KEY TO CLEAN
4-5 When Not in Use for a Prolonged Period
Keep Performing Maintenance
Switch On the Power Once a Month
Switch on the sub power once a month. When you turn on the power, the machine automatically performs some
operations such as those to keep the print heads from drying out. Allowing the machine to stand completely unused
for a prolonged period may damage the print heads, so be sure to switch on the power to perform these automatic
operations.
Keep at a Constant Temperature and Relative Humidity
Even when the machine is not in use, keep it at a temperature of 5 to 40˚C (41 to 104˚F) and a relative humidity of 20
to 80% (with no condensation). Temperatures that are too high may degrade the ink and cause malfunction. Tempera-
tures that are too low may cause the ink to freeze and damage the heads.
Alarm Feature
This feature is to remind you to switch on the sub power once a month. When the machine
remains unused for about one month, this screen appears and a warning beep sounds. If
this screen appears, switch on the sub power. When maintenance operations finish, switch
                                         off the sub power.
This feature operates when the printers main power is turned on. We recommend leaving on just the main power to
the printer even when the machine is to remain out of use for a prolonged period.
Important Note on Draining Ink
This machine has features for draining internal ink and for performing washing using cleaning cartridges, but they
should never be used except in special cases. Allowing the machine to stand without ink for a prolonged period may
damage the heads, even if internal washing is performed. Once ink has been filled, then as a rule the ink should never
be drained.

4-6 When Moving the Unit
Procedures from Preparing to Move Through Reinstalling
To move the machine, you must completely drain all ink inside the machine and secure the print heads in place with
packing materials to protect them. Attempting to move the machine without first doing this may result in damage to
internal components due to leaking ink or damage to the heads.
This operation requires eight UNUSED SOL INK cleaning cartridges. Have these on hand before you start.
For information on how to remove and attach the various items, refer to the Setup Guide.
Important Notes on Moving
➢Be sure to use SOL INK cleaning cartridges. Use of any other type may result in breakdown.
➢Once the preparations for moving are complete, move the machine and fill it with ink with as little delay as
possible. Allowing the machine to stand without ink may damage the heads.
➢When moving the machine, keep it at a temperature between 5 to 40˚C (41 to 104˚F) and at relative humidity
between 20 to 80% (with no condensation). Failure to do so may result in breakdown.
➢Handle the machine with care when moving, keeping it level (not tilted at an angle) and preventing it from
striking other objects.
