These cartridges are very easy to refill. It takes less then 3 minutes to complete the job, even if it's your first time. NO special tools needed. Only one screw needs to be removed and than open the refill cap to fill it up. These toners are Brand New in a factory sealed bottle and warranted to be free from defect.

I ship the toner with detailed instructions and a screw-on funnel with each shipment. Each bottle is filled with 190gms/color & 200 gms/black of toner. This should fulfill about 5000 page yield @ 5% coverage.

The Starter Toner Cartridges shipped with these models do not have a built in toner detection mechanism inside as do standard replacement consumable toners. This will cause the "Order Toner" message to remain, even after refilling of the starter cartridges.
