 | Dell Laser MFP 1600n constant paper jam by ANNAM (2/15/07 5:12 AM) reply | + / - | Hi folks
I've got a dell laser MFP 1600n and for the last couple of days the paper constantly jams. The readout says it's a 'Jam 1' which I think means it's a paper exit jam. I've tried shaking it, pushing card through it, using different paper all to no avail.
Anyone have any ideas?
Thanks

 | Re: Dell Laser MFP 1600n constant paper jam by Anonymous (3/9/07 6:11 AM) reply | + / - | Read this on dell's forum (less than 5 minutes):
I just went through the trouble shooting with Dell the other night. They offered to fix it but its actually simple pretty to fix yourself if you are at all mechanically inclined.
I'll do my best to explain the fix. First, verify that there is actually no paper jam (open all the doors, take out the paper tray, take out the toner/drum unit and visually inspect),
If none, chances are there is a little plastic piece inside the printer that has popped out. The little piece allows the printer to detect when a sheet is exiting the printer. When it pops out, its gives the printer a false reading which makes the printer think there is a paper jam.
So, onto the fix. Turn printer off and unplug the printer from all cables (power, USB, phone, RJ45, etc). Secondly, take out the drum/toner unit and place in a dark spot like a closet.
Next, with the back of the printer facing you, turn the printer over so that it is resting on its front. The bottom should be facing you, and the back of the unit should be pointing towards the ceiling. I will use this orientation when describing the following steps.
Most of the back of the printer is actually a removable piece held in place by 4 silver cross head screws. Two are near the bottom of the printer in fairly deep recesses. The top two are easily accessible. Using a regular cross head (not flat head) screw driver, remove the 4 screws.
Once removed, the entire back panel should lift right off. You will then see the inside of the printer. You are looking for a small, gray plastic piece with a spring attached to it. It will probably be loose in the back of the printer. Its approximately 1.5" long and is roughly S-shaped. One end is different then the other, with one end being relatively skinny and the other end having a sort of paddle shape.
This is the piece that has popped out and makes the printer think there is always a paper jam. If this piece is not loose and is properly secured in place then you have a different problem. Reassemble the printer and call Dell for a replacement printer.
If the piece is loose, pick it up but ground yourself to the printer by touching any metal in the printer. Try not to touch the various electronics inside the printer unnecessarily.
Looking at the back of the printer, roughly in the middle where the paper exits is a black bar with various rollers on it. Below this should be a piece of sheet metal, gray in color, running from once side to the other (left to right) of the printer.
Visually follow this sheet metal piece. Roughly in the middle (left to right again) should be a small rectangular opening. Immediately below this should be a little black plastic piece with two little arms sticking out towards you, with a third arm perpendicular to the first two. This piece will be mounted on a small beige/brown PCB.
This is the actual sensor that the gray S-piece popped out of. If you look at the gray S-piece, you will notice that it has two little round knobs, one sticking out on each side. These knobs snap into the small semi-circular feature on the top of the two arms. The third arm is where the spring on the S-piece pushes against.
So, take the gray S-piece and hold it so that the spring is on the left, the thick paddle part is pointing towards the bottom of the printer, and the skinny part is pointing towards the top of the printer (towards the scanner section).
The skinny curved section of the gray S-Piece actually hooks behind the black roller. Thread the skinny curved section of the S-piece through the rectangular opening in the sheet metal piece and hook it behind the black roller.
Next, locate the two knobs on gray s-piece with the arms on the sensor so that they align with the top of the arms. Ensure that the spring's free arm is also lined up with the third arm on the sensor. When lined up, push down with a a small amount of force. You feel/hear a faint snap as the piece clips onto place.
Check that the spring is properly located in its arm by pushing against S-piece to make it rotate. When you let go, it should spring back to its default position.
That's it! Reassemble the back cover using the 4 screws. Go finger-tight only. These screws are only tapping into the plastic so if you over-torque them you will strip the holes.
It sounds tedious, but it took about 5 minutes to fix and now the printer is working fine.

It seems though that the top of the gray S piece is broken in half. Does anyone know what part number this piece is and where I can order it from?

Call Dell Service and tell them that the rear paper sensor arm (gray S-shaped piece attached to middle of metal support bracket on the fuser--it obstructs the jam sensor when paper is rolling through) has broken. They will be able to tell you if you can order a new sensor arm or whether you must order the entire fuser assembly.

How do you find out what the # 2 means?

| Re: Dell Laser MFP 1600n constant paper jam by jkainen (2/6/09 9:58 AM) reply | + / - | Intermittently, I get [Paper Jam 0] Open/Close Door error when trying to print. When it happens, sometimes just opeing and closing the door does the trick. Other times, it just keeps happening until the door is pen and closed many, many times. Once it starts to work, a 50 page document will print with no further errors. Other times, it will happen on every page. I've tried looking at the "S" piece after opening the back, and that is not the problem. Anyone have a fix?

May someone come into my rescue,I need to fix this by myself.

| Re: Dell Laser MFP 1600n constant paper jam by pnutjam (3/23/09 8:46 PM) reply | + / - | I have been having the same problem. I almost gave up on this printer. After careful analysis I noticed that if I pulled up on the cartridge while it was inserted and held it up (I took the door off and depressed the door closed button w/ a screwdriver) the printer would work fine.
I shimmed the front of the cartridge w/ a piece of rubber or folded up paper. There appears to be something in the back that doesn't make full contact if you do not do this. Now it works fine.
I haven't had any feed problems, but I kept my shim to the front right and made sure it doesn't go too deep.

It's exactly what happened and by following the clear procedure written, I've fixed mine in less than 3 minutes ( 6 minutes total including reading).

can you be specific about how and where to put a piece of wadded up paper or whatever to keep the cartridge tight? I think that may be my issue, but I am not sure where to put it or how...

| Re: Dell Laser MFP 1600n constant paper jam by MikeF in SF (10/5/09 10:25 AM) reply | + / - | It totally worked for me. Once you open up the back as described, It is easy to see the gray piece of plastic and see that it just popped out.
Thanks! and the landfill thanks you too!!
