On page 199 it does not show how to disengage the pick assembly, and nothing I've tried disengages it. It feels like it will break, so I am not forcing it. However, my documents are streaking at the farther edges, like approximately 1 inch (2.54 cm) from each edge, so I'm not confident that cleaning that portion of the scanner will resolve the problem..

Re: HP 7410 streaks on scanning and copying
First you need to determine if it's doing from both the top and the glass.
1-assuming you are using the feeder to fax,copy or scan (the part that automatically picks up the paper) it comes out with a streak. Make a copy putting the paper on the glass and look at the copy. Does it have the streak?
2-lift the top and look to the left there should be a small 1inch glass, this is where it makes the copies from the feeder, is there a dot or white out or is the glass dirty? that's your streak, the paper is moving to make the copy,so the dot now looks like a line as opposed to making a copy on the glass it just sits there so a dot will stay a dot.

those switches make continuity ( makes the circuit to the brake light ) when we brake our vehicle, then when brake pedal is not being pushed it disengages the circuit, therefore turning off break lights.
Use an ohmeter with no voltage applied to ciruit , check switch With switch engaged ( zero or about zero ohms ), switch disengaged should show infinity ( nothing on the ohmeter ).
If the blade brake is engaged, it can be extremely hard to disengage when not mounted on the saw, as I'm sure you already know. One thing you can try is loosely mounting the cover on the bar studs with no sprocket installed so that you will have the leverage you need to disengage the brake band. Good luck.
This means a printer motor error has occured. From the service manual: C developing disengaging motor rotation error.
Developing disengaging motor error 1 Reconnect the connectors J16 for the developing disengaging motor and J1100 for the DC controller PCB. 2 Replace the developing disengaging drive assembly. 3 Replace the DC controller PCB. Calibrate the printer after replacing the DC controller.
So, at the very least you'll need the developing disengaging drive assembly and, if that doesn't fix it, then you'll need the DC controller board. My bet is the DC controller has failed.
Sorry for the bad news, but please rate this solution as fixya even if it wasn't what you wanted to hear. Thanks.
sounds like your brake cable has broken or there is something damaged in the pedal assembly.........try pulling on the release handle and move the e-brake pedal back to its off position by hand at the same time.(you may have to tie it in this position to keep it up)If that doesnt work there is a sensor on the pedal assembly that you should be able to bypass by either disconecting the wire(1 wire system) or connecting the two wires together (2 wire system)Especially if your truck is a standard the e-brake is an important safety feature,so if these steps fix the light and dinging problem you should still take the steps to have it repaired.
hope this helps.........Good Luck!
