Hi
I have HP LaserJet Pro 300 M375nw which produce some imperfection while printing. It always make vertical lines from the left and right in the same position. Also, before it used to print good in colour but black was faded, I shacked cartridges and now black is good but it horribly print in colour.
Which rollers do I need to check first? Can all rollers be clean with isopropyl alcohol?
