A small piece of foil fell into my printer. When i tried to get it out it went further in. I cannot use the printer because of paper jams due to the foil being stuck inside. Should I take apart the printer myself and try to get it out. What do you suggest? The foil is stuck in between the "gears" that pull the paper through the printer. Thank you.

This problem bugged me for months! Selecting CONT. PRINTING as indicated by Small6363 allowed to print with the warning light on but did not solve the warning light problem. I eventually found a way to bypass the flashing light and warning message.
Underneath the cartridge, on the cylindrical portion, in the middle there is a small flat rectangle. This is the ink level detection spot. Cut a piece of aluminum foil of the same size and place it with a piece of scotch tape overt that flat rectangle. Voilà! No more flashing red light and no more out of toner message! Of course you have to monitor your level visually and change the cartridge when printing starts to fade.
The printer head has locked itself and won't move. I have found a solution for you on the Internet - here are the details :-
I was able to unlock the print head - just with a small piece of foil. Cut
a 3-5cm wide stripe from a sheet of overhead-foil (90um thickness),
move it below the print head, and move it to the front and upwards, to
the back and upwards. Remove the foil. After switching the printer on -
it will work as before and be able to move the head. No need to
disassemble the whole MX700!
The 511 error relates to the PCU rotation sensor. There are several causes and solutions.
1. Toner build up on PCU foil square
2. Toner powder build up on sensor
3. Misalignment of PCU band
4. Damaged PCU foil square.
Solutions1. Toner build up on PCU foil square
Remove PCU from printer and carefully rotate the PCU band around until you see a silver foil square. Remove any excess toner from foil square. Inspect condition of foil square, if damaged go to solution 4. Reinsert PCU and test.
note: PCU band is best described as a black rubber-band type looking material that rotates around the PCU. Be careful not to touch it with fingers or expose to bright light as this can damage it. Clean foil with simple tissue cloth or similar.
2. Toner powder build up on sensor.
Remove PCU unit and using a vacuum and/or can of compressed air spray/**** off excess toner powder from sensor inside of printer. The powder can block the sensors ability to sense the foil square, giving you the error.
Note: Sensor is hard to find, but looking at the foil square on PCU band you should be able to judge by line of sight the approximate location, you are looking for a box with a small tab wire with 2 wires coming out from it. Spray / vacuum in that area. Make sure printer is unplugged be careful not to create a excess of static electricity with the vacuum.
3. Misalignment of PCU band
If your PCU band has moved off to the right or left of the roller, it will need to be realigned. A simple check of the right and left position on the roller will determine if you need to realign. To realign take apart PCU and carefully manipulate into correct position.
Wear gloves and expect this to be messy with toner. Try not handle PCU band excessively as once it is damaged print quality will be ruined and PCU will need to be replaced.
4. Damaged PCU foil square.If the square is damaged, replace with a piece of tin foil. Superglue on carefully.
You don't need to put the new square in exactly the same place, just above or below on the belt is fine.
(Wear a professional n95 mask and rubber gloves). Use a straight razor and scrape off as much foil as possible. Get a hold of Mercuric or sulfuric acid. BE CAREFUL not to spill anywhere, work close to a stainless steal sink. Poor a little in a small glass container and bring over stove porcelain surface. Pour the acid onto the foil and wait 3-4 minutes, use paper towel to wipe off the acid, and then a soapy wet rag. Repeat process until all foil is dissolved. Then wash surface thoroughly and repeatedly with a soapy dish towel. Once complete run water in the sink for 5 minutes till any possible remaining accid is flushed from the sink. The foil is gone and the porcelain is preserved. Works great! (Don't breathe the fumes and ventelate the area or move the stove outside)
Use "The Works Toilet Bowl Cleaner" to dissolve the foil.*Caution* when the cleaner is applied to the foil a chemical reaction occurs releasing some harmful fumes so please use outside or in a well ventilated area.I just did this to a Frigidaire oven I bought from Lowes at a discounted price.The previous owners bought it, did not read the owners manual or just disregarded the warnings on using foil in the oven and thought they would line the bottom pan with foil to help make it easier to clean (Good idea, but don't try it on the hidden element ovens).With the heating element being hidden under the drip pan the heat is hot enough to melt the foil and fuse it to the pan.Now most of the pans on these ovens are removable by just a couple of screws and I strongly recommend removing the pan when doing this.Squirt some Works toilet bowl cleaner on it in a well ventilated area and watch it go to work.It took about 15 minutes for it to dissolve all the foil on my oven, then I rinsed it clean and reinstalled it in the oven.The pan does have a slight discoloration on it, not from the cleaner but from the foil being melted onto the pan, if you choose you can buff this out.Most of the modern ovens have the ceramic coated drip pans in them so the Works toilet bowl cleaner will not harm them, unless you have scratched the finish off.Works Toilet bowl cleaner contains a fair amount of hydrochloric acid which is what makes this work so well.
