Dell Printer 1720

Sir/Madam

Occasionally, media becomes jammed during a print job. An error in the software program and a jam message on the printer control panel display indicate a media jam. To prevent a jam, see the following instructions:

• Only print on media that meets HP specifications.
• Only print on media that is not wrinkled, folded, or damaged.
• Make sure that the printer is clean.
• Make sure that the input trays are loaded properly and are not too full. See the start guide for more information about loading input trays.

When adding new media, always remove all of the media from the input tray and straighten the stack of new media. This helps prevent multiple sheets of media from feeding through the printer at one time, which reduces media jams

Clearing a media jam

CAUTION: Media jams might result in loose toner on the page. Use cold water to wash toner off of clothes, as hot water will permanently set the toner into fabric. To remove toner from hands, wash hands in cold water.
CAUTION: Do not use a sharp object, such as a pencil or scissors, to remove jammed media.
NOTE: When clearing jams, including jams in the output bin, always push the print-cartridge-door release to open the top cover, and remove the print cartridge. Keep the top cover open and the cartridge out until the jam has been cleared. Opening the top cover and removing the print cartridge relieves tension on the printer rollers, which makes removing jammed pages easier.


Push the print-cartridge-door release and open the top cover.
Figure 1: Pushing release and opening top cover



Grasp the handle of the print cartridge and remove it. Set it aside.
Figure 2: Removing print cartridge




CAUTION: To prevent damage to the print cartridge, do not expose it to light any longer than necessary. Place the print cartridge in a paper bag or other opaque container until it can be placed back in the printer.

With both hands, grasp the side of the media that is most visible (this includes the middle), and carefully pull it free from the device.
Figure 3: Jammed media most visible




When the jammed media is removed from this area, replace the print cartridge.
Figure 4: Replacing printer cartridge



Press the supporting springs, and close the top cover.
Open the media input tray and remove any media from the tray.


Slide the media guides inward as far as they will go. Press and hold down the tabs inside the media input tray, and slide the media input tray out of the printer.

With both hands, grasp the side of the media that is most visible (this includes the middle), and carefully pull it free from the device.
Replace the input tray into the device.
Figure 7: Replacing input tray




After clearing the media jam, it may be necessary to shut down the printer, and then turn it on again.

NOTE: To add new media, remove all of the media from the input tray, straighten the stack of media after adding the new media, and then place the stack in the tray.
Clearing other media jams
CAUTION: Do not use a sharp object, such as a pencil or scissors, to remove jammed media.
If the media has jammed where it exits the printer, grasp the leading edge of the media and pull the media out through the output bin.
Figure 8: Removing jammed media from output bin




NOTE: If the printer is shut off before clearing the media jam, turn it on again, and then restart the printing or copying job.
Tips to avoid media jams
Make sure the automatic document feeder (ADF) media lever is in the correct position for the media being used. Slide it to the single-sheet setting (to the right) when scanning on thick media. Slide it to the multiple-sheet setting (to the left) when scanning on regular media.
Make sure that the input tray is not overfilled. The input tray capacity varies depending on the type of print media that is used.
Check that the input tray is securely in place.
Do not add print media into the input tray while the printer is printing.
Use only HP-recommended media types.
Do not let print media stack up in the output bin. The print media type and the amount of toner used affect the output bin capacity.
Check the power connection. Make sure that the power cord is firmly connected to both the device and the power supply box. Plug the power cord into a grounded AC power outlet.
Media jams occur in the automatic document feeder (ADF)

Occasionally, media becomes jammed during a copy, scan, or fax job.

A software error message indicates a media jam, and the Doc feeder jam Clear, Reload message appears on the printer control panel display to indicate a jam.

• The ADF input tray is loaded incorrectly or is too full.
• The media does not meet HP specifications.

Typical automatic document feeder (ADF) jam locations Input tray areas: If the page is sticking out of the input tray, try to remove it gently from the input tray without tearing the page.
Figure 9: Removing jammed media from input tray




Output paths: If the page is sticking out of the output bin, try to remove it gently without tearing the page.
Figure 10: Removing jammed media from output bin

• Intermediate location: If the page is sticking out of the input tray and into the output area, see "To clear a media jam from the automatic document feeder (ADF)" below for instructions.

Automatic document feeder (ADF) media lever If a thick media is being used, slide the media lever to the single-sheet setting (to the right). Load a single sheet of media into the ADF.
When the copying, scanning, or faxing jobs are complete, slide the ADF media lever back to the multiple-sheet setting (to the left).

1. Remove any jammed media. Figure 12: Removing media
   

NOTE: Use only your hands to remove jammed media. Using other objects can damage internal parts.
Make sure that all of the pieces of media are removed, and then close the printer control panel door.

On the top where the paper comes out is a sensor. There is a flap with an arm attached that passes thru a photo-sensor. make sure the flap is not stuck in the up position and make sure the little arm is not broke off. You will need look very closely

If the lamp is on solid that is a cancel job or reset printer indicator
If the lamp is blinking (flashing) that is the secondary Jam error meaning somewhere in the paper path is a jam. The lamp shoul dbe blinking in a sequense - that sequence indicates what are of the printer the jam is. So the lamp should blink a number of times, pause then blink the same number again.

1 blink - jam in feeder sensor
2 blink - jam in manual feed
3 blink - jam under toner
4 blink - jam in output are
5 blink - jam in tray 1
6 blink - jam in tray 2 (if present/option)

Please try this

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.
    

alternative :
Load a piece of thick paper, for example photo paper and press the resume button (may be diffrent button on diffrent models) a few times to the printer picks up the paper and puts it through the machine.

It might be the tray Feeder not placed properly or the printer needs a service if not done in the last six months. Contact to your nearby Repair shop and Service centre.

Step1
Turn the printer off and on to see if it can automatically clear some or all of the jam. Many printers provide an error-code listing on the front panel display for the area where the jam occurred. If your printer shows an error code, be sure and check the printer manual to see if that identifies the area of the printer where the jam occurred.
