Question edited for clarity, 'sharp at 5516' to 'Sharp AR-5516'.

Remove the toner cartridge and clean the contacts on both the cartridge and the copier with alcohol. Tap the cartridge on both ends to settle the toner. Make sure you are using genuine Sharp replacements.

Make sure genuine toner is inserted...If problem still persist, check or replace CTIF sensor located inside the machine where the springs touching the toner cartridge chip.

1. Make sure genuine toner is use
2. Toner chip not dirty
3. Toner detection inside the machine not dirty

When replacing the toner cartridge, you MUST install a brand new, unused genuine Brother toner cartridge in order to reset the toner status. Swapping toner cartridges from one machine to another or installing a partially used toner cartridge may cause this problem. Brother machines control their image quality for the most suitable print quality by monitoring toner consumption. If you install a partially used toner cartridge, your Brother machine is unable to recognize toner consumption correctly which will cause this problem. Therefore, when you replace the toner cartridge, please use a brand new toner cartridge, not a partially used toner cartridge from another machine.

Treat the same as "Non-Genuine Toner". Caused by installing a refilled toner cartridge or taking out cartridge out, putting a new toner, and then putting the old one back in. Place a new toner in the machine, change SP5-051-001 to 1, and cycle power.

may be you refilled the toner more than 2 -3 times or may be the toner is not propery refilled i advise you to install new genuine toner it will resove problem.

The copier has an "eye" that detects when the waste toner bottle is full. If you dump it and reuse it, the residue can build up and cause the machine to "think" the bottle is still full. I experienced the same problem. If you re-use an old bottle, after emptying, rinse our any remaining residue and dry the bottle out. Your copier should then notice the bottle being empty.
