[SOLVED] Hp laserjet pro giving less than half prints.

[mrsinghsolicitor]

As I got my hands on a second hand printer (Hp colour Laserjet pro m252dw) and bought two aftermarket toners which it accepted, but afterwards when I tried printing after cleaning, only some part on the corners are printed and rest of the page is blank with blue spots on the page.
What shall I do in that case?

please suggest me?
Thank you

1. I personally have never had good luck with aftermarket toners.
2. Might need a new drum.
3. Something may be misaligned.
