Disc drawer fails to open
Drawer fails to open or close
when the Open/Close button
is operated.
Cause:
Mechanical blockage, jammed disc, faulty disc mechanism.
Remedy:
Open the disc drawer by hand.
Before you do this, the device must be isolated from the mains supply: this is
accomplished by withdrawing both mains plugs. The disc drawer can now be
extended manually using a 4 mm allen key inserted in the opening in the
back panel (see illustration below): turn the allen key in the direction of the
arrow until the drawer is fully extended.
Cause:
During the closing process the drawer was prevented from closing correctly,
typically by an obstacle, and this has triggered the safety coupling.
Remedy:
The drawer actuating system is fitted with a safety coupling which prevents
damage to the machine if a mechanical blockage should occur. If the safety
coupling is triggered, it can be re-engaged as described in Service Note 115.
