Verify that the unit is on. Open the print cartridge door allowing the print carriage to move to the far right side of the unit. Once the print carriage has stopped, lightly press down on a print cartridge to release it. Pull the print cartridge toward you out of its slot. To replace the tri-color print cartridge, remove the print cartridge from the slot on the left. To replace the black or photo print cartridge, remove the print cartridge from the slot on the right. Place the cartridge in a plastic bag as it may still contain some residual ink and may leak.

Tips & Warnings
If you use a refilled or re-manufactured print cartridge, the ink level indicator will be inaccurate or unavailable.
An ink cartridge might be running low even if the graphic shows that there is ink remaining. When the cartridges begin to run out of ink lines or streaks will always appear in printouts.
If you are removing the black print cartridge in order to install the photo print cartridge, store the black print cartridge in the print cartridge protector or an airtight plastic container.
The HP Inkjet Supplies Recycling Program is available in many countries/regions, and lets you recycle used print cartridges free of charge.
If the unit is off when you open the print cartridge door, the unit will not release the cartridges for changing. You could damage the unit if the print cartridges are not docked safely on the right side when you try to remove them.
Do not touch the copper-colored contacts or ink nozzles. Touching these parts may result in clogs, ink failure and bad electrical connections.
