CLP-680DW Printer Magenta Smearing

[KC89]

My Samsung Colour Laser CLP-680DW printer has started to smear magenta (pink) marks on the right-hand side of a printed page if I print in colour.  If I print in black only there is no smearing.  The smear markers have a regular spacing of about 8 cm.  I have examined the magenta cartridge which does not appear to have any build up of toner.  Any advice would be appreciated.
