Useless cover hinges

How do you adjust the hinges so they actually hold the cover up? The cover has been slamming down and has caught my fingers several times.

Don't think you can - it has a fixed tension via springs

How to clean the underside of the glass in a HP scanjet 2400

Hi ,
You probably already found this :
According to it , you should normaly contact a HP technician to have the job done . Nevertheless , I succeeded to clean the underside of the glass inside a HP Scanjet 5470C wich seems similar to your model 2400 . If you take of the lid of the unit , you should find two screws in the opening of the hinges . Unscrew them and lift up the the whole top of the unit . You might encounter somme kind of resistance during the operation but I finally succeeded to get the it free that way .
Best regards .

Unable to close cover of scanner. Hinges are locked fully open. No information on how to unlock hinges

The scanner's lid pulls upward a bit, and can sometimes get stuck that way -- in that case, the hinges won't bend. Try making sure the lid at the hinge end is flush against the bottom part of the scanner.

How do you open case to clean inside of glass

Lock the carriage first! Remove the two medium-sized Phillips screws under the hinge and the small one over the small plastic cover plate. Remove that cover plate. Slide the top tray (glass and cover) off the frame by pulling laterally in the direction of the hinge. It will snap out if you work on it. Clean the glass. Slide tray back in and seat it securely. Put the large screws in to hold the carriage. You won't be able to screw them in if the cover isn't seated right. Now make sure the 5-conductor ribbon cable that is under the small plastic cover plate gets stuck back in the socket. You just push it into the tiny black socket. I think that tells the scanner what's going on with the cover. Then reinstall the cover plate. Now you should be good to go! Don't forget to unlock the carriage.

Expression 1680 Professional Flatbed Scanner: Transparency adaptor stuck in open position. The h...

Had the same problem. By lid I assume you mean transparency unit. To fix, it is necessary to remove the transparency unit from the scanner. Then IN A CLEAN AREA! with the glass side up unscrew the 6?screws that hold the top unit together. There will be a hinge assembly inside. You must remove it, clean it, and re grease it thoroughly. I used lithium grease from an aerosol can. Has not given me problem since. the whole process took about a half hour. just make sure you are gentle, and keep everything clean.

Cleaning underside of glass on 610 scanner glass has mildew on underside

Ok. Found this question on-line as I also wanted to know the answer. Couldnt find an answer so I just decided to have a go myself. It was quite easy really. Lift the lid upwards and gently push it backwards from the hinged end and it will unclip. With the scanner facing away from you, undo the only 2 screws visible at the back. Then gently lift up and push forward towards the front. You can see thru the glass 3 plasic lugs holding the front down. With a little wiggle the cover with the glass attached will come away from the slotted holes where the plastic lugs go. Clean glass an carefully replace lid in the reverse order. Pete

On the Canon scanner 7580, the lid is not closing all the way, which prevents scanning function. I believe the gray handle release that lifts the scanner and resets the scanner may be broken. How do you...

There grey handle does not reset the scanner. When you press, it pulls back the catch on both sides. If it is working properly, you may need to adjust the two small notches where the catch is held. You can slightly move it so that the scanner closes properly.

Filmy appearance and spots on the underneath of glass

Today I opened my V200 without much problems. First unscrew the two screws under the lid. Then turn the V200 upside down. Lift the base plate up, gently, beginning at the back (a little twisting is needed). Take care not to force anything. It took me 10 minutes. Fold everything open like a suitcase, then clean the glass inside...
To close again start with the front (sort of click system)

Door/Hinge is very tight, have to push down hard when scanning

Remove the transparency unit from the scanner. Then carefully remove the six screws holding the hinge. Use WD 40 to lubricate hinge.

Transparency adaptor won't close

Remove the transparency adaptor from the scanner bed (unscrew the two smaller screws, then slide back and off) and then remove the glass (and plastic frame) of the transparency adapter (there are six screws).


By the hinge there is a small white plastic switch. Usually the transparency adaptor hits this when it's closed, letting your computer know that it is ready to scan. What I did, as bcvideo did, was take duct tape and firmly taped the switch to the side of the transparency adaptor, using several small strips of tape.


The scanner works well now. You may need/want to put something on top of the scanner if it does not fully close.

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.
