The latch holding the [black] ink cartridge has broken on my hp psc photosmart all-in-one printer.

Wipe Down the Cartridge Contacts

Turn on the printer and open the cover where the ink cartridge is located. Remove the cartridge.

Remove the cartridge and use a clean, lint-free, dry cloth to gently wipe the contacts.

Wipe from the top of the contact to the bottom. Do this for each contact.

Place the HP ink cartridge back in the carriage. Turn the printer off for a minute.

Turn the HP printer on. Use the printer to print a test page. If this does not correct the problem, move onto Section 3.
Reset the HP Deskjet and Photosmart Printers

Turn on the HP Deskjet or Photosmart printer, open the cover and remove both the black and color cartridge. Close the cover.

Remove the power cord from the outlet and disconnect the cables running to the computer and/or router. Wait one minute, and then plug in the power cord and then the cables.

Open the cover and install the black and color ink cartridges. Turn the printer on.

Turn the HP printer on. Use the printer to print a test page. If this does not correct the problem, you will need to buy new ink cartridges. Office Max or Wal-Mart have ink cartridges for almost every model of HP Deskjet, Photosmart and Officejet printers.
Reset the HP Officejet and HP PSC All-in-one Printers

Turn on the Officejet or PSC all-in-one printers.

Unplug the power cord from the back of the printer and wait one minute.

Plug the power cord back into the printer. Press the On button and hold until printer turns on.

Print a test page to see if this has fixed the problem. If not, you will need to buy a new color ink unit at any office supply store such as Office Max.

1. Prepare the replacement cartridge by pressing down and back on the top of the protective plastic, then sliding the cartridge out.
2. Set both the cartridge and empty cartridge protector aside.
3. Turn on your printer and lift the access door until it locks into place. The print carriage will move to the center.
4. Once the print carriage has stopped moving, raise the latch to release the empty cartridge. 5. Remove the empty cartridge by pulling towards you. If you are replacing the tri-color cartridge and need to remove the black ink cartridge temporarily, use the empty cartridge protector to hold it. 6. Hold the replacement cartridge by the sides and remove the black plastic tape. 7. Insert the replacement cartridge into the appropriate slot (left for tri-color, right for black) until it snaps into place. 8. Pull the cartridge latch towards you and press down until it snaps into place. 9. Close the access door. -------
