Epson Aculaser compatible toner refill kits are

The refill process is really that simple since the Epson CX11NF cartridge come designed with an easy to open toner fill hole. In the process of refill, the user will simply have to twist the upper part of the cartridge and release the lock. This will open the toner waste chamber that precedes the toner supply chamber. After emptying the waste chamber, the toner supply chamber fill hole will appear. A cap seals the supply chamber which needs to be plucked out before chamber maintenance and compatible toner powder transfer can commence.

CX11NF print cartridges also come with a lockout chip (not a killer chip) that the user can actually ignore and proceed with print jobs. But then again, toner level indicators will cease to function without the replacement of the lockout chip. So to restore the toner indicator function, the user will simply have to install a new reset chip that comes packaged with toner refill kits.

Don't just dispose the empty toner cartridges of the Epson Aculaser CX11NF laser printer after it has run out of toner supply. The toner cartridge is still good for up to 3 refills and all it needs is new shot of toner from a compatible Epson toner refill kit.
