Canon Ink Cartridge Troubleshooting (with printhead)

I have inserted my new cartridge(s) into the printer and a message appears telling me the cartridge(s) is empty. The printer refuses to operate and asks me to replace the cartridge(s)
Remanufactured cartridges will always show low or empty ink levels so the message is completely normal.
First you must tell the printer to ignore the ink levels and allow you to print. Follow the steps below:
a)   Insert the cartridge(s) into the print and try to print a document from your computer
b)   Wait until a message appears telling you the cartridge is empty and need to be replaced before you can continue. As shown in figure 0.8
c)   Now hold down the cancel button on your printer for 5 seconds then release (the round button with a diamond shape in the middle). As shown in Figure 0.9
d)   If the message still appears then hold down the cancel button for another 5 seconds

Figure 0.9

The printer will now allow you to continue and print. Please note the ink levels will still show as being low or empty but the printer will now ignore this.
I have inserted one cartridge into my printer and I am receiving an error telling me that the cartridge is missing or faulty?
First check if the cartridge is the correct model for your printer
Take the cartridges out of the printer and make sure all the packaging clips and blue tape covering the copper part of the cartridge has been removed from the cartridge.
Then while the printer is on pull the power cable out the back of the printer and leave the printer off for 15 minutes. Doing this will give your printer chance to clear the error
Take the removed cartridge from the printer and rub the circuitry on the front of the cartridge with a moist tissue as shown in the diagram below making sure the circuitry is completely clean and free of any dust or dirt (figure 1.0)

Turn the printer back on and firmly reinsert the cartridges making sure they are fully clicked into place.

I have inserted both cartridges into the printer at the same time and receive an error message telling me that cartridges are missing or faulty?
First we need to identify which cartridge is causing the problem. If you test your old working black cartridge with the new colour cartridge that we have provided.
Then remove both cartridges and test your old working colour cartridges with the new black cartridge that we have provided. This is illustrated in the image below (figure 1.1)

Once you have identified which cartridge is causing a problem then try cleaning the circuitry on the front of the cartridge as shown previously in figure 1.0

I have inserted my cartridge(s) and the print quality is bad or there is no ink at all appearing on the paper.
This is most often the result of ink not being able to flow from a printhead
Remove the cartridge(s) from the printer and make sure all packaging including the blue printhead tape has been removed.
Fold a piece of damp kitchen tissue (or any other non fibrous tissue) a couple of times and clean the printhead making sure there is no dried ink or dirt on the printhead. For best results make sure the water is warm.

Then sit the cartridge(s) on some moist kitchen roll making sure the bottom on the cartridge (where the ink comes out from) is in contact with the kitchen roll.
Leave the cartridge sitting on the tissue for 20 minutes, and then re-insert the cartridge back into the printer. This is shown in figure 1.2
Now do a few head cleans/Nozzle cleans through the printer software to get the ink flowing

I have just inserted my new cartridge(s) and the ink levels on my computer are showing low or empty.
Remanufactured and compatible cartridges will always show low or empty ink levels because the circuitry on the cartridges cannot be reset. We can assure you that the cartridges are all checked before they are sent out to make sure they are full. Please ignore the ink levels are print as normal.

I am trying to insert the cartridge(s) into my printer but they won’t fit.
First check to make sure you have purchased the correct cartridges for your printer.
Remanufactured and compatible cartridges often do look a slightly different shape but they will fit into the printer the same as the original cartridges.
If the cartridge(s) still won’t fit then make sure you are placing the cartridge into the correct slot.
Please note that ‘photo’ cartridges fit into the black slot to replace the black cartridge and must have a working colour cartridge in the printer at the same time

The cartridge appears to be running low sooner than it should based on factory page yield estimates.
Factory page yield estimates are based on average 5% text/graphics coverage on the page. If you are printing graphics or heavy text applications, coverage will be more than 5%. For example, if you coverage is 10%, your cartridge will run out in half the number of pages specified in the factory page yield
Below is a couple of examples with different fonts and spacing of what 5% coverage of a page looks like.

As you can see this coverage does not necessarily represent a typical print for an average user. So it is worth keeping in mind the page yield listed for your cartridge does not necessarily mean you will get that many pages from your cartridge.
How many prints you get out of your cartridge will depend on a number of factors including Size of font you use, Size of font you use, Weight of font you use, Width of page border, and Addition of extras such as graphs, images or simple lines
