1. REPAIR PREPARATIONS

1.1 INITIAL CHECK LIST

(1) Before repairing the camera, measure and record the flange focal distance. After

completing the repair, measure the flange focal distance again. The before and after flange focal distance measurements should be the same. (The AF precision will depend on whether the flange focal distance is the same before and after the repair.)

(2) Check that the AF sensors are clean. To clean, use the adjustment software’s “Clean

AF Sensors” menu.

(3) Check the error codes. Execute any necessary corrective measures. Also, clear the

error codes before returning the camera to the customer.

(4) Check the camera’s serial number and classification number. If repair is necessary,

execute the stipulated repair. Refer to any service manual reports to be issued henceforth.

(5) Record the user’s mode settings (especially the Custom Function settings). After

repairing the camera, set the same mode and Custom Function settings. Executing a

data transfer of all the settings will make this easy. (6) Save the camera’s data. (7) Record the shutter release count. Use this as a reference for replacing the shutter

and lubricating mechanical parts. (8) Be sure to replace all tape holding lead wires, etc. at the same location. Double

check this after replacing a part or removing any tape. (9) Check the operation of all the camera buttons and controls. (10) Inspect the lens contacts and camera-back contacts and clean if necessary. (11) Inspect the inside of the viewfinder and other parts and clean if necessary. (12) After replacing the main board unit or DX flex unit, make sure the short pads are in

the same state as before the replacement.

(13) Be sure to execute all the necessary procedures to keep the camera water-resistant.

1.2 CAUTIONS FOR REMOVING THE COVERS

1) Camera Operation After Bottom Cover Removal

After the bottom cover is removed, the main switch cannot be turned on. To work around this, short-circuit the short pad on the main board. This will enable camera operation. When reattaching the bottom cover, be sure to completely remove the solder from the short pad.

2) Camera Operation After Top Cover Removal

After the top cover is removed, the X-sync contact will be open. In this state, releasing the shutter will result in an error. To work around this, short-circuit the X-sync contact pad on the DX flex. This will enable camera operation. When reattaching the top cover, be sure to completely remove the solder from the short pad.

1.3 ABOUT THE DC/DC FLEX UNIT

1) DC/DC Flex Unit (Interim)

Applicable Units: DC/DC unit classification No. C and before

A small flex is attached.

2) DC/DC flex unit (permanent)

Applicable Units: DC/DC unit classification No. D onward

The small flex and lead wire will be eliminated.
