TECHNICAL DATA
1.2.1
PRINT UNIT
The printing device consists of a needle matrix head with overheating protection sensor fitted on the transport
carriage; contrast is provided by a spring-loaded deformation bar that permits adaptation of vertical position to
document thickness at the printing position.
Other features include faster speed of the printhead, increased to a maximum shooting frequency of 2295 Hz,
and a new ribbon with a life of 10 million characters.
The PR2
plus printing device consist of a needle matrix printhead that operates in serial mode and is fitted with
a overheating safety sensor. If the critical temperature threshold is exceeded, printing is interrupted.
To prevent this situation, it will be possible in future to introduce a forced ventilation device. The printer also
features an operating mode that, when a predefined temperature is reached, slows printing until the printhead
returns to normal conditions at which point printing restarts at normal speed.
Snap replacement of the printhead is not envisaged.
