Displays in normal operation
Explanation / Measures
Carefully clean the send and
receive diode between the stacker
wheels with a brush. Place CMD-V4
back into cash-out position. If the
status display continues to show
error code '90' after powering up
(reset), remove the stacker unit
and, from below, clean the surfaces
of the prism between the stacker
wheels. Put the CMD-V4 back in its
dispensing position. If the status
display continues to show error
code '90' after powering up (reset),
the stacker has to be replaced.
Use the 'DYK' self-test program
(check status of
photosensors/photosensor
amplifiers) to check the level of dirt
on all photosensors in KDIAG.
Photosensors with status '3' or
higher must be cleaned. The
improvement in status can be
checked after reset.
Note:
When this error has occurred for
the first time, the CMD-V4 will
continue to function until operation
shuts down automatically when the
level of dirt increases.
