[Assembly Procedures of Front Housing Block]
[NOTE] Assemble the Front housing block in reverse order of disassembly procedures in
accordance with “Note of assembly”. Carry out the following adjustments and confirmations
after assembled until 0-O100 (section 4-1).
[ADJ./CONF.] Front Housing Block
4-1. [CONF.] Mirror Function Check
[Required equipment] Regulated DC power supply
1) [CONF.] Make sure that the planet gear arm assy should be placed at charge side.
2) [CONF.] Apply DC4~5.5V to 0-S250 (＋: Red, −: Black), and then confirm function and
noise of mirror sheet.
[CAUTION] Do not apply the power to reverse polarity of motor to prevent damage for 0-G100.
1）[CONF.] When applying DC2.5V to the solenoid (No polarity), the switching lever should be
moved to the release direction.
2）While applying the power to the solenoid, and when B103 is rotated both direction normal
and reverse by finger, the planet gear arm should be switched smoothly (Mirror charge side
⇔Winding side).
3）After confirmation is done, set the planet gear arm to mirror charge side.
4）Set the mirror sheet to mirror-down condition. (Set the mirror sheet and sliding plate at
bottom end position and stroke with rotating B103 anticlockwise by using finger.)

4-2. [ADJ./CONF.] 1st and 2nd Mirror Position
[Required equipment] 1st Mirror angle (47.5°) adjusting jig for 27830, Mirror angle adjusting jig
for 27830, Mirror positioning scope
The method of adjustment is the same as other MZ-cameras by turning two B58’s. Adjust the
Y-axis to zero target.
1) Check and adjust the 1st mirror position.
2) Check and adjust the 2nd mirror position.
(For the standard and tolerance, see the next page.)

1）DistributeleadwiresasshowninFig.81.
[NOTE] Do not apply a stress to the lands of 0-O170.
2）[CONF.] Apply DC4V to 0-O170, and then check
position and lighting of 11 points of SI-LED.
3）[ADJ.] Loosen two screws, and then adjust position of
0-O170.
4）After adjustment is done, apply Super-X and Locktite
totheplaceindicatedinFig.82. Fig.80
