The drum doors were not closed properly and now one is jammed, I cant see it. How do I get to the other side of the drum to return the door to the flat surface of the drum

Error codes 501, 502, and 503 on a Ricoh MP-8001 indicate a problem with the paper cassettes. SC441 is a drum motor error code. Here are some steps you can take to troubleshoot these issues:

1. Check the paper cassettes: Make sure that the paper cassettes are properly loaded and that the paper is not jammed. Check that the paper guides are set correctly for the paper size.
2. Reset the paper cassettes: Open the paper cassettes, remove the paper, and then close the cassettes again. This may reset the paper cassette sensors.
3. Check the drum motor: SC441 is a drum motor error code. This may indicate a problem with the drum motor or the drum unit itself. Check the drum unit and make sure that it is properly installed.
4. Check the front door sensor: If the front door open sign is appearing on the screen even though the door is closed, there may be a problem with the front door sensor. Check the sensor and make sure that it is properly installed and functioning correctly.

If these steps do not resolve the issue, it may be best to contact a qualified technician for further assistance. They will have the expertise and equipment necessary to diagnose and repair the problem.

SO this is how I fixed mine. There were no broken parts and I dont know if the small plastic part that has one screw holding it on is supposed to move up and down. It doesnt matter how tight the screw is, it wont stay in the upright position. So I turned the priinter upside down and THEN closed the door. Gravity held the plastic part on the back of the door in place and door closed easily.

check the damper vent door for proper opening and closing as if this door is frozen shut or broken and jammed it cant open to let cold air in from freezer it will be behind a plastic grille between the freezer and fridge compartments and you should hear a fan in there running to move cold air too

Hi

For resolving the error first properly check the paper jam bcoz any small paper also make the error see the printer drum side therefore you find any paper then remove that one, second check your printer cartridge ink level if low level then change the cartridge third check the you have properly close the all door of printer....

Hello,
probably the problem is in laser shuter or toner cartridge pin in toner holder. But when you try to copy, when paper goes to the drum, open the right cover and produce paper jam, now look at drum for image, if on drum isnt image its laser problem...

If the laser shuter is faulty, these means that when you close the right door, the nose on door doesn't lift the laser shuter and so the laser unit cant write on drum.

If the toner crg. pin is faulty, when you insert toner in holder inside the copier, on right side of toner holder is small circle with pin that contacts the toner and gives voltage. You can apply some wd40 to that circle, that goes in and out when you open or close door.

But, probably is laser shuter... to check him you need to dismantle the copier.

Hope that helps!

No! There is no switch to reset after a jam.
Make sure that there is no paper in the machine. Example: Finisher, trays, etc...
After that make sure that the doors are properly closed.
If you still have the same message probably you have a broken door switch.
Hope this helps you

YOu can go online and type in the make and model and they should be able to download the instructions for you

Look at the door's locking mechanism. Is the Latch Gate in the down position? Is the Door Mechanism properly tightened to the door? These are Torx/Hex head bolts. Tighten these if needed.
If the Latch Gate is down:
1. Unlock the door.
2. Lift up/out on the Door Handle as if you were opening the door.
3. Use a screwdriver to lift the Latch Gate so it lifts the Gate up and out of the way.
Alot of these Gates have plastic coverings that sometimes split and stick or cause the door mechanism to jam. Inspect the Door Mechanism for anything that could be causing it to jam. Using a pair of needle nose pliers remove any of this split plastic (if so equipped) pulling as much of it off the Latch Gate.
Use WD40 with the red spraying hose on and stick it as many openings you can and lubricate as much of the Door Mechanism as you can.
Check the operations (plural) of the Door Mechanism, Opening and Closing the Gate using the screw driver to push in the Striker Gate causing the Latch Gate to rotate back down into position. Repeat... checking for the Latch Gate to Release Up (on it's own) when you "open" the door. If it doesn't, then there is either jammed or a return spring is broken.
Have you dented or distorted the Door and / or Door Mechanism in the process of trying to slam the door close? You will have to either bend the the door area back to as close to possible the original shape. Use the other door on the other sides as a guide on this. You may have to replace the Door Mechanism itself, as when they are malfunctioning and are slammed (over and over) it could break the Mechanism itself. If the Mechanism is broke, you will have to remove and replace the entire mechanism.
Let me know if this helped, or if you have additional information of questions. Feel free to conatct me at FixYa.com!

what you have to do is make sure door lock is in unlocked position put a flash light inside the door to see you need to get a screwdriver into the release spring area try to pry up on the hook area that flips over the piece thats mounted to the door jam it should release sounds like you need to spray wd or blaster in the lock assembly return spring not kicking back

A technician should look at this. There could be a gear going bad on it. Ive see a fee cases where the drum gets bad and cant turn any more.

Are there error codes on the screen?

Make sure the right door where the bypass tray is closed all the way.
