Sharp AL-1642CS fuser problem

I work for a very small (4-6 employees) company. They have two Sharp Multifunction Printers. One of them, the AL-1642CS, started making a loud intermitent noise. I told my boss that a belt or gear was slipping and they needed to get it fixed before it got worse. It got worse. The noise is basically constant. If you're just printing on the top half of the page, you'll be okay. But it puts a fold in the middle of the page and the bottom half basically doesn't print. I finally convinced them to let me take it home. The noise is the fuser gears. While pricing out a fuser, I learned you can get parts for the fuser itself, and oil. My question is: What, most likely, is causing this? And could the oil solve it? They don't have a lot of money, that's why I'm trying to help. But I could use some help myself. Thanks for your time and assistance.

    I took the fuser apart, cleaned it, lubed it, noise gone. Now I have a paper jam error. Can anyone tell me where the sensor is? I'm figuring I knocked it out of alignment while cleaning.

    Okay, fixed the sensor problem. Now, what I thought was fixed, apparently isn't. I guess the sensor keeps the fuser from turning on. I know it's the gears that are making the sound, but why? It seems that the rollers are too tight against each other, making it hard to turn, which would cause the gears to grind. What would cause the rollers to suddenly be so tight?

Please Help!!!!!

The fuser has a flag sensor with an arm that the paper hits as it passes through. That arm moves a flag at the other end that hits a photointerrupter. You may have broke this. If so, you will likely need to order it through a dealer.

My Sharp Al-1642cs is leaving a black stripe on the paper when coping.

Does the line appear when you copy from the glass? Or is it Just the document feeder. If it is just throught the doc feeder then you have to clean the **** glass next to the main glass. It only takes a small dot to make a line. Hope this helps. Have a nice day.

Sharp copier AL-1642CS

Here is what worked for me.
You need to alternate pressing the clear button then one of the auto buttons until the display lights turn off.

First press the clear button (red letter “C” on the unit) then the auto button. (below the word auto there are 3 buttons. Press the one on the far left that has no other markings on it. This will only take 2 or 3 times back and forth.

When the display is blank enter the number 14 (like you were making 14 copies of something) then press the Green (start?) button. Let the copier warm up about 30 seconds and try making a copy.

It worked for me. Still having trouble call Sharp USA 630-378-3590 or Canada 905-568-7140. They were quick and helpful
