Cutting off top of line of print but only an occasional line.

Per HP: After installing a new print cartridge, a message appears on the front panel that the print cartridge is low on ink. This may be caused by installing the cartridges with the power turned off. Cartridges should always be installed with the power turned on.

Found the following directions online:
How to Replace an Empty Ink Cartridge in the HP Deskjet 2540 All in One...

Replace the ink-cartridges, because they are just about empty.
When ink is pulled from the cartridge, there is just enough ink to print a "low-density" page,
or a few lines of text, but there's not enough ink to "freely" flow, on demand, to ink a full page.

Sorry to hear that.. here are some instructions that should help you out:

Instructions

things you'll need: Microfiber cloth

1. Ink Cartridge Errors
2. Turn the printer on and open the ink cartridge cover. Wait for the cartridge carriage to stop completely before reaching into the printer.
3. Press on the top of each print cartridge, then pull the cartridges free from the carriage. Make sure you are only using HP cartridges labeled as "HP 60" or "HP 60XL."
4. Reinstall the ink cartridges and close the cover. If the ink cartridge error message displays again, remove the ink cartridges as before.
5. Clean the copper metal contacts on the cartridges using a dry microfiber cloth. If you still see the error message after you reinstall the ink cartridges, replace hem with new cartridges.

Print using the device's ink backup mode if you do not have a replacement for one of the cartridges. Remove the cartridge you cannot replace and close the cover and continue printing. The printer will automatically use the backup mode until you install a new cartridge.
