IT IS GIVING ME CLEAR MISFEED (A) I DID THAT AND IT STILL TELLS ME TO CLEAR MISFEED, I EVEN TURNED AND UNPLUGGED IT AND CLEARED AND CLEANED AND STILL HAS THAT MESSAGE

4. Exit sensor it is in fuser unite.
May be any sensor displace or broken.So you should check it.
Good luck.

The MISFEED Indicator blinks when a MISFEED has occurred. Remove the misfed paper referring to the the description of MISFEED REMOVAL beginning on page 65 of the pdf Manual at:

http://files.sharpusa.com/Downloads/ForHome/HomeOffice/PrintersFaxMachines/Manuals/cop_man_AL2030_AL2040CS.pdf

When the MISFEED Indicator is blinking you should look closer at the paper feed area (see page 66 of the PDF). You may need to remove the paper tray to find any remnants of paper. If after closing the side cover the light does not stop blinking you will need to follow through as per the illustrated instructions.

Remember after removing jammed paper, you need to press the clear key to clear the MISFEED error.

If after doing all this the error signal has not cleared, power down the printer; unplug from the power supply; let rest 5 - 10 minutes; plug back i to power supply; turn printer on and see if this resolves issue.

It calculator tells you Ram Cleared each time you turn it on, the most likely reason is that the backup battery is depleted. Its role is to keep the memory modules electrically refreshed when calculator is turned off. If the backup battery is dead, the memory is erased when you turn calculator OFF. Main batteries no longer supply power and the contents of the memory are cleared.

1. Check that main batteries are good and inserted in calculator.
2. Turn calculator OFF.
   
3. Replace the backup battery.
4. Turn calculator ON.
5. Press the [CLEAR] key to erase the "Ram Cleared" message.
   

Clean the sensors in this parts and try reset the SC codes:Enter in the SP mode press 5-810 (SC code reset)select 1.Then hold down the Photo mode key and the +key at the same time for at least 4 sec.

have you tried turning of the power and unplugging ALL cables including telephone line . leave for 1 min then recconnect and try again. Or could be a very small piece of paper as a little near the sensor will confusew the machine

there are little plastic fingers on the drum and heating rollers (hot), one of those is raised up from the surfaces of either component, causing your paper to catch. both move back and forth on tiny springs. on the fuser you can actually remove several of these fingers if they are the problem and still use. on the drum they must be repositioned or replaced

Micro switch is sticking or damaged. the Yeti

some machines will want all covers to be opened, then closed, for good reset. if you are having jams in the adf, then open all adf covers, and lift the adf upward, if it allows. also, try turning unit off, then back on. some jams only clear that way.

Look for little pieces of paper that get stuck in the rollers, also verify that the gears and roller didn't get misaligned when you cleared the jam.
Good Luck, 

DEAR SIR WHERE YOU REMOVE THE PAPER IN THE MACHINE THAT SECTION THERE IS PAPER PATH SENSOR ,THAT SENSOR POSITION IS ABNORMAL PLEASE CHECK THE SENSOR OF THAT SECTION WHERE YOU REMOVED THE PAPER
