SOURCE: cleaning inside of glass scanmaker 4800
OK Just Stupid (G).... Open the lid, pull it up and off and you will see two screws below the hinges. If you have decided to purchase another scanner already, you are clear to proceed. Take these out, pry the halves apart until you hear a click. Push the upper section toward the control panel and the will come apart like a freshly caught oyster.
I would not only clean the inside of the glass, but would get a can of compressed air and blow the heck out of the area below the black thing. This should get most of the dust off of the mirrors (3).
I took mine apart and cleaned them, but, if you had problems opening the case, I definately would not try taking this assembly apart. It'll make you cuss.

You can remove and clean the glass by first lifting off the scanner lid. Then pry the control panel bezel off and look for a square hole toward the front of the panel. Insert a screwdriver in this hole and press down then slide the panel toward the front of the printer. It should then lift off and you'll see a ribbon cable connected. Pull it out gently and set the panel aside. There are three T10 torx screws. Two at the rear and one at the right front. Carefully lift the glass assembly up while inserting a flat screwdriver in the left front edge to seperate. Lift the glass assembly off and clean as necessary.

As per my knowledge, you cannot clean the inner side of the glass untill you are expertised because it is all machine made and it depends on the aligning og the carriage which moves too and fro if the allignment is spolied then you will not be able to print aswell.
It is always recomended to cover the All-In-One.
And if your printer is in warranty you will get it replaced for free.
If not you can get a Out Of Warranty Upgrade from HP.
Call tech support and check the same.
Good Luck
SOURCE: copying is extremely slow but printing speed is fine
press the menu button, and then the copy option, under that you will find copy speed , see if that resolve your issue
