MX-5001 N white dots on B/W prints

[jonathan3205]

Hi, I have a problem with a MX-5001N. When printing in B/W there are white spots all over the page. But when printing in color there is no problem. This machine only have 67000 prints on B/W since the last developer change and only started to present this issue since 2 months ago.

Thank you for your help and advice.

Problem with the toner unit or the toner brand/type?

Yeah I wish I could afford it, but here in México It is super expensive and difficult to find it.

What should I try then? Change the developer or the toner?

As a side note recently switched from a brand I do not remeber the name, but was printing fine and then started to use toner BlackStar and it was around that time when the prblems began.
