I have an HP Scanjet 5P scanner that had a yellow vertical streak the entire length of the scan bed. I found out how to remove the cover and remove the mirrors. There was some discoloration on one of the mirrors, so I cleaned it and replaced it.
The problem I have now is when it makes a scan, the head scans all the way to the bottom of the scan bed and then gets stuck there and won't return to the home position. I went to HP's website looking for answers and found none!!! I tried what they said to "re-home" it, and it did not work. It is still stuck in the bottom of the scan bed. Scan comes out totally black and makes noise. I tried disconnecting it from the power supply, still the same problem.
All help and suggestions would be greatly appreciated.
