Curious, why try cleaning the lens? Were you having difficulties reading discs?\n\nI'd suggest getting a new CD drive. DVD/CD burners are inexpensive. See source link.

Use lint free cloths and any Xylene based cleaner (I do not the brands available in your country). You may also use the cleaner liquid available to clean contact lenses. Make sure the glass is completely dried up after cleaning. The mirror mostly located below the lamp. If you see dust on it you may clean it with same cloth and solution. This mirror is front coated one and very much prone to scratches.\n\nFor scanner error it might be some other problem, like driver, twain driver, connecting cable related.

Go into remove/hardware.\n\nRemove the hardware from your system.\n\nUnplug the scanner.\n\nThen reinstall as if it was a new piece of hardware.\n\nGood Luck!

very carefully\nremove clip and unload weapon\npull back bolt and look down barrel to make sure is is unloaded.\ntake your cleaning worm and let sabot down barrel and pull the swab thru. use solvent and re-pull worm swab.  Get aerosol spray of Remington action cleaner and spray into opened action till gunk drips out and allow to air dry, then wipe down.\n\nUse Internet for further strip down instructions

It looks like a lot of dirt has accumulated on the lens. You should buy those lens cleaner Cd's and follow the instructions on them to get them cleaned.\n\nElse, it could be a lens problem and you may have to replace the drive.
