bidirectional detail calibration setup overlapping lines are not within -20 +20 more like they could be +30

Hi All,
Not posted for a while.
My VS540I having weird issues.
This morning all prints have an apparent overspray.
Several medium cleans, still the same.
So I fit a new OEM cap top, wiper, felt, then doing a full service clean.
When I go into user mode, adjust bi-dir, detail settings and print the test, the direction lines never come together on No1,2,4 they appear it could be way past the +20 see photo
I then went in to service mode and ran the same test, it was the same.
I googled and read it could be the encoder strip, so fitted a new one, ran the encoder setup, calibration etc unfortunately still no change.
I've cleaned the encoder sensor, the feed encoder & sensor.
Is there a setting to get the service mode bir-dir detail settings to get the overlapping line closer to the middle and not way off to the right?
I'm at a lose now, need help/direction please.

if i remember correctly, that is a value that you input into the alignment procedure ...not +/- the existing value.

Hi Mike,
H1,2,3 &4 the test print give the bi-dir setting, you then go into setting and change it to the setting that has the overlapping line, as you can see from the photo, the overlapping lines are off the chart at possibly +25-+30

 

[MikePro]

first line looks like +15 to me, you're no2 line might be "off the chart" but not really... just cap it at 20, or try a little higher if you really want but I don't think it would be anywhere near 30.

no4 +15
no3 +9.
no2 +20-24
no1 +16

this forum saved my ass back in my mimaki jv3 days, but youtube is also your friend. found this alignment video if that helps.
edited to add: watching the video, it looks like the triangle indicates what your current setting is. adjust to new value and you should be off and running.
seems simple enough, hopefully you're not going through this process for some other print issues that don't appear to be remedied after alignment? no amount of alignment will correct an overspray issue.

Hi Mike,
Yeah I've done that, this photo is after I changed the encoder strip and before re-calibration. The scan left/right overlapping lines should be nearer the 0 to allow for adjustment either way, theres no clear adjustment when it's already over at +20

 

[MikePro]

curious. what's your nozzle test print look like?

 

[balstestrat]

Yeah, show us that.

 

[huddsphil]

Here you go, printer is half open in mid clean/diagnostic
A couple of nozzles are missing but in mid clean

You need to run the bi-directional alignment in service mode to zero out the user mode ones.

 

[huddsphil]

I've done that, but user mode doesn't give overlapping lines near 0, they all appear to be over to the right +20

 

[huddsphil]

So I've re-run the service mode bi-directional alignment but in user mode the overlapping lines are not available, way off beyond +20
Is there a setting to reset this so overlapping is nearer 0 so I have the ability to adjust?
