Huge gear grinding noise

[cqian45]

Dear friends,

I need some help with fixing my HP Laser jet Printer P1102W please! (See picture 1)

Picture 1

Last week I inserted a thicker paper. The machine didn’t print. All of a sudden, it started a huge loud gear grinding noise, at around the rear right bottom part (See Picture 2). I stopped running the printer at once.

Today I am trying to disassemble and fix it (See Picture 3 and 4). I admit I am not handy, but overly confident. I thought it would be easier, but I am so wrong. I am having troubles now.

----> Trouble 1: I find there are two gears (white on top and black at bottom) (See Picture 5, the black gear is right beneath the white one, of same size, but hard to see in this pic).

Right now, the white one is stuck and not spinning, but the black one is free to spin. I am assuming the white stuck gear is the reason for the huge grinding noise? Am I correct? How can I make it spin? It is very stuck tight there!

----> Trouble 2: I accidentally touched one of the springs on the shaft which is attached to the gear, and the spring fell off. (See Picture 6, Spring B, now its one end is hung freely in the air) I am not sure how to put it back properly right now. Can someone show me how I can place it back please?

I would really appreciate it if any kind handy professional tech guy can help me with fixing my printer!! Please let me know. 

Thank you!!

You will need to remove the pick up assembly, base model RM1-6880-000CN; wirelesss model RM1-6915-000CN.  Spring just pooped off.  Easy fix.  It is attached to a sensor flag.  Just use the good spring as a guide.  Good luck.
