Alarm Feature; If The Machine Has Not Been Used For One Month Or More - TDS EJ-640 Maintenance Manual

EJ-640 Maintenance Guide
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 operations such as those to keep the print heads from drying out.
Leaving the machine 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 degrees Celsius
and a relative humidity of 20 to 80% (with no condensation). Temperatures that are too
high may degrade the ink and cause malfunction. Temperatures that are too low may cause
the ink to freeze and damage the heads.

Alarm Feature

The alarm feature reminds 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 the screen appears, switch on the sub power. When maintenance operations
finish, switch off the sub power.
This feature operates when the printer's main power is turned on. Leave the main power switched on at all times even
when the printer is to remain out of use for a prolonged period.

If the Machine Has Not Been Used for One Month or More

If the machine has not been used for one month or more, refresh the subtanks. If you use
the machine straight away without performing his procedure, printing may be adversely
affected, e.g. printed colors may be unstable.
