probably the laser unit ,

replace the LSU (laser unit)

This means that the laser unit inside your printer has failed. It costs around 100 dollars for the part and it needs to be installed by a trained technician. Best idea is to buy another printer. Sorry.

Check fuser, Check board, fuser not set correctly or Fuser not set this model.

you have to replace scan unit ,black box located under top cover

When sending document to my HP LaserJet P1505, the engine scanner error message

suspect either worn ADF(automatic document feeder) pickup roller or there is a jam in the ADF unit where the paper feeds to the scanner.

I would update to the latest adobe acrobat reader and see if that works.

Scanner error 6

This is laser scanner error message. The document is not being read from the data being sent. This could be a loose or damaged cable or bad scanner assembly. You can open it up and look for loose cables or connections to the board but otherwise if the scanner assembly is bad, it may require replacement. This should only be accomplished by a service professional as it is not a user serviceable problem.
