Samsung CLP-775ND Printer - Vertical streaks ?

[Davexxx]

I have a Samsung CLP-775ND CMYK (Win 10 Pro) printer which produces some feint vertical streaks (most noticeable with colour content), even after cleaning the glass panels behind each of the toner cartridges and also running the 'clean fuser' process (test page attached).

If anyone has met/solved this problem before, then I'd be pleased to receive details. TIA

Dave.

The solution has been to replace the Cyan cartridge (25% depletion = 653 pages printed, installed May 2018).

A second problem, feint vertical sections for the Black cartridge, couldn't be remedied by removing and shaking the cartridge. This, again, was solved by replacing the Black cartridge (39% depletion = 1718 pages printed, installed April 2019).
