The problem is that the motor that drives the scanner probably overheated and because of the cheap plastic that HP used it melted important points that the motor relis on...so - remove the glas of the scanner(there are some screws - one of them hidden under the label of the panel,unhook the interface cable of the panel).Now you should see the scanner - flip it over and look at the motor exle and the gear that it should mesh with - they are not aligned at this time.To fix it i used 2 small pieces of plastic - sticked it under the motor so that it can not move in vertical direction anymore. Simply this is the solution that i used and it works just fine :) If you have any questions dont hesitate to contact me. [email protected]
