Banding on SG400 which is only 16 months old. Yes we have talked with Sawgrass but it seems they had a work experience kid on support. Banding only happened recently and we have cleaned everything from encoder wheel to capping station but no change.

Interestingly we changed from paper type "inkjet plain paper" to "glossy" and the banding virtually disappeared (both unidirectional) although still faintly appears.

Nozzle check is 100% perfect yet the banding is only showing on colours using cyan.

I am presuming that the head has a cyan nozzle issue but out of ideas and NO ONE has SG400 in stock anymore and if we need a new printer would rather go six colour so not another Sawgrass ink burner printer (i.e. SG500). EVERYONE is out of stock of Epson printers though for A4 sublimation Grrr.

Hence any ideas what this could be or is the printer a paper weight after only 16500 prints?

Or maybe a recent Windows Update screwed things up?

Kind regards
