Hello everyone! I have a printing problem with my HP LaserJet MFP Pro M148dw
After printing I see that in the sheet there are small black dots spaced at regular intervals (see image).
I can't understand the cause of the problem.
Can anyone help me please?
Thank you all

Those are likely cause by a defect on the drum unit. You can Google repetitive defect ruler for your printer and you will find a list that tells you based on spacing which component is bad.
