The cartridge fits in the printer and the toner gives a similar darkness to OEM toner. However, the cartridge is not fully compatible with the Dell 1125 MFP; while the chip is valid and the toner works, the physical design of the cartridge is incompatible. Due to the position of the chip underneath the cartridge, it does not make proper contact with the printer and will be rejected. I had to unscrew the chip from the cartridge and tape it directly to the correct spot inside the printer in order to use this cartridge. Furthermore, the top of the cartridge is not shaped correctly to allow the arm of the printer drum to latch into it, preventing proper seating. I had to permanently alter the shape of the drum arm to allow the cartridge to sit properly. This was not a problem when I purchased this item years ago, but I imagine the supplier has since changed. Unfortunately this may be your only option for a decent cartridge since the Dell 1125 is so old, but be warned that you will need to make physical changes to get it working properly.
