Power Off Sequence
There is a wait time of up to 2 minutes (depending on controller
condition) after the machine has been switched off.
This prevents damage to the hard disk, and lets the machine cap
the print heads.
A message is displayed, and goes off after the machine
completes its shutdown sequence.
The actual delay may be up to two minutes or much shorter.
Power off at Standby. Powers off quickly because print heads are
already capped.
Power off during maintenance cycle. Power off does not wait for
the maintenance cycle to complete. The cleaning cycle stops, and
the maintenance unit caps the print heads.
Power off during printing. Power goes off as soon as the job stops
and the print heads are capped.
Power outage. If the machine goes off due to a power outage, the
operator should check the position of the carriage immediately.
» If power is restored within one day, the customer should print a nozzle
check pattern, and if there is a problem with the print heads, try to
recover them using the print head cleaning and flushing procedures
described in the Installation section of the course.
» If the print heads are out of position for more than one day, the
customer should call for service. The print heads may need to be
replaced.
SW11: Horizontal Motor Interlock Switch
This small switch is attached to the top of the main power switch. If the main
power is switched off, this interlock switch will keep the circuit closed until the
horizontal motor stops operating, and then it will open the circuit to switch off the
power. This ensures that the carriage unit is at rest on the right side of the
machine with the print heads capped. (This causes a slight delay and a 2 minute
warning when the main power is switched off.)
