With respect to your HP OJ J4680 printer, which uses HP 901/901XL ink cartridges, it sounds like this is either a compatible/clone cartridge from overseas in which case you should not remove the orange top as it is molded into the cartridge, or you recently purchased or had the ink cartridge refilled (at Costco, etc.) and the storage clip (which seals the base of the cartridges to prevent the nozzles from drying out) is attached to the ink cartridge. If this is a storage clip, just press hard on the clips top lever at an angle to remove. See our videos on cartridge care tips and how to troubleshoot an ink cartridge error/problem on the HP OJ J4500, J4600 and OJ 4500 series printer models:
If you need to purchase new HP 901 ink cartridge(s) and are trying to cut costs, we suggest you try a remanufactured ink cartridge from http://www.inkplicity.com/ as their ink cartridges typically have the lowest cost in the USA, have a high reliability rating, come with a 1-year warranty and provide free shipping for all orders above $20.
NOTE: If you are interested in the top \'refill friendly inkjet printer models\', our suggested list is posted on-line and our internal labs have verified there are no issues (in ink compatibility or color output) with all of these models: http://inkjet411.com/?page_id=3585
Regarding your HP Officjet Pro 8600 printer and refilled HP 950/951 ink cartridges and the "low ink" messages. Depending on your ink refiller (or if you did it yourself?), a replacement chip may or may not have been installed with the recently refilled cartridge(s). Refer to picture on our support site to first determine which type of cartridge configuration you have, then refer to the applicable section to address the current cartridge error(s) or printer issues. http://inkjet411.com/?page_id=1999
NOTE: Costco USA's Ink Refill service now 'chips' all refilled ink cartridges which fully restores all functions to that of a regular HP (OEM) ink cartridge and customer experience. For USA ink refill store locations and details on ink refill pricing:
Refer to Section A if your refiller attached a new replacement chip (green in color) onto the cartridge. Refer to Section B if only the original HP chip is attached.
CAUTION: Be advised, the use of compatible/clone cartridges (i.e. sold thru the internet from China) are known to be problematic and may cause printer errors and/or permanent PRINTHEAD failures (due to incompatible ink formulations). We do NOT suggest refilling these types of ink cartridges.....refilling of original/genuine ink cartridges is only suggested! HP original/genuine ink cartridges can be identified by the visible HP logo on the front label of the cartridge.
the most important is to remove all the air from the cartridge that has left inside durring refilling that is why professionals are using special machines that refill in 0 air πρεσυρε using vaccum pump
you can check here a video on how to refill with out any special equipment
It is always recommended to use genuine HP cartridges.
As if we will use the non HP or refilled cartridges, it will reduce the life of the printer.
And we will get an error "cartridge problem".
Plaese use the below cartridges, which are compatible with this printer.

USING THIS TYPE OF REFILLS JUST ISN'T A GOOD IDEA. THE INK IS NOT THE SAME AS HP CARTRIDGE INK AND YOUR PRINTER WAS MADE FOR HP INK, NOT SOME GENERIC BRAND. THE FACT THAT IT DOESN'T WORK UNLESS YOU STICK IT IN WATER, ETC. SHOULD TELL YOU SOMETHING IS WRONG HERE. REFILLING IS MESSY, AND CAN CAUSE LEAKS IN YOUR PRINTER AND REALLY MESS THINGS UP. THE BEST BET IS TO USE THE PROPER INK CARTRIDGE WITH YOUR PRINTER. THATS THE TYPE OF INK IT WAS DESIGNED FOR.
HP #74 Cartridge Refill Instructions Black cartridge
1. Put the cartridge on some paper towels in an area where you can tolerate a spill.
2. Peal off the top label.
3. Fill the syringe with 20ml. of black ink.
4. Very S-L-O-W-L-Y inject ink into any hole (they all go to the same sponge, HP just used the same color mold for the black ink cartridges).
5. When finished, replace the top label or leave it off (it will make no difference in the printing).
6. Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions. Or print the following pages: http://www.refillinstructions.com/black.htm for Black
For best results, leave cartridge in printer for 8 hours after refilling so the ink can saturate the entire sponge. A Refill Kit should include Ink plus the following: One 30cc Syringe
