4-3. Mechanism checks and adjustments
The description given below relates to the general field services, but does not relate to the adjustment and replacement
that require high level equipments, jigs, and technical skills.
In order to maintain the initial characteristics of the machine, it is necessary to execute the maintenance and check and
to prevent damage to tapes and other parts. For adjustments which need jigs, be sure to use the jigs.
Notes and cautions
(1) For mechanism checks and adjustments, be sure to use the AC adapter as the power supply.
(2) For running the tape, be sure to install the cassette control ass’y in advance. (If the cassette control ass’y is to be
removed subsequently after its installation.)
4-3-1. Checking the reel disk height
(1) Remove the cassette control ass’y.
(2) Taking due care not to let the master plane touch the tape running areas such as the drum and the guide rollers,
position the master plane so that the two guides (A and B in the figure 1) are set in the holes of master plane, then
properly set it in the mechanism.
(3) Using the slide callipers or the like, check that the distance from the upper surface of master plane to the reel support
surface of the S/Tu reel disk is within the specified range.
Note:
When measuring, do not apply excessive force to the reel support surface of reel disk.
(4) If the measurement is not within the specified range, replace the reel disk ass’y.
(5) Check the items (2) to (4) above in the following two modes.
a) Standby mode
b) Playback (recording) mode
