Black impression on Sides

[anujdhingra]

Hi

I have used many printers for my home-office and after a little while all printers start having the same issue of marking black impression on both sides of the paper. I am not sure why this happens or of there is a solution to this issue.

Currently I am having this issue with Laserjet 2300 series.

Any help would be highly appreciated.

Several possibilities:
1. cheap or failing toner,
2. fuser,
3. transfer roller
