Active Damper
Adjustment
Execute the calibration of the active damper from the
Service Program.
* Active damper is a function to reduce the carriage
vibration which causes the vertical bands by outputting the
waveform which has opposite phase from the motor
vibration.
The motor vibration/carriage vibration may not
be reduced, and the vertical bands occur.

Head ID Check & Input
Register the head rank ID to the printer using the Service
Program and check the currently registered value. Head
rank ID is the ID to drive the Printhead with the proper
voltage and correct the amount of ink droplets. 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 the result.
 Since the amount of ink droplets turns to be
unstable, dot missing or misaligned dots
occur while printing or flushing.
