[Misc] IRC 6800 having margin problem

[Dis]

Hi all, i done setting of margin before this, but after i change registration unit due to paper jam issue, the margin run out when i am printing and copy.
i tried service mode COPIER >ADJUST > FEED-ADJ > REGIST
setting to minimum -50, but still not enough, it left about 4mm to go.
any other setting that i can do for adjust please?

In advance I thank for All answers
