    Red face Struggling with dots on prints

    Hi All, I am struggling with getting dots on my prints. I use Ultimaker Cura as my slicing software and most settings are the standard defaults. My prints has dots on them at the back. I am attaching a pic of a yorkie I printed. I decided to print the infamous xyz cube, and yes they are very obvious in this print, attached is the view of the front of the cube as well as the back. I am using a ender 3 v2 printer. Any suggestions would be greatly appreciated. What have I done: Upgraded the springs to remove bit of movement that was on the build plate. Spent hours on bed levelling.Any other suggestions. Thanks in advanceClydie

    Dots are typically caused by foreign material inside the machine (for example, paper dust, glue from labels or envelopes, paper clips, staples) sticking to or damaging the surface of the drum. Toner builds up on or sticks to these areas on the drum and creates black dots on the printed pages.

    How do you prevent the toner building up inside it? Is it easy to clean the internals of these machines?

    Thanks, maybe I was not clear, but it is more like blobs and pimples than dots. Look at the attached pictures.
