Need instructions to put in refilll cartridge

Sounds like you may have a buildup of calcium in the water line. Try putting in some LimeAway and letting it sit overnight to clear it out. The drain the LimeAway out refilll and steam a few times on scrap cloth to get all of the cleaner out, see id that solves the problem.

both actually. Use a rinse agent (jetdry) in the dispenser and refilll and needed it dispenses about 2 tear drop sized drops on the rinse cycle, Vinegar will clean any nasty things left behind once cycle is done it can be used about every 2-3 months

Have you tried brand new HP cartridges? If so have you taken the paper off of them? I wouldn't reuse a cartridge that has dried up.

TAKE A CAN OF AIR AND SPRAY INTO THE INK HOSE THIS WILL WORK

make sure that use only the HP genuine cartridges. If u uses the refillled cartridges it will damage your printer.

Hp printers cartridges have a circuit, which could be damaged in your case. That is the reason you are getting the error message. However, The use of refilled print cartridges alone does not affect either the warranty or any maintenance contract purchased from HP for its Inkjet printers. Repair will not be covered under the warranty or by the maintenance contract if an HP Inkjet printer failure or damage is found to be directly attributed to the use of a modified or refilled HP Inkjet print cartridge.
I strongly sugget you to use HP genuine ink cartrdiges. I understand that wont work out economically.

The instructions always come with the new cartridges and also are printed on the new cartridges. You move the right hand (colored) side up to unlock. Carefully pull the cartridge up and out (you can screw up the gears if you don't put the cartridges in and out straight. Make sure you've followed the instructions that come with the new toner cartridge (removing tape, shaking), put it in the same way and move the right hand side down to lock.

if you have replaced the toner unit the main cpu is bad not realLY worth fixing but this is a very good copier you can get them on ebay , this the only copier you can refilll the toner unit for $6 & DRUM FOR $15 get a AL1655 best deal

You can refill them but you have to do it striaght away otherwise it dries up and is knackered. Do it yourself remove the label on top and drill 3 holes for the colour (you can get a guide for it with refill kits) sending them somewhere will cause them to dry up, as they need doing as soon as you loose a colour.
For now get a new cart and fill that when it runs out.

it's # and 6.

1. without turning the unit off, unplug the power cord from the back of the product.
2. press and hold # and 6 keys.
3. while holding those keys, plug the power cord back in.
4. wait until the screen goes blank before you release those keys.
5. follow on printer instructions.

If that doesn't work, you can try putting 3 different cartridges (oem or refilled) in the printer. I've heard that the printer memorizes only 3 serial numbers, so if you put in 3 cartridges and then the refilled one, it should read it as new. Not hard to do, but not everybody has 4 same cartridges, so that might be a problem.
I have also heard of putting adhesive tape on some contacts on the cartridge, but I do not know on which one you should put the adhesive tape. I know it works for some older models, should work for new ones too. Here is a link, showing the picture of these older cartridges (couldn't find yours). It might help.
