4. Once it is certain that the printhead is recognized, the printer will purge the ink tubes if they are empty.
It will also fill the printhead.
“Preparing the printhead for first usage”
If the process finishes OK, the printer will flag the printer tubes and printhead as filled with ink.
If during the process the printer detects that a cartridge has been removed it will show the message “A
supply has been removed” and it will go back to step 1.
After this step, all ink tubes should be completely filled. The circles on top of the printhead should also
look filled.
5. At this point, the printer will run 2 checks to validate the start-up: first will check for ink pressure and
second for printhead temperature while spitting. If the pressure fails, it will be logged as a SE 93.0.n:10
in the service plot (where n is the failing color). If the temperature check fails, it will be logged as a SE
93.2.n:10 in the service plot (where n is the failing color). The SE are not shown in the front panel. In
both cases, the printer will request to Reseat the printhead. After the reseat the printer will try to fill
again the tubes and printhead by going to step 3.
n indicates the missing color:
●
n=0 stands for photo black
●
n=1 stands for gray
●
n=2 stands for matte black
●
n=3 stands for cyan
●
n=4 stands for magenta
●
n=5 stands for yellow
6. After this second trial, the pressure and temperature tests will be repeated. If the pressure fails, it will
be logged as a SE 93.1.n:10 in the service plot (where n is the failing color). If the temperature check
fails, it will be logged as a SE 93.3.n:10 in the service plot (where n is the failing color). The SE are not
shown in the front panel. In any case, the printer will move to step 3 and try to execute it.
