4.9 Setting the End of Reel Detection
The printer can detect the end of ribbon reel in one of two ways, reactive or predictive.
• Reactive mode: Stops the printer when the end of a reel of ribbon is reached and the
last section of ribbon detaches from the supply spool. This mode of detection may
suit majority of the applications, however, it is not possible to completely guarantee,
that the final product gets coded correctly as the ribbon breaks.
• Predictive mode: Monitors the amount of ribbon remaining on the supply reel and
stops the printer when approximately 5 metres of ribbon (+/- 2.5 metres) remains.
Operating in this mode ensures no products remain unprinted when the end of reel
is reached.
In case the ribbon breaks in the mid-reel, the reactive mode is always enabled to detect the break.
The predictive mode only takes precedent at the end of the reel.
To ensure that both detection modes work to their optimum, it is necessary to input the correct
values of the width and the color of the ribbon being used as different colors have different
thicknesses.
The ribbon operating mode parameter, Predictive or Reactive, can only be accessed via CLARiTY
Configuration Manager and the parameter called End Of Reel Detection must be set
appropriately. The default is Reactive mode.
The configured mode is displayed.
