Laser beam error, caused by the "black" laser.(each color has it's own laser).

Most 49 errors can be fixed by updating the firmware on the printer. Your issue is very common, especially if you just updated Adobe Acrobat. Go to HP.com and search for drivers and software. As you list 2 different printers I do not know which one you have or I would link it. Once you get to the drivers page look in the cross operating system (bios firmware) section and you will find the firmware updates here. Download the appropriate one and follow the instructions in the read me file to install. Post back with proper model number if you have issues and I will provide a direct link.
You need to connect the unit via USB and then run the HP firmware update utility so that the current firmware can be installed. This error is usually caused when a firmware update is interrupted. Current firmware for this unit is 20100902.
