Look for a switch, or lever to unlock the scanner (behind it, maybe under the lid)

Why do I get an error message: Internal error occurred. Scan driver will be closed. Code:5,202,52?


Look at the bottom of the scanner and there should be a lock/unlock slider. Unlock it and see what happens.
If it is already unlocked then the drive/stepper motor or belt is bad.

Unit makes a clicking sound at end of the power-up sequence


Sounds like the scanning mirror might be locked - during shipping, the mirror is locked to prevent damage. Look around the back or the underside of the unit and look for a slider with a lock/unlock picture on it. Slide it to unlock and the mirror should be free to move.

Scanner makes a horrible noise until it goes into error state


Sounds like the scanner portion of your all-in-one is bad, best thing to do if its still under warranty is to call HP Tech Support and have them verify the issue: 800-474-6836

If its not under warranty then the machine is done.

The scanner is locked. You need to see the user manual and look for the scanner lock. It just needs to be switched to unlock.

Trouble shooting


The "car sound" could be an indication that the scanner is locked. Check the lock switch on the bottom of the scanner. Move the switch back and forth a few times and then leave it in the locked position. Another possibility is that you are scanning heavy items such as books. If too much weight is placed on the scanner glass, then pressure could be enough to prevent the scanning element from moving as it should.

The code 201 sometimes can indicate a power issue...meaning the scanner is not getting enough power. Try connecting the usb cable to a different port on the computer (preferrably directly to the computer and not through a USB hub).

Unlock


Most scanners shipped have a lock on them to prevent the top from opening up and damaging the glass. This is a screw type mabey other but a penny fits in mine. This may not be the case for you but look in your manual to find the unlock device.
This will also in some scanners prevent the stepper motor from moving in transit . The stepper motor is the device thats makes the bar slide up and down to scan the page.
Hope this helped some.

Hi, when you lift the cover where the flatbed glass is can you see the scanner trying to move back and forth? Also you might want to check and make sure the scanner lock didn't get moved to where the scanner just goes back in forth ? Are you getting any error codes?
