top/bottom density of printed sample

[ar17]

hope to get help. tried to measure the solid density of my printing and found out that the tail end (bottom) is heavier (1.88) than the top solid which is 1.72. is this normal or do i need to fix or adjust something to make it balance from top to bottom? this is for my black unit but it also gets same issue with cyan.
hope to get answers or solutions asap.

I don't know the tolerance between lead edge and tail edge but you can try the ink charge timing to reduce it.

the more rollers the unit has to carry the ink to the sheet the more consistent the density will be on the sheet
