Searching for clue about correcting the toner density especially for Magenta density. By looking at defective test page, there are indeed magenta toner band on the belt, after clean it, the magenta color still not align 20160812000750036.pdf.
Vcnt_[M] just 4.7 and Vcnt_[C] 5.1 just half default value(10)

thanks

That is well and truly out of colour reg.

I would start by manually cleaning the three ID sensors and checking the reflective bar under the transfer belt is clean, then perform a auto colour reg adjust.

If that fails there is a good chance that it's just too far out of reg.
In that case it would need to be brought back in manually.
When colour reg is close enough the auto line adjust should detect the pattern and successfully bring it back in tight.

BTW that printer is ancient.

Tks, 3 ID sensors quite clean at very beginning, because Process Control Result (3975-001) always successfully. Very good suggestion to transfer roller(Magenta){"the reflective bar"} and its terminal
