Cartridge Problem - HP Officejet Pro 8600

[Zoc21]

Got message to replace black ink. Did so with brand new HP black Ink. Got messages one or more cartridge appears to be damaged K. 

Took brand new ink back to Officeworks and replaced it.

Still getting messages.
have reset numerous times as per instructions

have taken ink cartridges in and out

have take whole cartridge holder out and in.

Then it started saying black was fine and yellow needed ink - so replaced it. 

Now it just swaps between saying yellow cartridge damaged or black cartridge damaged. 

keep going round in circles. Black will be fine then yellow wont be and vice versa.

Hi @Zoc21,

Welcome to the HP Support Community

I understand you are facing an issue with your HP Officejet Pro 8600 Printer -cartridges issue. Not to worry I will help you to get a resolution to resolve the issue.

Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove the USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till the warm-up period finishes and the printer is idle

Update the printer firmware

1.   Open the cartridge drawer when the print head is all the way to the right.   This will cause the print head to transit slowly to the left.

2.  When the print head is in the approximate center of the printer, power down the whole printer, by shutting down power to the unit, at the level of the 'mains' or wall, by pulling the plug.  The print head is now accessible from both sides and the front.

3.  Locate a white lever on the right side of the print head, as you face the front of the printer.  This lever is about 5cm long. Carefully move this level towards you. This will release the whole print head including the cartridges, from any mechanical or electrical attachment to the printer.

4.  Carefully lift the print head, which is now free of any restraint, towards you and out of the unit.

5.  Prepare a kit of cleaning agents, including an isopropyl alcohol wash-down bottle, wipes, swabs, and a flat basin about 25cm x 25cm x 4cm.

6.  Remove all the cartridges.  And set aside.

7.  Look to see which transparent reservoirs in the print head do not have ink in them.  If you see one without ink, and the cartridge is good, clean the receptacle for that ink on the print head with a flow of alcohol, and the corresponding spout of that cartridge with a clear stream of alcohol. 

8.  Carefully rinse away the surplus ink built up on the print head with alcohol.

9.   Lightly wipe the print head nozzles with alcohol using a wipe approved for use on optics, e.g. very low lint.

10. Wipe all electrical contact.

11. Reassemble.

12. Power up.

13. Do a clean bootup of the system software, from internal memory.  This will cause the machine to forget the error code

14. Re-initialize the machine, and re-establish blue tooth links.

15. Print a test sheet, which will cause the print heads to re-align.

16. Go back to work.
