Refill Instructions for HP LaserJetPro P 1100, 1101, 1102, M1210, 1212, CE285A

Remove the toner cartridge HP LaserJetPro P 1100, 1101, 1102, M1210, 1212, CE285A from your printer and place it on the table in front of you. As this cartridge is not equipped with a filler opening you need to prepare one. We recommend using a soldering iron for that. Burn a hole into the cartridge at the point shown in picture 1.

Deburr the hole thoroughly and make sure that no plastic splinters get into the cartridge, because they could damage the mechanics. Before refilling the toner cartridge, you should pour out the rest of the toner powder. Otherwise, the physical and chemical characteristics of the old and the new toner powders could lead to clotting.

Screw the funnel onto the toner bottle to facilitate refilling Carefully shake the bottle and fill the powder into the cartridge (picture 3). After refilling the cartridge you need to reseal it. For this purpose, cut a piece of fabric adhesive tape to size and glue it onto the filler opening.

As the HP LaserJet Pro P1100, 1101, 1102, M1210, 1212 cartridge is equipped with a toner chip that monitors the filling level of the cartridge, you have to exchange it after each refill. Put the replacement chip in the same place as the old one (picture 4). Fix it with a drop of hot glue if necessary.

Once the chip is exchanged, your printer recognises the cartridge as full. We recommend refilling the cartridge when exchanging the chip in order to achieve the full printing capacity. Otherwise, the cartridge may not be reset due to the lack of toner powder. In this case, the replacement chip does not work. The replacement chip is useable once.
