9.6 Time Axis Synchronization (POC)
1 Time Axis Synchronization (POC)
(1) This function is applicable to 2-pen, 3-pen and 4-pen
types. In the standard printings, data at the same
moment are printed on the chart paper with time axis
gaps due to the difference in pen positions between 1
st
pen and 2
nd
to 4
th
pens. (When POC = OFF)
(2) The time axis synchronization functions to store the data
of 2
nd
to 4
th
pens for the gaps and to print the stored data
after the chart paper is fed to the printing start point of
the 1st pen. (When POC = ON)
(3) The time axis synchronization is not available in 1-pen
types.

G1: Even when the printing is off, the
data for the gaps to 1st pen are
stored in memory.
G2: The data for the gaps to 1st pen,
which have been stored in
memory in the printing off, are
printed.
