Thanks for joining the conversation, plainjanea!

So that the Community can help you better, we need to know exactly which Canon printer model you're using within the PIXMA TS6400 series. The model number should appear on the front of the unit at the lower right. That, and any other details you'd like to give will help the Community better understand your issue!

If this is a time-sensitive matter, click HERE search our knowledge base or find additional support options HERE.

Thanks and have a great day!

Hi - I'm having the same problem - just started today when I turned the printer on. I have a Canon PIXMA, TS6400, Series No [redacted], getting Support Code 7700. I've been using the same ink cartridges for a while - (they are not running low) - but it wasn't a Canon Product.

Ink was from ValueToner - compatible with the printer - has been working fine until today

We apologize, however TS6400 is the series, not the printer model. The model will be on the front of the printer or on top, you may need to lift the paper tray to see it. As far as ink is concerned, we can't really troubleshoot 3rd party ink, because we don't know what's in it, the quality, or if it is actually what they say it is.

We'd recommend grabbing Canon ink cartridges to perform a deep cleaning to see if that resolved the issue.

Basically the problem gets created by using a non Canon cartridge. ##CANON provides no support here. Don't expect it!!!! It's a joke.I found I was within my warranty and exchanged for a new one.

We design our inks very specifically for our printers, using high-quality materials so that the print quality is the best it can be, and our printers keep running as smoothly as possible without damaging the print heads or gumming up any of the internal components. Many cheap inks are low quality and leave residue on the components in your printer. This can not only impact the quality of prints, but it can cause the printer to stop working altogether.

Because we don't know what chemicals other manufacturers put in their inks, we cannot and do not support using any ink other than Genuine Canon inks and toners. Canon USA cannot be held responsible or liable for any damages or other losses due to using non-Canon inks and toners. The 1-year limited warranty does not cover physical damage.

Support code 7700 does not enable the cartridge to be changed. When opening the printer, nothing happens (i.e. the ink cartridges remain idle). Please advise

How to fix Canon printer error 7700?

If you've encountered the error code 7700 on your Canon printer, don't worry, there are some solutions you can try to resolve it. We'll explain them below, so please take note of each one and don't skip any:

Restart your printer and computer to clear temporary RAM memory: Sometimes, a simple restart can solve many problems by clearing temporary memory and restoring settings. To restart your printer, simply turn it off, unplug it from the power source, wait a few minutes, and reconnect it. To restart your computer, follow your operating system's instructions. Open the start menu and select the restart option next to the shutdown option. After these procedures, both your computer and printer have their memories cleared. Now, check if the 7700 error code has disappeared.
Check the status of the ink cartridges and replace them if necessary: If you have installed old or incompatible cartridges, it's best to replace them with new and original Canon cartridges. This ensures that your printer recognizes them perfectly, and the ink is of good quality. To change the cartridges, simply open the printer cover, carefully remove the cartridges, and place the new ones in their slots, pressing until you hear a click.
Clean the printhead with your printer's maintenance program: If you have used third-party cartridges or if the printhead is dirty, you can try cleaning it with the program built into your printer. This program performs a deep cleaning of the printhead, removing any residue or obstruction it may have. To access the program, follow the instructions on your printer's screen or consult the user manual. Generally, this option can be found (on Windows) in the devices and printers section. Select your printer model, right-click, go to properties, maintenance tab, and choose the deep cleaning option.
If the problem persists, repeat all the previous steps: Make sure to follow all instructions carefully and not skip any steps. The 7700 error code may be due to a combination of various factors, and you may need to take multiple actions to resolve it. So, don't get discouraged if you haven't solved the problem yet; this issue has a solution, and we will find it.
Take your printer to an authorized Canon service center: If the 7700 error code continues to appear after following all the previous steps, your printer may have a more serious problem that requires a thorough review by a professional. Look for an authorized Canon service center near you and take your printer for an accurate diagnosis.
