Hi there,

Here is the most important thing to understand about paper jams in any printer....

The printer does not know if there is a paper jam anywhere in the printer.

What it does do, is respond to sensors ( optical sensors, either open or closed, by plastic flags). These flags are moved as paper moves through the paper path.

One example of a paper jam message when there is really no paper jam, is when the feed rollers are worn and do not pick up paper from the paper tray.

When you start printing, the printer expects that first sensor to open ( paper passes the sensor ) at a very specific point in time. If the paper did not get picked up from the tray, then the printer will ASSUME that the paper must be jammed somewhere because it did not reach it on time.

Now this will also happen if in fact the paper did get picked up and then jams prior to the sensor.

So... if you get the picture of how this works, understand then too, that if the printer is showing a paper jam message at power on, then one of the flags is open when it should be closed.

If you do not actually have a piece of paper holding this flag in the open position, then the flag is possible broken.

I usually see this kind of damage occur after a true paper jam, where the paper is removed either in the wrong direction ( pulled out back the way it was going instead of the way it should normally travel ), and this breaks the flag, or it was pulled out forcefully again, catching on and damaging the flag.

All of the above pertains to ANY printer, and not just yours. you must take care to fully inspect every inch of the paper path, from the paper tray, to the exit, use a flashlight, and look for the sensors and make sure they are not blocked or broken.

Good luck,

Cory

Here's what you do. Take a look at the photo below.
Open the cover of the printer, where the ink cartridges are located. Behind the ink cartridges is the carriage, which is a box that moves side-to-side on a pair of rails. It's the thing that sprays the ink onto the paper.

You have to reach in with your hand and slide this thing to the center. Then, look to the very sides, left and right, for any bits of paper. If you look at the second picture, you can see my finger pointing to a small bit of paper that tore of and got jammed into the side. See the little crumpled bit of paper? It's preventing the carriage from sliding all the way to the right. You could have little bits on the right or left side. I had to reach in with needle-nose pliers to grab the paper bits out, but maybe your fingers are small enough.

Once the little bits of paper were out, I was back in business. Good luck!

Please try this to clear the paper jam

1. Turn off the printer.
2. Remove any paper trays. Inspect them for wrinkled or damaged paper.
3. Also open the back cover of the printer if this model has one.
4. Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
5. If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
6. If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
7. If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do this step especially if the jam message comes up repeatedly without any obvious paper jam, there may be a small tear of paper inside.
8. Ones the printer is free of paper Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
9. If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
10. see alternative if the problem is still not solved.

I had the same problem. I called HP and went through the steps they had asked me to go through to fix it. It took about an hour. Nothing worked. They offered me a replacement. I said no, and they offered me a $150 gift card for Staples.
