My printer won't print

[JHeart1]

I have a HP Photosnart 7520 that has worked well for several years. About a week ago it started printing blanks ( both ways just duplicating a copy or printing from the computer).. 

I changed the ink jet and it still comes out blank. Any ideas?

Welcome to HP support community.

Make sure the ink cartridges are properly vented and seated correctly

1. Turn on the printer, if it is not already on.

2. Open the ink cartridge access door.

   The carriage moves to the access area.

   

3. Wait until the carriage stops moving before you continue.

4. Press the tab on the front of the ink cartridge inward to release it, and then pull up on the ink cartridge to remove it from the slot.

   

5. Examine the vent area on each ink cartridge, above the HP logo on the top of the ink cartridge.

   

6. If the ink cartridge still has the pull tab attached, pull to remove it.

   

7. If the vent is clogged, use a straight pin to gently remove excess adhesive from the vent.

8. 1. 

      Clogged vent

   2. With a straight pin, gently remove excess adhesive from the vent

   3. Unclogged vent

9. With the nozzle and the contacts facing down, slide the ink cartridge into its slot. Press down on the ink cartridge until it snaps into place. Make sure the color icon on the ink cartridge label matches the color icon on the slot.

   

10. Repeat these steps to inspect the vents on each ink cartridge.

11. Make sure each ink cartridge is firmly in place in its slot. Run your finger along the top of the cartridges to feel for any that are protruding, and if any are, press down firmly until each ink cartridge snaps into place.

12. Close the ink cartridge access door.
