Manual for AX-1
Uploaded: Aug. 9, 2025, 11:48 p.m.
This manual details the reassembly, repair, and adjustment of the Fujica AX-1 camera, focusing on shutter blind traveling velocity and shutter speed. Key steps include installing attracted pieces, ensuring proper engagement of the 2nd blind hook, and checking magnet attracting forces. The process involves applying DC voltage to magnets, setting release levers, and carefully installing components with adhesive. Adjustments for shutter speed involve using a time generator, connecting it to the M-circuit board, and applying specific signals to calibrate traveling velocities. The manual also covers troubleshooting common issues like shutter blinds not opening or fluctuating speeds, identifying causes such as broken magnet coils or insufficient attracting/holding forces, and providing corrective actions like cleaning or adjusting components.
Troubleshooting and error codes
| Problem | Cause | Corrective Action |
|---|---|---|
| Approximately 15 msec. are counted at 1/1000 sec. | Coil of α magnet (for 1st blind) is broken or attracting force of the α magnet is insufficient. | - |
| Shutter blind does not open. | Coil of β magnet (for 2nd blind) is broken or attracting force of the β magnet is insufficient. Insufficient claw engagement. | To recover attracting force of the magnet, clean the attracted piece. Set shutter speed to "B" to move the iron core to the attracting position, and with the shutter speed "B" maintained, retighten the set screw. |
| Both the 1st and 2nd blinds do not run. | γ magnet does not operate. Improper position of the stop lever (5-159) Relase lever (5-163) does not operate. | - |
| 1/1000 sec. shutter speed fluctuates. | Insufficient attracting forces of α and β magnets. Insuffucuent holding forces of α and β magnets. Attracted piece is not fixed securely. | - |
| The 1st blind opens when wound up rapidly. | Insufficient engagement of 1st blind hook and improper height. Release lever (5-163) of the magnet moves when winding up the shutter blind. | - |
