Stripped screws are just one issue a printer technician has to deal with. The reason screws become stripped are as follows.
- Worn Screwdriver Tip
Yes, a screwdriver tip can wear out. The sides get rounded and don’t fit as snug as it should and will slip off the screw and round the screw head stripping the screw.
Using the Wrong Size or Type Driver
Working on Hewlett Packard printers the screwdriver of choice would be a Type Number 2 Phillips Screwdriver. I worked for years and was oblivious as to what size and type of screw driver I was using.
- Some copiers use Japanese type screws. To more easily tell the differance between the two there should be a small dot or tiny hole on the edge of the JIS type. Here are the differences of JIS (Japanese Industrial Standard ) and Phillips.
- Not Applying Enough Pressure
If a screw has never been removed, they are locked in very tight. Not applying enough pressure will round the screw heads and strip the screw.
Removing the Stripped Screw
You will need a regular blade screwdriver preferably one that you don’t care about and a ball-peen hammer. Any hammer will do, but a smaller size will be easier to work with.
NOTE: To remove most screws you will need to drive them “Counter Clockwise”.
1. Take the driver and hold it straight on the edge of the screw. You need to hit the screw with the screwdriver blade enough to cut a notch in the edge of the screw . This notch will help keep the blade from just sliding off for the next step.
2. Place the blade at an angle that will drive the screw in a counter clockwise direction in the notch of the screw you created in the previous step.
3. Hit the screwdriver until you notice the screw break free. Replace the stripped screw with a new screw and you are done.
I believe there could be an instance where the screw is in such a place or angle that you cannot get the edge of the screwdriver where you can use this method. I have been lucky because I have always been able to get the screw out. There are other methods such as drilling, using a dremmal, but for printers or copiers this method should take care of it. If you have a story or experience with removing or not being able to remove a stripped screw, please let us hear about it.
