I changed all the components (DX5 printhead, capping station block and assy flushing box)
yesterday and do all the adjustment today with the adjustment wizard.
As I have said, my difficulty was to use OEM inks to perform this task [B]or not[/B].
Finally after a long wait because of a very strong and hot temp in my country,
I decided to use my piezo inks (methodology 3) as it was before the crash.
[U]Before changing the head I write with the wizard adjustment tool the new head rank ID.[/U]
Turn off the printer and start to dismount the head. With the Maintenance manual (a must need)
you have all the pictures to illustrate what you must do. So I haven’t take photos
to illustrate what I write :o
On the head block bracket, you have two tab to swing the head up/down and left/right.
Be aware about it and their positions, don’t touch them at this step.
This is not really difficult to change the head, patience and cool gesture is a good companion.
I have the new head in place and also I replaced the yellow damper because
I suspected some ink leak (despite dampers are news).
Now, I can change the capping station block and the small assy flushing box.
With a new head installed, it make sense for me to change those parts. New head, new “toilet”…
Once those material change realized, it’s time to inject inks through the new head and run
a first nozzle test. For this, I do an automatic purge with the use of the printer board. Menu/maintenance…
The winner is Meeeeee !!!
[I]The steps with the adjustment wizard:[/I]
[U]You must have this soft to do all the adjustments needed (Without this
tool, it’s completely impossible).[/U]
1_ Reset print head change and cleaning unit change
2_ Print two tests that permit the slant adjustment of the head ( up/down and left/right).
For me, the left/right adjustment was necessary. Here, You can touch one or the two “don’t touch” tabs
Of course, you must reprint the test and verify if it’s good.
3_ I proceed the head alignment by using "auto biD ". This adjustment use the sensor ink mark
to perform the task automatically.
Print new nozzle tests to see if alignment is good or not and detect possible “missing nozzles and band of brothers”
Running a first print and say “Hurrah”, congratulation, caviar and champagne!
1_ Print better than before.
2_ A “virtually” new printer. Enjoy!
In conclusion, I can say it’s not a problem to start directly with a new head and piezo ink
with this proprinter. I don’t know for others…
