HP Easy Refill Kit for (HP) Color Inkjet Cartridges Printer

I had that happen before. It turns out the refilled toner cartridge I was using was the problem. When I bought the cartridge I thought I was getting a new one. They were refills. You may want to try another cartridge if you have one.
Good Luck

Hi follow these steps..

1.Purchase a refill kit for your model of printer. It is important to purchase a refill kit designed for your specific model, since generic refill kits do not work well with HP printers. There are a number of places to buy these kits, but you must make sure you get the right kit for your printer model

2.Take the toner out of the printer and clean it carefully. Over time toner cartridges will accumulate paper dust, dried toner and other debris, and all of this must be cleaned away before the cartridge is refilled.

3.Flip the cover out of the way to expose the developer roller, then use a soft clean cloth to clean the roller. It is important to clean this roller before refilling the cartridge.

4.Make a small hole in the toner cartridge, using the instructions provided in the refill kit. It is important to follow the refill kit instructions carefully, since the toner refill process will vary from model to model.

5.Place the replacement toner in the hopper, then carefully pour it into the HP cartridge. Be careful not to spill any of the toner, and if you do spill the toner be sure to clean it up promptly. Reseal the hole you made after the cartridge has been refilled.

6.Sit the refilled HP cartridge on a clean flat surface and let it remain there for 20-30 minutes. Pick up the cartridge and make sure no toner has leaked out. If you do see any leaks you will need to reseal the hole you made again.

7.Pick up the cartridge and make sure no toner has leaked out. If you do see any leaks you will need to reseal the hole you made again.

Good Luck & cheers:-)

How To Refill Ink In Printer Cartridges – Video Instructions

Inkjet toner refill - Beware: Non-original Toners Can Cost 31% More Than Original HP! www.HP.com/IN/Toner Stop Check Fraud Now - Prevent Check Fraud with Source Technologies MICR Printers! www.SourceTech.com This video illustrates the various steps required to refill printer cartridges at home using disposable syringe and a bottle of printer ink.

You should not refill the cartridge...they are a one time use only in any HP laser printer. To use a refilled or refurbished cartridge either voids your warranty, and if you have a printing defect as the result of not using HP-branded toner or an refurbished cartridge HP will not be able to do anything for you...I used to work for one of their call centers doing printer support, and this was a common theme.

There are many places that may advertise that they refill the cartridges with HP-approved toner, but that is far from true. In order to keep your printer functioning properly, even though it may cost more, it is in your best interest to only use new HP cartridges in your unit.
