Sometimes it's better to run the CD or downloaded program again to reset everything.

I am repeatedly getting error code 5010 once I scan any document.


Ok it can be either 2 things: The FIRST is if you have not UNLOCKED the scanner lock switch. The scanner lock switch is a switch that keeps the scanner assembly frozen in place so that when you move your scanner from room to room or apartment to house, the scanner wont freely move around the unit causing it to be dammaged.

To unlock the Scanner lock switch just lift your document cover and look for the swtch on the LEFT hand side of the scanner's glass bed.

SECOND: IF the scanner lock swtich is set at UNLOCK, then your scanner assembly is broken and needs to be replaced. You must then send it to Cannon or any Mulitfunction printer repair place.

I hope this helps you :)

Need to unlock "carriage lock"


Hi caddillacdzn,

Well the carriage lock is indeed at the bottom of a scanner usually. Now personally I don't have this model of HP scanner but I have something similar to that, and this procedure may work for you. Please check this procedure out from the HP website and see if this will work for you:

Hope this helps!

Peace! :)

Scanner locked - unlock scanner


To unlock a scanner open it where you would put cartridges in and look for a red or green colored tab hanging down. There should be a little picture of a padlock. You can switch it from lock to unlock. It's kept locked to protect the scanner during shipping.

Hope this is helpful...

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.
