6.2.1 Cleaning the inside of Head Unit
Outline
Since a water-based transportation liquid (S-46) is contained in the head on factory shipment, this will react with the
solvent ink to form a precipitate.
Therefore, cleaning the inside of head unit with the solvent-washing liquid (MS washing liquid) is necessary before a
new head is installed.
Work procedures
1. Remove damper assy from cleaning Jig in the head.
2. Charge Syringe with 12-16 cc of the washing liquid exclusively
used when replacing the S head.
Types of wash
The washing liquid exclusively used when replacing the S head:
M005026
3. Fit S-damper assy again with syringe.
4. Insert it into Damper Connector on Head.
5. Slowly pour the washing liquid.
Pour 3 to 4 CD of the MS washing liquid into each nozzle in
about 30 seconds.
6. Use waste cloth to hold the liquid that spills out of nozzle.
* Conduct the aboves for every nozzle (x8).
(Charge the syringe with washing liquid through each inlet of 4
nozzles.)
Use protection glasses and gloves during works.
Depending on the working condition, ink may reach your eyes or your skin may be roughed due to ink.
Be careful of the washing liquid, used for replacing
the S head (M005026), dripping when taking out and
putting in the damper. Especially, dripping on the
FPC connector may damage the head.
Pour the washing liquid slowly, or the Head may be
damaged.
Do not touch the waste cloth to the nozzle surface,
nor rub it with the waste cloth. Both may cause
discharge failure.
