Tip & How-To about Hawking Contex HAWK-EYE Cx Scanner

Scanner Tips 2 " Don'ts "

Never apply solution directly on the scanner glass. If you find that the glass is dirty or has a slight dust or smoke film underneath and on the inside, do not unscrew the lid and try to clean it from inside. It's always advisable to call an authorized service center.
Never use abrasives, isopropyl alcohol, benzene, acetone etc on the scanner glass, as this will streak and cloud the glass, and can Even cause damage.
Never place your scanner near heating vents or windows, or other locations where moisture might affect its functioning. Also remember: If you are moving the scanner from one place to another, make sure that the transportation lock is enabled, as this prevents the CCD array mechanism from moving. Push down the lock, which is located at the back of the scanner. Remember to unlock the scanner before you attempt to operate it, or you may end up damaging it.

How to clean the underside of the scanner glass on an HP4400C flatbed scanner.


This is acutally easier than it looks. I just had the same problem with a cloudy film starting to form underneath the glass on my older HP 4400C scanner.

First completely remove the hinged top lid by lifting straight up on both long ends of the lid - notice the 2 hinges on the back end of the lid will come straight up and out of the body of the scanner, still attached to the lid.

Next look down inside the 2 hinge holes (on the main body of the scanner where the lid hinges just came out of) and you will see a screw in each hole. Remove both screws using a phillips screwdriver. This will allow the rear end of the scanner to come apart enough so you can now lift it up a few inches to separate it and get your hand inside there to clean the underside of the glass with a soft cloth - BUT JUST REMEMBER THE FRONT END OF THE SCANNER WILL STILL BE CONNECTED, so don't pull it too far apart because it could snap and break something that is still holding the front end together. (I could not figure out how to separate the front end piece, and then I realized I didn't have to).

So on the rear end of the scanner, now carefully pull the light upper colored plastic apart from the lower dark plastic just enough so you can get your hand inside the compartment and use a soft cloth to clean the underside of the glass. I just used a small piece of an old cotton t-shirt with a couple little dabs of water on it and then just kept rubbing the dirty areas on the underside of the glass over and over until all the dust film/streaks disappeared and the glass was once again clean and all clear.

Then gently lower the glass back down and line up the plastic pieces together on the rear end and put the 2 screws back in the hinge holes, and then reinsert the hinges in their slots and lower the lid back on top of the scanner glass and it is ready to go again !!

Hope this works for you like it did for me.

HP 7410 Scanner mirror dirty


you can go tru this extract ON HOW TO FIX IT
clean the glass
Dirty glass, from fingerprints, smudges, hair, and so on, slows down
performance and affects the accuracy of special features such as Fit to Page and
Copy.
1 Turn off the unit, unplug the power cord, and raise the lid.
2 Clean the glass with a soft cloth or sponge slightly moistened with a
nonabrasive glass cleaner.
Caution! Do not use abrasives, acetone, benzene, or carbon
tetrachloride on the glass; these can damage it. Do not place
liquids directly on the glass. They may seep under it and damage
the unit.
3 Dry the glass with a chamois or cellulose sponge to prevent spotting.
clean the lid backing
Minor debris can accumulate on the white document-backing located
underneath the unit’s lid.
1 Turn off the unit, unplug the power cord, and raise the lid.
2 Clean the white document-backing with a soft cloth or sponge slightly
moistened with a mild soap and warm water.
3 Wash the backing gently to loosen debris; do not scrub the backing.
4 Dry the backing with a chamois or soft cloth.
Caution! Do not use paper-based wipes as these may scratch the
backing.
5 If this does not clean the backing well enough, repeat the previous steps
using isopropyl (rubbing) alcohol, and wipe the backing thoroughly with a
damp cloth to remove any residual alcohol.
clean the exterior
Use a soft, damp, lint-free cloth to wipe dust, smudges, and stains off the case.
The interior of the unit does not require cleaning. Keep fluids away from the
interior of the unit as well as the front panel.

Small white dots would indicate progressive failure of the CCD[sensor] or perhaps ingress of dirt to the inside of the glass. hard to say exactly with out seeing the machine.
