Printer printing blank sheets

[Nick5562]

• My printer was working greatly,

One day i had paper jammed inside, 

Since then my paper first was printing badly, then printing badly and weak, now it just printing blank sheets,

Tried changing to new black cartridge, still fully blank.

Thanks

Sounds like there might still be some residue or damage from the paper jam. Try cleaning the printhead/nozzles if it's an inkjet or running a self-cleaning cycle. If it's a laser printer, check the toner drum for damage. Also, make sure there's no leftover paper bits inside messing with the rollers.

  this the photos, and inside the printer there is ink spilled, should it be like that?

Anyone know the problem?
