Strange Epson 10000CF problem (streaking ?)

[Martin71]

Hi All !

My printer developed this issue immediately, there was no build up to this. One print was fine, the next...

In short: Whilst printing, yellow lines/bars appear all over the print (vertical). This happens at anything over 360DPI, at 360 there is no streaks at all. I have re-installed the drivers to no avail.

Is this a head problem ? The printer - not mine

Any advice would be greatly appreciated as this is driving me insane...
