Manual Head inclination
adjustment (Horizontal)
Correct inclination of the Print Head in the CR
direction. Print the adjustment pattern, and visually
check the pattern to see if the adjustment is needed.
To correct the head inclination, turn the cam.
If this adjustment is not made, print quality problems such as
misaligned lines, grainy image, banding, or color
unevenness may occur in the scale of Print Head surface
area.

Manual Head slant
adjustment (Vertical)
Correct slant of the Print Head in the TF direction.
Print the adjustment pattern, and visually check the
pattern to see if the adjustment is needed. To correct
the head inclination, turn the cam.
If this adjustment is not made, the gap between the Print
Head surface and paper is kept uneven (e.g.: the gap at the
front side is wider than that at the rear side), and causes
irregularity in size and position of printed dots. This may be
observed as print quality problems such as grainy image,
banding, or color unevenness.

PG Check/PG Adjustment Adjust the platen gap using the thickness gauge.
When the PG is out of standards, the following symptoms
may occur.
If the gap is too wide:
Unstable ink droplet paths or misaligned dots occur,
which causes low printing quality such as banding,
printing misalignment, or grainy image.
If the gap is too narrow:
The head rubs paper.

Discharge
Discharge ink from the ink path. Execute from the
Service Program.
If ink is not discharged when instructed to do so before
removing parts or units, ink may leak from the printer and
contaminate surroundings.

Tube inner cleaning
Clean the ink flow paths to resolve the solidified ink
in the paths and clogging of nozzles of the Print
Head. Or, when leaving the printer unused for a
long period, doing this in advance can prevent ink
from getting solidified. Use the Cleaning Cartridge
for service and the Service Program.
If the printer is left unused for a long period without doing
this after discharging ink, the ink left in the ink flow paths
may get solidified. Once the ink becomes solidified,
charging new ink may become impossible or dot missing
may occur.

Initial ink charge
Charge ink in the ink flow paths. Execute from the
Service Program.
If this is not executed after discharging ink, air bubbles will
remain in the ink tubes and may cause dot missing.

Pulley and TF belt
position Adjustment
Check if the TF belt operates in the middle of the
pulley.
Since the accuracy of the TF feed deteriorates, horizontal
lines may occur.
Since the durability of TF belt lowers, the TF belt may be
broken.
