Refilling Canon PG-540 & PG-540XL Black Ink Cartridges

Refilling Canon PG-540 & PG-540XL Black Ink Cartridges

PG-540 Refill PositionsFor these cartridges we recommend injecting the following amount of black ink:

PG-540/5525B005AA: 12ml
PG-540XL/5222B005AA: 22ml

The fill holes of these cartridges are very small and you will have trouble getting a regular syringe to fit. I recommend using the tool provided with many refill kits, a 2mm drill bit or a square shafted awl to widen it.

We recommend sticking to the lower fill for the PG-540 as these cartridges have a smaller sponge and are physically restricted inside the cartridge. As such over filling them can result in ink spilling inside your printer.

Once this cartridge has been refilled your printer will retain the same ink level estimate it has previously. These cartridges have no way of knowing that they now contain fresh ink and only estimate ink levels based upon how much printing had been done previously. Eventually your printer will believe that the cartridge is completely empty and prevent you from printing until a small prompt has been given. More information on this topic can be found here.

This guide is intended purely to show where to inject the ink into these cartridges and how much we recommend using. For full refill instructions for these cartridges please click here.

    I have refilled my PG540-L Black cartridge but have had no low prompt and have had no results from pressing reset button on my PIXMA model. When I refilled I put the needle through the resistance the full length of the needle , Have I damaged the cartridge by doing that do you think? John

  10. ulf røgeberg

    Hi, after refilling my 540XLL cartridge on the MG3150 printer, I still get the message E-1-6 indicating that I am out of ink. Any sugestions?

    1. RefreshCarts

      It is normal for your cartridge to still believe it is empty when following this guide. More information on bypassing the message in question can be found here: http://www.refreshcartridges.co.uk/igloo/the-infa

  11. Indirah

    I have just refilled my PG-540 & CL-541 cartridges for my Canon PIXMA MX475.

    It is obviously still telling me that my ink is running low. I have searched the internet but have yet to find a solution on how to fix this.

    Can you help me please?
