How to refill OEM HP 564, 564XL, 920, 920XL, 934, 935 Cartridges

Follow

This article is for refilling OEM (original HP) cartridges.  If you are trying to use REFILLABLE cartridges, please visit here: https://support.bchtechnologies.com/hc/en-us/articles/203343285

 

There are two Methods to refill your HP cartridges. Please read both methods. Use whichever method you find more suitable.

 

Before you refill the cartridge, you need to turn off the Chip Info on your printer.  The refilled cartridge will NOT show full ink level (more info).  Instead, it will show the cartridge as empty.  Once you turn off the Chip Info, your printer will print forever, so you need to monitor the print quality and add more ink when necessary.

To turn off Chip Info: got to printer's product control panel Setup->Preferences->Chip Info and turn it off.  If your printer doesn't have a LED screen, press and hold the (Wireless) and (Resume) buttons for 3 seconds to turn off and on chip usage information.

-Refill Method A: Top Down-

A HP 564 / 920 cartridge is divided into two chambers. For regular (non-XL) cartridges, the connectors between two chambers are sealed, so you only refill the chamber A. For XL series, two chambers are connected so the cartridge can hold more ink.  Therefore, you can drill a hole on top of "Chamber B" and fill the chamber B with ink (as picture above).

 

  
       
Refill for Regular (non-XL): from vent hole on top of chamber A
       Refill for XL cartridges: from refill hole on top of chamber B

 

Need syringes?  $4.25 for a set of 4 syringes & needles on BCH Website  Want to seal the hole with plugs?  Check out BCH's Refill Plugs (3 mm or 4 mm, depends on how you enlarged the hole).  You can't seal chamber A with plug because you will need air hole.

1)    Place your cartridge(s) on a paper towel or newspaper, an area that may tolerate a spill.

2)    If you still have the cap on your outlet port, secure it with a rubber band. If there is no cap, cover with duct tape, preventing ink from dripping out while you refill.  If you are going to do this often, consider to buy a set of cartridge clips ($2.97-3.45 on BCH Website).

3)    For standard 564 or 920 cartridges, Fill your syringe with 4cc of ink. For 564XL or 920XL, fill your syringe with 8cc of ink.

4)   For regular cartridges:  Try not to remove the manufactured label on the top of the cartridge. Find the vent hole (The first diagram displayed at the top of this page, "Chamber A") with the needle on your syringe. If you cannot locate the vent hole, remove the label. If your needle will not fit into the vent hole, drill the vent hole big enough for your syringe needle to fit inside.

For XL cartridges: drill a hold on top of chamber B.  Some XL cartridges has a refill hole blocked by a plastic ball.  You can use a hand drill to drill through the ball.  Refill the ink and seal the hole airtight. You can use a rubber stopper/plug like this one to seal the refill hole or a dab of glue from a hot glue gun. Because you did not damage the air hole and air channel, you can skip the #8. 

5)    Insert the syringe needle into the vent hole /refill hole (as shown in picture above) all the way down into the cartridge, then pull back half a centimeter.

6)    Slowly inject the ink.

7)    After your needle is empty stop injecting ink. If the ink overflows pull back on the syringe to suck back in the overflowing ink back into the syringe. 

8)    Cover the vent hole with a piece of transparent tape. If you removed the manufactured label, please continue to read. 

9)    Leave the orange cap (cartridge clip or the duct tape) on the outlet port for 1 minute. Give the sponge inside the cartridge enough time to soak up as much ink as possible. Now, find a cup or bowl and remove the orange cap or duct tape from the outlet port and let the cartridge sit for 2 additional minutes. Let any excess ink the sponge cannot hold, drip from the cartridge into the cup or bowl from the outlet port.

     Note for regular (non XL) cartridges: If you removed the label from the cartridge, you need to place a bigger piece of tape on the cartridge. If you leave the vent hole exposed, then ink will flow down and flood your printhead.  However, if you seal the vent hole airtight, then the ink won't come out.  You need to place a piece of tape on the yellow rectangle below (as shown below in diagram) If the ink is not flowing out, pierce a little hole on it with a pin.

10)    After there is no more ink dripping, wipe the outside rim of the outlet port, carefully with a paper towel, and place the cartridge back into your printer. Run a cleaning cycle 1-3 times. Do not run a cleaning cycle more than 3 times.

 

-Refill Method B: Bottom Up-

 

1. Refill Pedestals

 

 

These kits can be found at eBay by searching "564 Pedestal".  The mechanism behind it is very simple: there is a curved tube inside the pedestal (blue line in the picture).  When you inject ink into pedestal, ink is pushed into cartridge from bottom.  These kits runs for about $15-20 on the market.

 

2. Poor Man's Refill Kit

If you have some cartridge clips ($2.97-3.45 on BCH Website), you can make them into refill tools.

Step 1. Make a hole in the center of each silicone pad

Step 2. Enlarge the hole in each clip, with scissors

Step 3. Install silicone pad.  Make sure the syringe tip can fit through clip hole.

Step 4. Fill the syringe with ink.  Inject ink from the clip hole.

3. No Tools Required

1)    Place your cartridge(s) on a paper towel or newspaper, an area that tolerate a spill.

2)    Turn the cartridge upside down, so that the outlet port is facing upward.

3)    For standard 564 or 920, Fill your syringe with 4cc (4ml) of ink.

4)    Drip ink onto felt pad (Do not pierce pad) until ink just sits on top of pad or starts leaking from the vent hole.

5)    After you injected all the ink or the cartridge is leaking, let the cartridge sit for a minute upside down and let the sponge soak up the ink.

6)    Now, find a cup or bowl and let the cartridge sit for 2 additional minutes. Let any excess ink the sponge cannot hold, drip from the cartridge into the cup or bowl from the outlet port.

7)    After there is no more ink dripping, wipe the outside rim of the outlet port, carefully with a paper towel, and place the cartridge back into your printer. Run a cleaning cycle 1-3 times. Do not run a cleaning cycle more than 3 times.
