I inserted the new cartridge and since then the printer no longer respects the spacing from the top edge of the sheet when I print doc and pdf files. Scanning works smoothly and so does the "copy" function, but if I create a text file that provides 2 cm of white space between the text and the edge of the sheet, the printer produces a copy with the text that starts right at the edge of the sheet and ends 4cm from the bottom edge of the sheet. The other side edges are regularly respected. I also tested it with doc and pdf files produced a long time ago and I still get this result. What maneuvers can I do to solve the problem? Thank you
