[Carriage Guide Axis]
Unlike the previous EPSON ink jet printer models, 2 carriage guide axes
support the whole carriage in the Stylus Pro 5000. Also, since eccentric
shafts are used for both guide axes, more sophisticated PG changes are
possible. Following picture shows its concept.

Figure 2-3. Concept of PG Mechanism
As it is shown in the figure above, it is understandable that the PG
mechanism of Stylus Pro5000 equals the flying time for all nozzles.(Flying
time means the time span that ink is discharged and until it reaches to the
paper.)
