HP Officejet Pro 7730 (Wide format) prints a black line at the left paper edge

[ako51]

My ink-printer HP OfficeJet Pro 7730 (wide format) prints since recently a black line at the left paper edge, but not on page 1, if there are more sheets to print.

What`s the reason and how can I eliminate this?

Thanks for soon reply.

Printing on A3 or A4 you get black line?

Thanks for reply.

It occures only with A4, not on A3.

I`ve just seen, that it is only with Programms like Word, pdf-files, excel.

If I print from websites, it`s ok.
