Printing double-sided when paper jammed badly. Every piece of paper has been removed, even the roller dismantled but screen still showing paper jam. The machine is a LaserBase MF5700.

Hi,

Please clear out the paper jam by removing the tray and removing any pieces of paper stuck in the printer. You can also open up the back of the printer and remove paper as well. Then, try to print on both-sides again. If your printer has multiple trays, try switching the source tray prior to printing.

Thank you.

check between the rollers there will be small bits of paper jammed in that is the reason.

It appears to be known problem and the fix is to replace the pickup roller. The problem as you noticed is that it has dried out.

Internal paper jams on this machine tend to be in the two-sided printing accessory.

To clear a paper jam from the two-sided printing accessory:
1. Turn off the printer
2. Press in the tabs on the left and right side of the two-sided printing accessory, and remove it by pulling out from the center of the printer.
3. Gently pull the paper out of the rollers. If the paper has torn, check the rollers and wheels for small, torn pieces of paper
4. If it's still not clear, open the two-sided printing accessory by pulling up on the tabs, and remove any paper stuck inside it, then close the accessory by pressing down on the tabs until they lock into place
5. Replace the two-sided printing accessory by pushing it forward until it snaps back into place
6. Turn on the printer, and verify that it works by pushing OK to continue the job it jammed on.

this will be an issue with the duplex rollers check where it is jamming is it in the duplex unit if yes then check the duplex rollers for wear worn rollers will cause scews also check there is no torn pieces of paper stuck in the guides of the duplex
a good thing to do is to get a thin piece of card stock slide it into the duplex manually and frred it where the paper path goes on the duplex from beginning to end and it will push out any thing in the path

make sure you don't have any small pieces of paper stuck in the printer
Paper jams can be real or false. The unit may report a paper jam when there is not any jammed paper, however, the solution to a real paper jam or a false paper jam is the same. WARNING: Jammed paper must be removed using the rear access door and the power cord must be disconnected or a carriage jam or mechanical damage may occur. Do not remove jammed paper from the front of the unit.

1. Turn off the HP product and turn it so the back of the unit faces you.
2. Disconnect the power cord from the back of the all-in-one. The power cord must be disconnected to allow the paper feed rollers to turn freely.
3. Locate and open the rear access door by pressing in on the left side tab and then pulling the door toward you. Figure 1: Removing the 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.
4. 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.

5. From the rear access door opening, remove the jammed paper.
6. 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.
7. Reinstall the rear access door.
8. Reconnect the power cord to the unit and turn the unit on. If a carriage stall occurs after clearing the paper jam, resolve the carriage stall.

You may have to reach through the output paper tray to access the print carriage.

Step six: Service the printer
If you have completed all the steps listed above and are still experiencing a problem, service the product.

Hi

Thanks for using FixYa. Perform the steps below in order to solve this incidence:

1. Disconnect the power cord or power supply adaptor from the rear of the HP All-in-One product.
2. Remove the paper pack remaining in the input tray.

WARNING - Do not try to remove the jammed paper sheet yet. Trying to clear a paper jam from the front of the device can damage the print mechanism. Always clear paper jams through the rear access door.

1. Open the rear access door or the two-sided printing accessory.
2. Gently pull the jammed paper sheet out of the rollers.
3. If the paper tore when it was being removed from the rollers, check the rollers and wheels for torn pieces of paper that might remain inside the device. If not all the pieces of paper are removed from the device, paper jams are likely to occur again later.
4. Replace the rear access door or the two-sided printing accessory.
5. Restart the printer to continue the current job.

Can be tricky people usally damage the fuser rollers removing this jam with pliers/tweezers, it has concertined and stuck after fuser rollers and before exit rollers it will be stuck on the switch best bet is to dismantle properly and remove fuser then dismantle fuser and remove jam, another thing to be concerned about is why did it, three seneraros, Damp paper going threw fuser dries and crincles(use fresh paper from sealed packet), fuser is worn(have fuser replaced), just a bad bit of paper (just have fuser jam removed. Fusrr runs on 240v, covers break easy
