Good day to every body.
I hope you will help me to make things done appropriately.
 I've got an issue with my Roland RF-640
Firstly I've bought the list of things:
- a new print head DX6 (absolutely new)
- dampers
- inks (bag bulk)
- clean solution
- a pump for solvent. 
I've connected the pump to wire tubes and cleaned each channel with a cleaning solution. I didin't want my new print head to absorb the dirt that had been collected for years. When it's been done I changed dampers to new ones.... and then installed the new print head.
Having done FILL INK function.... I tried to make a nozzle check. It was late time, nozzle check wasn't impressive, half of them were missing.... I switched the printer off and went home.
By now, I inputed ID RANK and done: FILLING - 2 times, POWERFUL CLEAN - 3 times, Bi-Dir.calib., adjusted FLUSHING POSITION. 
As for ALIGNMENT HEAD - it's quite tricky and dubious. According to a service manual misalignment is compared one column of nozzles with another, meaning that the whole colums of lines in the right should be straight (or upper or lower) to the left side. I've got misalignment at the last row, and it looks like more deflective than misaligned. As long as I don't have a normal Nozzle Check... how can I align the print head?
There is a sequence which should be done after replacing a new print head:
So the second step as far as I understand is I should ascertain that all nozzles fire inks well.
As for misalignment 
and should be
I can assume that misalignment is not my case.... and it is just deflection which looks like misalignment.
I've taken a photograph on DSLR camera... the file's size is around 18Mb.... please, check it out and tell me what you think.... 
All nozzles are firing inks however some of them firing inappropriately (deflected).
Forgotten to mention.... a cap and wiper have been cleaned, but not changed.
Thank you for any help

Did you do the things suggested?

Well, actually I've done everything it is written in the manual (step-by-step), however, as I said in the thread, I have done head alignment since two colums are straight.... 

As for misalignment 
and should be
In my case only two rows are not aligned since they I think deflected. Am I wrong?
May I ask you how you judge my test? I might miss the point... Sorry.

#update: I've taken a couple of photographs on DSLR

Who can help me with reading a .pec file?

A few things. That nozzle check looks far from a new head. You can forget trying to align that head if thats the actual nozzle check.

If I walked into your shop and you showed me that nozzle check, I'd tell you that you need a new head.

Do you imply that the printhead I bought is defective? Is it possible? The online shop I bought the printhead gives a year warranty... although I'm not sure if they are interested in changing the printhead after it has been installed and filled with inks...

Digiprint has good heads, not cosigning yours, but the ones I used from them.

I also think you will have a problem, because they only cover installation from a certified tech. There is no way of knowing a head is good or bad unless you install it. What Todd is saying that you will not clear up the deflections even with aligning the head. I would get there, but I at least like to see the head aligned before I deep six it. Todd tends to be faster at the bottom line than I am.
