    I used the control buttons , I did it manually and I also went into the stup and changed them there. The changes made no difference (did not darken at all). Every copy is a light gray rather than black

    My copies and print jobs were coming out really faded, even though the replace toner light had not come on. I replaced the toner anyway and the copies are still light and blotchy. any suggestions?

It will copy but the it will light and faded. Hard to read.

Too much moisture in the paper will cause blotchy, light and faded print. Run the copy through a second time on the reverse side. If the second side is good you have a paper moisture problem. (Usually happens in non-airconditioned spaces during humid periods if the paper has been stored in the open.) Hope this helps.

Do you know how to reset the drum counter for Sharp Al-1641

Reset the drum count by pressing "Clear" then "Exposure Mode" then "Clear" then "Exposure Mode"
Exposure mode is far left key on panel. You need to do this fairly quickly so that the display goes blank.
Once display goes blank then key in 24 then press print, then key in 7 then press print. You should now be getting flashing 000
Turn machine off then on and light should be gone.
Short version: C,far left,C,far left,24,print,7,print

The AL1000 drum unit is the same as the AL1641 drum.
I do not recognize the MS1DR as a sharp part number.
You can reset the drum indicator by pressing these keys in sequence:
Press "C" then press "Exposure Mode" then "C" again then "Exposure Mode" again.
Note that the Exposure Mode key is the far left key on the panel.
One you press these 4 keys in sequence the display should go blank. Then key in 24 as if to make 24 copies. Then press Print (Green Button)
Then key in 7 as if to make 7 copies.
Press print again. You should now get flashing 000.
Turn machine off then back on and the light should be gone.
Here it is in a short version:
C, far left, C, far left, 24, print, 7, print,
then power off and back on.
This should make the copier operational again if all you have is the drum light.

2 lines down the right side of paper - sharp 1641 CS copier

Your problem is most likely not the drum.
Can you make a copy on the glass itself and the lines DO not appear?
if yes this confirms it is not from the drum. Open the top and look at the Small strip of glass : is it dirty or have two dots, white out or Anything on there???? clean w/ alcohol. Any dots will look like lines when making a copy because the paper is moving on the glass.
If the lines are still coming out even on the glass then take a look at the Fuser (exit where it gets hot) are the rollers smooth and uniform or are they scratched???

AL1641 CS won't make two sided copies anymore

Sounds like a driver or configuration problem, 1st) Make sure when you are printing, to go to Properties, you must choose 2-sided printing each time on that model, some programs won't allow you to change your printers settings.
2nd) go to control panel/ printers/ Al-1641, right click, properties, In the first tab General it should say at the bottom (Double sided - Yes) If not you need to delete the driver, a fairly common problem, and reload the driver, get the driver from Sharps website to be sure you have the most current driver, if a driver is corrupt it won't tell you there is a problem, make sure it allows you to print two sided.
