Hello,
Please see the two attachments, test print pages for HP1215, black where it clearly shows on the left hand side of the page, that spotty black mark from top to bottom.
I used a virgin core, did not change anything and used
SCC TRHp46-195-k
toner.
I used my own virgin core from my own machine which I use for printing some material that some customers request.
Thanks for your advise
José Robles
