Low diameter
In the Setup Mode (see Appendix A), it is possible to specify the diameter
(in millimeters) of the ribbon supply roll, when a ribbon low condition
should occur. By default, this parameter is set to 0, which disables the
function. To enable it, enter the desired value.
The status of the ribbon sensor can be polled by reading SYSVAR(26) in a
Fingerprint application program. SYSVAR(26) returns 0 if the diameter of
the ribbon supply roll is greater and 1 if it is less than the value entered in
the Setup Mode. A trap is also sent that can be detected when the printer is
connected to a network via an EasyLAN interface.
Note that a full forward rotation of the supply bobbin must have been
completed. If not, 0 will be returned.
Note: When the ribbon low function is enabled, error condition 1083
"Ribbon low" is reported every tenth time SYSVAR(26) = 1 is detected in
connection with a PRINTFEED.
Sensitivity
• Enter the Setup Mode and follow the path:
Media/Paper Type/Transfer/Ribbon Sensor
• In the Ribbon Sensor menu, press <Enter> to perform a Testfeed.
• The printer will feed out a few labels and feed the ribbon accordingly.
• While the ribbon mechanism is operating, the ribbon sensor is
autoadjusted and the resulting adjustment value is shown in the lower
line of the menu (read-only).
In the Setup Mode (see Appendix A), it is possible to specify the value
in millimeters of the ribbon supply roll for the ribbon sensor. When the
diameter of remaining ribbon supply roll reaches the set value, an SNMP
trap is sent to the printer's home page, provided the printer has an optional
EasyLAN connection. Range: 0-80 with preset values at an interval of 5. A
value larger than 80 sets the ribbon sensor to 0. Default value: 0
The ribbon low sensor can also be set using an IPL command:
<STX><SI>kn<ETX>
There is no facility for adjusting the sensitivity of the ribbon sensor in IPL.
