Head ID Input
Register the head rank ID to the printer using the
Service Program or check the currently registered
head rank ID. Head rank ID is information
needed to drive the Print Head with proper
voltages so that proper amount of ink droplets are
fired. The ID is assigned to each head and listed
on the label on the head.
If the new ID is not registered after replacing the
head, the head ID of the older head is used and
the proper drive voltage cannot be set. The
following symptoms may occur.
Since the amount of ink droplets is not proper,
the color and density abnormalities are found
on prints.
Since the amount of ink droplets turns to be
unstable, dot missing or misaligned dots occur
while printing or flushing.
