UBI EasyCoder 501 – Technical Manual
SENSOR KIT
As an option, the EasyCoder 501 E and EasyCoder 501 SA can be
fitted with two sensors, which detect the rotation of the paper supply
spool and the ribbon unwind shaft and update two counters, one for
each sensor. By means of custom-made application programs, the
counters can be read and used to indicate paper-low and ribbon-low
conditions (as opposed to out-of-paper-out and out-of-ribbon con-
ditions, which are supported by the standard error handling). See
SYSVAR
in UBI Fingerprint manuals or in the UBI Direct Protocol
Programmer's Guide.
The sensors require no regular cleaning. However, should any
malfunction be detected, you may try to blow the sensors clean from
dust or paper residue before calling for service.
The sensitivity of the sensors cannot be adjusted.
