I just repalce the drum unit for the first time & did it by the instructions in the manual, but the "drum replacement indicator light" is still lit. I have tried reseating both the drum & toner as well powering unit off & on. The light remains lit. Any ideas or suggestions?

These are very good machines so I would see no reason to replace it. Do you have the operators manual? If so look up the setting for "toner save mode" and make sure it is NOT turned on.
The drum unit is good for at least 18,000 pages so I would not suspect the drum. I even reset the counters on the drum units and can get up to 36,000 pages on them. Do you have the machine hooked to a PC for printing? If so is there any difference between printer density and copy density? If so then the issue is with the scanner density setting. If the copy and prints are both light then it is a print engine problem. If several toner cartridges are doing the same light print then I would suspect that your laser scanner optics are dirty. There is a narrow strip or slot just above the drum unit that the laser beam goes thru to write the image onto the drum. This should be cleaned and then the machine re-tested. If no improvement is see then the machine will have to be dis-assembled and cleaned which would require a compentant service technician.
Good Luck and Thank You for using Fixya.
Was the copier working fine before you changed the cartridge? If so I think your cartridge is the problem. If it started making blank copies right after you changed it. If this is not the case the first thing I would say is it is not the drum. Try opening and closing the right side door. There are contacts in the door that will cause blank copies. I have had several customers do this and it fixed the problem. You can also try pulling out the toner and then pull the drum unit partially out and re-seat it. Then re-install the toner.
The red light that looks like an empty cylinder on the Sharp AL 1631 Grayscale Copier panel is the "drum replacement required" indicator. The "cartridge replacement" indicator is represented by 6 dots forming a triangular shape.
The drum replacement indicator lights up when there are about 1000 copies left until its end of life. It is only when the indicator starts blinking that the drum really needs replacement.
The part number for the drum is AL-100DR.
I hope this helps.
the problem in your machine is on the drum unit there is a arching on the mc unit.located in the upper portion of the drum unit.if you have an old drum unit try to install it again just for testing.and check if ther is a dumping toner again.
Your unit definetly needs a new drum. The usual yield for this consumable is upt ot 15,000 pages, so at the stated rate, the unit yielded more than average. AL-1000 series share the same toner and drum, so finding remanufactured (or recycled) drum units should be no problem. In Puerto Rico, they are sold for about $79.00.
