Paper Jams and Margin Incorrect

The official HP website page for trouble shooting the printers HP OfficeJet Pro X series - Resolve paper jams including "Print Zone" jams ' HP® Customer Support

Is that true for both print and copy job ?
Where does the jam happen ?

I am thinking if it is at the paper pickup roller area just as the job starts to print and not midway while printing, check the paper quality; dirty pickup roller; clean cork pad and try job from another tray

Here is some tips to avoid paper jam..

• If your printer has a paper tray do not fill the tray to capacity. If you're encountering frequent paper jams, reduce the amount of paper you place in the tray each time it is filled.

• Make sure you or the tray feeding the paper into the printer is aligned properly and the slider used to hold the paper in place in the tray is snug with the paper. Many printers have sliders that allow different types and sizes of paper to be fed into the printer. If the slider is not properly positioned it can cause paper jams.

• Use standard office paper; folded paper, paper with labels, and specialty paper such as hard bound paper can often cause paper jams. If you're uncertain with what paper you should use with your printer your printer documentation will list the paper compatible with your printer.

• Do not mix the paper you're feeding into the printer at one time. If you need to change the paper or size of paper being used removed any other paper currently in the printer before inserting the new paper.

• If your printer uses a slot or tray for the paper make sure to not push the paper too far into the slot or tray.

• Examine the printer for any previous stuck paper in the printer. Previous paper jams, torn paper, printing labels or other foreign objects in the printer can cause reoccurring printer jams.

It's been a while since I worked on a 4200. Will it print if you keep the back door open?
If yes, does it jam?
If yes, and it doesn't jam, replace the paper delivery assembly(RM1-0026-040CN)

still printing but the paper goes no further?. It may be the paper is locked by paper feeder mecahnics, Open case, check it, and may be there is something "material" broke.

make sure the paper is not bent cuz that happened to me and i flattened the paper and it worked fine.

Often the paper jam light will stay on when the *back* paper jam door is not cleared.

Open up the back of your printer. There is a 2nd door behind this door that you can pull open. If there is a paper in this section, pull it out and it should clear your red light.

When clearing paper jams, clear the front first, and then if the red light is still on, you need to check the back hidden door for another piece of paper.

this is probably the sensor inside the transfer sheet or the reflection plate under the cleaning blade assy being dirty. also there is a reflection plate on the bottom of the transfer sheet near the gear assy

Clearing paper jams Paper jams can occur for a variety of reasons but are usually paper related. Follow the steps below to clear the paper jam:

1. Turn off the all-in-one and unplug the power cord. With the power off, the paper feed rollers will turn.
2. Open the rear access door of the all-in-one by pressing in on the left side of the access door and then pulling it toward you. NOTE: All paper jams must be removed by pulling the paper out the back of the all-in-one using the rear access door. Pulling the paper out the front of the all-in-one rotates the paper feed rollers in the wrong direction and can lead to additional problems. Figure 1: Rear access door Inspect the pressure rollers on the rear access door and verify that they are clean and turn freely. Clean the rollers if needed with a soft towel lightly moistened with water. If the rollers do not turn freely, replace the rear access door.

3. From the rear access door opening, gently pull the jammed paper free.
4. Remove the remaining paper from the paper supply tray. Discard any paper that is damaged or crumpled and then re-stack and reload the paper into the paper supply tray. Do not continue to push the paper in after some resistance is felt. If the paper is pushed in too far, more than one page will feed into the all-in-one at a time.
5. Reattach the rear access door by inserting the two pins on the right of the door into the holes for them (as shown in Figure 3 below) and then pressing in gently but firmly on the left side. Figure 2: Inserting the rear access door guide pins into the holes
6. Reconnect the power cord to the unit and turn the unit on.
