Printed only 5000 pages on my Gestetner Aficio c7528N, and than after bringing it to my new office it stops to print magenta color.
After checking magenta development unit is not rotating.
It is not possible to do "Color Registration - Auto Adjustment" it comes message "Failed".

On Motherboard are 3 LED lights, one is green, other is orange iand the third LED is red.

There was a lot of magenta toner all over development unit pump, but all is now cleared, without any good result.

Any help, please...?
