the unit shuts itself off because of an error, unplug the AC power cord and wait 1 minute before turning the unit ON by pressing the STANDBY/ON key.Repair the unit, according to “5.5 ABOUT POWER SUPPLY MONITORING.”7CDJ-8505678567
