That is likely so.

So, the 400C can only be T609K, right? I´ve never had personal contact with any other thanthe 400C.
It seems to try to focus on the disc. So why not just give it the correct values to save it the trouble of doing that?

If the lasers read just fine after a minute, isnt that weird for an adjustment situation? I think we will be down to hardware problems in the end.. but I wish i´m wrong
They're software tools. It seems like they're used with actual measurment tools (i.e. jitter meter). The discs used are (expensive) adjustment discs.

I´ve heard of those tools, but never knew exactly what they were. Are they like super special discs with maximum quality to optimal laser tuning? or is just some software tools?
You can use (good) PlayStation 2 game discs. Maybe you shouldn't use DVD+R discs though. To begin with, the early models don't seem to support DVD+R discs well.

If good discs are used, can I use very new PS2 original games and Verbatim DVD+R?
I don't think that lenschanger has such a facility (there are no known commands on the PS2 side for adjustment), but it does manipulate the EEPROM to allow you to change the optical block type. The values are from other consoles, AFAIK.

I´ll try not to burn the house down ... in alternative, i´ve read about Lenschanger for lens update. Can it do a similar job with this detection problem?
Unlike lenschanger, PMAP issues the command to load the defaults for the SANYO/SONY optical block.
The update values were taken from the SONY tools. If you're referring to the EEPROM updates, then yes... perhaps lenschanger does have such a thing.
The tray has two screws on most models; one for tangential and the other is for radial skew.

What kind of relation does this adjustment have with the white knob and screws in the laser disc tray?
You need to adjust both of them until you find the sweet spot - the position that gives the lowest jitter rate.
Only the B-chassis (SCPH-30001, GH-004/GH-005) had the AUTO-TILT motor. That model only requires manual-adjustment for tangential skew. Unfortunately, it only existed in the US, as one model.
Unless I remember it wrong, you're supposed to first begin with the electric-circuit adjustment, to adjust the gain level. After that, then you try to adjust the mechanism (tangential and radial skew).

If it gives many Jitter errors, I will have to adjust the knobs and the pots in the laser?
The pots on the optical block shouldn't have to be adjusted with.
