i use the hp officejet pro 7720 and print with a3 glossy photo paper (i've always used the same paper and no issues) suddenly the printers started smudging the ink as it spits it out, it smudges in the exact same place every time, i've checked and there doesn.t seem to be anything stuck inside. just replaced the printhead too as was having issues with it streaking but this has been happening before i changed printhead. also leaving black marks all down the back of the paper when i print in a4

The smudges on the front are they present when printing the same job on a plain paper? Looks like a paper issue to me.
The smudged on the back side are on the printers rollers, it will clean itself out if you print several empty sheets on a plain paper.
