Using EPS refillable edible ink cartridges and filling them with EPS edible ink tends to be more economical than purchasing ready filled cartridges especially if you’re printing large volumes of cake toppers or cupcake toppers.

  • Firstly ensure you purchase the correct EPS refillable edible cartridges for your printer.
  • The most popular refillable EPS edible cartridges are the PGI550/CLI551 which are suitable for the Canon IX6850 and Canon IP7520 printers or the 570 / 571 cartridges for Canon printers TS5050 and TS5051.
  • To fill your cartridges follow the instructions below carefully ensuring you wear protective/ sterile gloves before you start.
  1. IMPORTANT – before refilling make sure your cartridges are in the orange cradles (otherwise the ink will drip from the bottom of the cartridge) and DO NOT try to refill your cartridges whilst in your printer. Always return them to the orange cradle.
  2. Remove the yellow pull tape
  3. Remove the coloured plug and fill the edible ink through this refill port by using a clean syringe and needle. Ensure you use a quality edible ink to prevent damage to your printheads. EPS edible ink has been specially formulated to prolong the life of your printheads.
  4. Fill the cartridge – ensuring the sponge is completely soaked and the cavity is 3/4 full . Remember it is always better to under-fill rather than to over-fill edible ink cartridges to avoid leaking. EPS cartridges come with auto-resettable chips allowing unlimited edible refills. However, after many refills the cartridge outlet may wear out and the cartridges should be replaced.
  5. After filling, re-insert the coloured plugs into the top of the cartridges before you install them into your printer
  6. If the ink isn’t soaking into the sponge, remove the yellow pull strip / tape

How to install your EPS cartridges

1. Remove the pull-tab on the top of the cartridge that says “PULL”. This exposes a small breathing hole that the cartridge needs in order to function. Remember that edible cartridges need enough air so that the edible ink can be adequately dispersed through the edible printer by the printhead. If you press on the pad underneath the cartridge with a tissue, ink should come out of the cartridge. If it doesn’t, you may need to pierce the breathe hole with a sterile pin / needle.

2. Carefully remove the orange bar from the bottom of the cartridge to expose the outlet port for the ink.

3. The cartridge is now ready to be installed into your printer. Make sure the cartridge “clicks” into place by pushing it down into its corresponding slot.You may need to gently pull the lever at the front of the cartridge forward slightly to ensure it fits properly.

To maintain the best quality and prevent print head clogging, we recommend turning your printer OFF and then back ON every day it is not in use, or if it’s not going to be used for a length of time we recommend removing the ink cartridges and carrying out a printhead clean as per the instructions below:

Edible inks are made with water-based food colouring, they include sugar and colour. If you leave the printer idle for too long the liquid from the cartridges may evaporate slightly, leaving behind deposits which can crystallise and clog up your printer print heads. By turning your printer on and then off once a day, your printer will do a cleaning cycle and keeps the inks flowing through the print-heads, preventing clogs.
