I replaced the color ink cartridge. Now there is an "E" flashing alternately with a "5". The alarm light is on steadily, and the black ink and color ink lights are flashing. How do I...


E5 is a Cartridge cannot be recognized error.
Reinstalling the cartridge could clear the alarm.
If this does not work,
Removed both ink cartridges.
Turn off printer and unplug fron electrical outlet.
Wait at least 5 minutes.
This will let the printer reset itself.
Plug printer back in and turn on.
Printer will cycle and an E5 will appear.
Installed back ink cartridges.

Error: Right cartridge incorrect


Try Remove and reseat the cartridge
Remove the cartridges and Clean the contacts
Use Clean cotton swabs or any soft, lint-free material that will not stick to the cartridges
Remove the problem cartridge
Place the cartridge on a piece of paper with the nozzle plate facing up
Unplug the unit power cord
Lightly moisten the lint-free cleaning material with clean water. Clean the cartridge contacts. Avoid touching the nozzles. Replace the cleaning material if it gets dirty. If that doesnt resolve the issue than you have to download the firmware update. Link for the firmware update is http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=oj-14039-3&lc=en&dlc=en&cc=us&lang=en&os=228&product=79499

Flashing red light


On the alarm and data light blinking, it is saying the toner cartridge is empty. You will need to replace it. Once in a while you can remove the toner cartridge and shake it and have it work for a little while longer. This does not work all the time however.
If you can't get it to work by shaking it, you will need to purchase a new toner cartridge.

When you have the new cartridge, you will need to slide the blue corona wire cleaner back and forth. This is just in front of the toner cartridge in the drum unit on the top of the drum unit. There is a small light blue colored piece of plastic with an arrow in it that you will just push back and forth. This will help the drum unit do its job better.
