(1) Printing mechanism
The DL9300/9400 printing mechanism consists of a print head and carriage, a carriage drive mechanism, a
paper feed mechanism, a paper path selection mechanism, an automatic print head gap adjustment mecha-
nism, and sensors. The carriage includes a ribbon feed mechanism and the other sensors.
The printing mechanism uses five motors for driving the mechanism components so as to distribute the load.
The five motors each correspond to the platen, the tractor unit, the APTC mechanism, the HCPP mechanism,
and the print head carriage.
