Washing Sequence Flag - Epson Stylus Pro GS6000 Service Manual

Epson Stylus Pro GS6000

5.6.3 Washing Sequence Flag

This product is set at the factory to execute a washing sequence when turning it ON for
the first time. This washing sequence is essential to prevent quality troubles in the ink
system the first time the printer is used.
With the service program, setting the cleaning flag to "on" allows having a washing
sequence started next time the printer will be turned ON while setting the flag to "off"
allows skipping the washing sequence next time the printer will be turned ON and go
directly to the ink charge sequence.
Examples of use:
In case the parameters in the NVRAM cannot be backed up during a main
board exchange, the parameters of the new board are reset to the ex-factory
situation so the washing sequence mentioned above will be executed the next
time the printer is turned ON. In case a washing sequence was no required
(ink already charged, no cleaning cartridge available, etc.), setting the flag to
"Off" can skip the washing sequence and go directly to the ink charge
sequence. If necessary, the ink charge sequence can be skipped by modifying
the ink charge flag.
In case a printer is washed and the sequence stopped before the ink charge
(preparation for a transport, refurbishment, etc.), setting the flag to "On"
allows having a washing sequence re-started again from the beginning the
next time the printer will be turned ON. (Reset to the same situation as the
factory shipment.)
Never skip a washing sequence if the printer has never been
C A U T I O N
washed after its shipping: an initial washing is essential to
prevent quality problems on the ink system.
A washing sequence is recommended if the printer has been
used, purged then stored for more than a week. It is also
recommended not to skip the sequence if the printer will not be
filled with ink in the week after a repair.
