Re: TASKalfa xx52/xx53 series light banding in feed direction
As Kyo_Oem has shown you, you failed to replace all the drive components. I was not aware there was an intermediate gear assembly between the Drive Unit and the DV.
Apparently though this is all that can be done from a replacement stand point, removing worn gears will reduce gear lash effects.
The jitter appears to be transmitted to the image also because of some play in the DV mounting and drive angles which were revised, but not in your model apparently. DV's are hard to turn under most conditions and it's this resistance that causes drive forces to be transmitted to the frame rather than the roller.
In fact, new dv's might be worse than old ones because of increased torque resistance of being new, but I don't think they could get loose enough NOT to transmit some jitter.
We all knew the jitter was from gear noise because the pattern matches the typical pitch of the gear teeth. Kyo_Oem has shown us that the jitter is not only transmitted to the DV roller, but to the entire DV unit and this was determined to be a design problem.
