Re: drum cartridge - generic

Sharpe are correct there is no known button sequence I know about as the drum normally has a resistor that blows when installed resetting the drum count.

Thanks J

I replaced a new drum cartridge for Sharp AL-1631 Copier, but the warning indicator light is still on and the copier is not working.

To reset the drum light on just about any Sharp AL series copier press the following key's in sequence and as quickly as possible (with 4 seconds for the first 4 keys)
Press "C" then the far left key (exposure mode) then the "C" key then the far left again.
So in other words C, far left, C, far left
If done correctly the display should go blank.
Then key in 24 as if you were going to make 24 copies.
Now press the "print" button
Now key in 7 as if you were making 7 copies
Now press the print button again.
You should now be getting flashing zero's on the display.
Turn the machine off then on again and your drum light should be gone!
Good Luck and Thank You for using Fixya.

I have a SHARP al-1661cs copier/printer. i keep getting a "replace TD cartridge" message. I have replaced the cartridge and it still come on every couple of days. i take the cartridge out, shake it and the...

Are you having your cartridges refilled?
By "replace TD cartridge" message do you mean the little stack of 6 red dots on the control panel?
The sensor for this condition is contained within the toner cartridge. The sensor reads the mixture of developer to toner ratio and tells the machine to add toner when needed. If you are having this problem with 3 different toner cartridges then I would suspect the toner add drive system. If you are having just the 1 cartridge refilled and have had the problem with the last 3 refills then the cartridge itself may be the problem.
I'll let you repond then we will see if further info is required.
Thank You for using Fixya.

You can reset this 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.

Bad copy from Sharp AL-1661CS

Try print from a pc, if those lines still appear then you should replace the drum unit. If not then clean the copy glass and the scanning mirrors.

Average useful life of Sharp AL-1661CS

With that machine the toner cartridge also contains developer. Without getting too in depth, it sounds like maybe your toner cartridge is leaking a bit of developer which takes with it a bit of toner. Developer is made up of tiny metal particles which are supposed to stay inside the developer unit. As the seals wear in the developer unit (which is part of the cartridge) it allows a little to leak out causing the problems you are seeing.
When you take the toner cart. out, at the rear side (part that goes the furthest into the machine) you'll see a white foam seal. If you notice some excess toner (and probably developer) sticking straight out from that, it could be that the seal has a jagged edge which is dragging developer off of the magnetic roller and depositing it on the drum making the line you speak of on the left hand side.
Also check to make sure the copier is sitting level, if it's not then the concentration of toner at one end of the developer unit is too great and some can be allowed to spill out.

So in short, it's probably not the drum that's at fault, it's more likely the toner cartridge.

Is it worth replacing? There's no easy way to answer that. If the machine is used in a fairly high volume workplace, it's probably worth replacing. If you could get by with a smaller cheaper machine (brother, HP, lexmark etc.) that does printing, scanning, faxing and copying you may be better off.

Please Help -- Erroneous Lines from Auto-Paper-Feeder

Not familiar with this particular machine, but it sounds like one which uses a seperate scanner when drawing originals from the sheet feeder. Have a look to see if there's a glass strip to the side of the main copier face. If so, give that a careful clean. A.
