If the DF harness is not routed properly, the rear cover may press the DF harness against the interface board when the rear cover is closed. This might cause the interface board connector to come off from the main board connector, which would clear RAM memory. To ensure the connection, the rubber cushion has been adhered on the main board as shown in the illustration.
NOTE: The DF harness must be routed correctly. Please refer to RTB No. 002 for the details.

To facilitate servicing, the spectral characteristics of the filter on the dust proof glass has been changed. The light intensity passing through the filter has been increased. With the new filter, the adjustment value of the SP mode #48 (exposure lamp intensity adjustment) at the factory has been decreased. This increases the adjustment rarge of SP mode #48 in the field.

DETAILS OF MODIFICATION
The PG gap is preset with special tools at the factory and the screws securing the drum support plat e and front drum side plate are paint locked. Basically, those parts should not be removed except when they are being replaced. To make part replacement easier, the service parts have been changed as follows:
The drum support plate assembly, consisting of the drum side plate and the front drum side plate, ha s been registered as a service part instead of the component parts. (For the details, please refer to RTB #4.) The drum support plate an d the front drum side plate are no longer abailable as service parts.
NOTE: • Do not loosen or remove the screws [A] which are paint locked.
• Two screw holes [B] have been added to the drum side plate so that the drum support plate assembly can be replaced.
