Clamp position
adjustment
Check if the clamps are secured at the correct
positions between the CR UNIT and Ink Tube Joint.
If not, perform this adjustment.
Parts may be damaged during the CR UNIT movement if the
HEAD FFC or Ink Tubes comes in contact with a clamp.
 When the HEAD FFC has slack:
The HEAD FFC may come in contact with the Ink Tubes
and the tubes may be damaged.
 When the HEAD FFC is too tight:
The HEAD FFC may come in contact with one of the
clamps and the top or bottom of the FFC may be
damaged. (In such a case, a head related service call error
such as the thermistor error will occur.)

Tube inner pressure
reduction
Reduce the pressure in the ink flow paths. Doing
this prevents ink leakage that can occur when
removing the ink related parts/units.
Ink leaks when replacing a part that depressurizes the ink
path.

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.

Cleaning
Specify the power and the color from the Service
Program and execute the head cleaning.
When the cleaning is not executed, the following symptoms
may occur.
 Nozzle clogging is not solved and the printing cannot be
executed properly.
 Ink droplets are not fired and nothing is printed after the
Print Head is replaced to a new one. (Executing Initial
ink charge may solve this problem but it takes time and
consumes lots of ink.)
