You could try this way first as its a lot quicker and easier than the official steps from HP:
Just hold down the ENTER button and then press the MENU button. There will be a series of 3 fast, high beeps. Then everything resists and is a-okay. Both problems go away.

The ink cartridge-related error messages may occur due to one
of the following reasons:
* The ink cartridge does not make a proper electrical contact
* The cartridge is bad or wrong
* The cartridge is remanufactured or refilled
To resolve the error, follow these steps:
Step one: Check the print cartridges and clean the cartridge contacts
Even if the cartridge is new, follow these steps to clean the print
cartridge contacts. Print cartridges have a substance on the contacts
to keep them from corroding during storage that may cause poor
electrical contact between the print carriage and the print cartridge.
1. Verify that the product is turned on.
NOTE: If the HP product is not turned on, you will not be able to
remove the print cartridges.
2. Open the top cover or the cartridge access door in one of the
* Pull the control panel forward and then lift the top section
toward the back.
* Open the access door on the left or right of the unit. This door
may be located under the scanner glass lid on some flatbed
* On many flatbed products, you raise the front center section of
the unit to access the print cartridges.
* Raise the cartridge access door on the front of the product.
3. After the print carriage stops moving, unplug the power cord. You
must unplug the power cord to prevent the print carriage from
4. Remove both print cartridges.
5. Verify that the part number on the cartridge is the correct part
number for the all-in-one and that the carriage is not blocked
preventing the cartridges from moving. Visit the following HP Web
site for a cartridge compatibility chart.http://h10025.www1.hp.com/ewfrf/wc/genericDocument?lc=en&cc=us&docname=bpa00586
6. The electrical contacts of the print cartridge are coated with a
thin layer of grease to protect them from oxidation. This grease
may inhibit the electrical connection and should be removed. Using
a cotton swab or cloth lightly moistened with distilled, filtered,
or bottled water, clean the electrical contacts of the cartridge.
This usually occurs with a new ink cartridge, but may also occur
with an older cartridge.
NOTE: When an all-in-one is used frequently for black and white
printing but infrequently for color printing (for example,
an all-in-one that is used primarily as a fax machine), the
color cartridge will still eventually fail and need to be
replaced. The pins in the print carriage can cause dents
on the contact points of the color cartridge over time
(usually between six and twelve months).
7. Wipe the contacts with a dry, cotton cloth.
8. Reinsert the cartridges and lock them in place.
9. Close the top cover or access door and plug in the power cord.
10. If the error persists, repeat these steps. If further cleaning
fails to resolve the error, proceed to "Step two: Clean the
print carriage contacts" section.
Step two: Clean the print carriage contacts
Have the following materials available to clean the print carriage
* Cotton swabs or any soft material that will not come apart or leave
fibers (for example, a scrap piece of clean cotton cloth).
* Distilled, filtered, or bottled water (tap water may contain
contaminants that can damage the print cartridges).
CAUTION: Be careful not to get ink on hands or clothing.
To clean the cartridge contacts inside the product, follow these steps:
1. Turn on the unit.
2. Open the top cover or cartridge access door.
3. After the print carriage stops moving, unplug the power cord.
4. Remove both print cartridges.
5. Using a cotton swab or cloth lightly moistened with distilled,
filtered, or bottled water, clean the electrical contacts of the
6. On models equipped with locking latches, lower the latches.
7. Wait five to ten minutes for the contacts to dry and then plug in
the power cord. The unit will begin to reinitialize. Wait until
the process is complete before proceeding.
8. Reinsert the print cartridges when prompted and then close the top
cover or access door.
9. If the message recurs, replace the print cartridge indicated by the
* If you are using refilled or remanufactured cartridges or non-HP
cartridges, replace them with new HP cartridges. HP cannot
guarantee that refilled or non-HP cartridges will function
correctly in HP products.
10. If the problem still exists, replace both print cartridges. Since
the cartridges are electronically connected through the printed
circuit board, the cartridge not indicated in the message might be
the causing the failure.
