Replacing the print cartridges

1. Turn on the HP Officejet, and lift open the print-carriage access door. The print carriage will move into the access area. Figure 1: Opening the print-carriage access door
2. After the carriage stops moving, push down on the top of the print cartridge to release it, and then pull it toward you out of the slot. Figure 2: Removing the print cartridge NOTE: It is normal to see ink buildup in the print cartridge slots.
3. Remove the new print cartridge from the packaging and gently remove the plastic tape by using the pink pull tab. CAUTION: Do not touch the copper contacts or ink nozzles. Install the cartridge immediately upon removing the tape to prevent ink from drying in the nozzles. Figure 3: Removing the plastic tape
4. Push the new print cartridge into the appropriate slot at a slight angle, until it clicks into place. CAUTION: Do not attempt to push the cartridge straight into the slot. It must slide in at a slight angle. Figure 4: Inserting the print cartridge
5. Close the print-carriage access door.

Back to top Aligning the print cartridges The HP Officejet will prompt you to align the print cartridges every time you install a new print cartridge to assure high-quality output.

1. When the message displays, press OK . The HP Officejet will print an alignment page.
2. Place the alignment page face down on the left front corner of the glass with the top of the page facing the left side.
3. Press OK . The HP Officejet will align the print cartridges and display Alignment Complete .

First, turn off the printer. Then open the print-carriage access door.

After the print carriage moves, push down on the top of the print cartridge to release it and pull it toward you. Once removed from the slot, you may now insert the new print cartridge.

You have to push the new print cartridge into the slot at a slight angle until it clicks into place.

Then close the print-carriage access door.

I hope this helps.
