HS-1800 Inconsistent Scan Issue

[RickyG]

Hello, 

I have recently run into an issue when scanning 120 on my Noritsu HS-1800. The problem persists no matter which way I orient the film (backwards, emulsion side up, etc.). The problem has occurred on many different rolls, but happens to be most consistently visible on 6x6. 35mm does not seem to have this issue.

Things I have tried so far:

Switching out the film mask

Switching out the lens unit

Cleaning all of the anti-dust glass surfaces (with air/cloth/sensor cleaning kit)

Checked LED RBG levels (which were normal)

Film position calibration

Regular scanner calibration

AFC Cleaning

 

Something I have not tried yet, but I'm aware of is the focus adjustment using the MFC Crop Card. 

If anyone has any advice, tips, or recommendations please let me know!

 

Thank You !

Maybe is related to rollers from the carier? Or bad light?
