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.

Either the toner cartridge is very close to empty or the drum unit needs to be replaced. Check your warning lights. Yellow = toner, red = drum. If no warning lights, pull out the toner/drum unit and remove the toner cartridge. Have a look at the cylinder in the drum (DR2125) - if it is very black and matt looking you will need to have it cleaned or just replace it.
The triangle or stack of 6 dots is the toner cartridge light. The drum light looks like a cylinder or aa battery.
If you open the right side door, then the front door you will see the 2 cartridges. The toner cartridge is on the left and should have a large green button you push down on to release and slide out. Later or when needed you can slide out the drum cartridge AFTER you remove the toner.
You might have a local source to get your toner cartridge refilled. Or just order a new one and unpack it, then slide it in and your all set.
About $50 for refill or about $100 for new.
A solid red STATUS light with a solid yellow TONER light indicates toner out...replace according to pg. 63 in the manual.
It can also indicate a cartridge position error. Take the DRUM UNIT out of the machine and re-install.
A solid red STATUS light only means:
Front cover open
Fuser cover open
Dust on drum
Too many trays
you have indeed changed almost everything. and sadly many parts that you didn't need changing. Could you have a bad hose at the wheels or a leaking caliper? if all else fails I would start by blocking off one circuit of the braking system...with a plug, and checking for leaks in the active system and then switching sides. Is the system being totally bled? that means first at the master cylinder, then at the abs cluster and then each wheel...twice.
