I have the Da Vinci Jr.  The tag is a paper tag I configured.  It was in the printer once, but did not work.  I have more of them.  Maybe, I should just try a new one.

Thank you for the help!

Also, what type of printer do you have and has the tag been in the printer before?

"44 -- First two bytes are the PACK number. The last two bytes are the RFUI."

I am not sure what the RFUI is.  Sorry for my ignorance in the matter.  I am learning as quickly as I can.

I missed the point
did you encounter any issue to overwrite  the value 0x14-0x17 to use other pla ?

assuming ^ means XOR , I can not  find again the 0x15 value with your formula
same for 0x16 value

It's a problem with endianness.

0x14: 0xF68D0200 this is 167414 (decimal, little endian)
0x15: 167414 ^ 1412567624 = 1412472766 (decimal) = 0xBE9F3054 (little endian)
0x16: (167414 - 3876923) ^ 824661077 = -824167954 (signed decimal) = 0xEE31E0CE (little endian)
0x17: (167414 + 6923923) ^ 1982026881 = 1984913416 (decimal) = 0x08604F76 (little endian)

If you're using Windows calculator you will have to reverse the hex codes to get little endian.

same problem

what I noticed, if I take the 4 value from the orange  board and I put as they are in the black board
there is an error : unknow spool

does anyone experiment this kind of problem ?
thanks by advance

I would initiate a small discussion/research again regarding pages [20;21;22;23]

As far we know the page 21 contains same data as page 20 xored with value 0x48123254
We will call it checksum. It's not real checksum I know, it should not be subject of the discussion here.

So, but what about the other two pages 22 and 23 ??

...

Does anyone have a clue?

Of course:

R = Remaining length
Page 21: R ^ 0x54321248
Page 22: (R - 3876923) ^ 0x31275455
Page 23: (R + 6923923) ^ 0x76235481

Testing and reading a lot in this forum I came across something.

If you print the filament completely empty, you automatically get the XOR keys.
