Epson L800 lines at the beginning of the print and at the end

[Ink stained Fingers]

The only issue i have is why it dosen't print the nozzle check.

Sorry , but I have a small problem - you are posting a crop of a nozzle check print

printing the firmware version and the serial number - with black ink,
and a printhead creating such a fuzzy print needs some cleaning - at least for the
black channel even if the other ink channels are working fine.

You may check the conenction of the printer to the computer - e.g. changing from
wireless to USB or using a short USB cable instead of the long one, or connecting
the printer to another computer - Windows, yes - there are situations that printer functions
are not activated like regular prints - I have observed similar effects now and then, it is
a kind of start up signal which does not get the printer active but only regular print commands .

The photo is a crop only for example.
I can't even print the nozzle check from the printer without pc conection, from the printers buttons.
