dots on printing

[Sandersan]

Small colored dots appears on left side og the paper when printing. Also appears when copying and printing varoius test and cleaning pages. Appeers in B/W when printing B/W (although fewer dots).

They seem consistant and regular - not smoothered as if it were "ink" in the wrong places inside the printer.

Anyone have tried this and solved it?

Best, Mikkel

Likely a failed cartridge, based on the color of the dots I would say black cartridge. The dots are fairly close together so could be something on the mag roller inside the cartridge. If you remove the cartridge and look at it you will likely see black dots on the drum (green blue cylinder on bottom).

HI and thanks for the answer. It might not be visible on the photo, but when printing something in color, the dots that appear will be i different colors (the picture), when printing i B/W the dots are fewer and in B/W. Do you still think it can be the black catridge?

Measure the space between the dots and compare to the defect ruler below.

Thank again! The distance between the dots vary. 7 mm. between som , 10 between others, and 3 between other again. So unfortunate it doesn't fit this table.

I would check all the drums closely. If I had to guess something went through the printer and left debris on multiple drum units.
