HP CP1514N rear door sensor

[Copy link]

Post time: 2015-7-12 16:55:55 |Show all posts
Can anyone tell me where the rear door sensor is a on an HP CP1514N.... the printer is giving a constant "rear door open" error and I suspect either a switch/sensor problem, or a mis-alignment of something mechanically. Either way, I can't seem to find where the problem is - nor can I locate the actual sensor(s) that are used to determine the state of this door!
Thanks,
Robert

The sensor itself is on the HVPS PCB. The actuator that the white plastic peg operates could be your problem. I've had 2 of these give me the same problem you are having just in the last week on a 1415 which uses the same rear door safety switch.

Assuming the white plastic thingy isn't broken, I would first try the switch. I don't know how to access it, since I've never had to. It could be as simple as removing the left side panel and hope that it is visible without removing any other parts as that is not a fun printer to work on. I'm currently out of town, so I can't look at my printer. This service manual should be close enough to your model, I hope.

Thanks for the information.
I have two printers here of the same model. On the one without the problem, I can (as you describe so clearly moe) poke something in and convince the printer the rear door is shut.
On the one WITH the problem, this does not work.
So my next questions are:
Which is most likely to fail; the switch itself, or the wiring/connector ON the switch? Could it just be a loose connector?
Any suggestions as to how to approach this? (How best to get the switch out or get to the wiring?)
It's frustrating having a fully functional printer unable to be used because of something so seemingly trivial...
Thanks,
Robert

I've got a CP1518 I just played with, should be the same design. If you open the door and look at the right side of the assembly mounted on it, you will see a white plastic thingy. There is a small plastic peg that sticks out at the top. That goes into a slot and pushes on a switch. I was able to poke something in there and it made the printer go to ready.
