Clear Nozzle; Flush Nozzle; Flush Shut Down - EC-PACK EC-JET 1000Pro Manual

Clear Nozzle

7.6
This option allows you to specify the number of Clear Nozzle sequences you wish to run on the printhead.
A minimum of three Clear Nozzle sequences is recommended in an attempt to clear a blockage or
obstruction. The routine of three Clear Nozzle sequences should be repeated no more than 10 times.
The following message will appear in the status line of the display while the Clear Nozzle sequence is
being performed:
"Clearing Nozzle: Please Wait"
During this cycle, the print head must be inverted and the correct type of solvent applied to the nozzle.
The procedure for clearing the nozzle is described later in this manual. (See "Troubleshooting – Clearing
the Printhead Nozzle")

Flush Nozzle

7.7
Commonly we recommend flushing the nozzle after clearing. This is to make sure the nozzle is
unblocked. When flushing the nozzle, the status line will display:
"Waiting for nozzle flush"
The nozzle will be flushed automatically. The flushing takes about 3 minutes and after that the solvent
will be spurted out from the nozzle, the status line will display:
"The print has stopped."

Flush Shut Down

7.8
The Flush Shutdown routine introduces solvent into the print head and nozzle, during jet shutdown, to
remove any ink in preparation for a period of non-use. The option has three settings:
Off This is the disabled setting. When set to Off, the printer will not carry out the flush part of the
flush shutdown routine when the jet is stopped.
On This is the enabled setting. When set to On, the printer will carry out the flush part of the flush
shutdown routine when the jet is stopped.
Auto This is the default setting for normal operation. In this mode, the decision as to whether or not
a flush shutdown is performed is dependent on the time since the previous flush shutdown, as
follows:
●
for ethanol inks, if the time since the previous flush shutdown is less than 40 minutes
(80 minutes for a 4 -meter conduit), a non-flush shutdown will be performed.
●
for all other inks, if the time since the previous flush shutdown is less than 15 minutes
(30 minutes for a 4 -meter conduit), a non-flush shutdown will be performed.
NOTE: For a successful overnight shutdown, the printer should be run for greater than the times
specified above. As with any shutdown routine, it is most important that the printer is allowed
to complete the full routine and is not switched off before the following message is displayed:
"Jet Stopped: You May Now Switch Off"
