I cannot use my Cannon TR4520 printer anymore

Hello, thank you for using Howly.
Would you be so kind to tell me more about that issue with the Canon printer?


Customer Replay

When I now try to print, it says on the printer that it needs repair.

Does it give any specific error message?

Customer Replay

It says to unplug the device and contact the service center- Support Code 7700

What troubleshooting have you done so far?

Customer Replay

I usually print from Copy 2 of Cannon TR 4520 because Copy 1 is not connected. But all of a sudden the icon for Copy 2 is no longer there and the message says I need to repair the printer.
I have tried to print from Copy 1 to no avail.

Error 7700 is displayed by a 2 cartridge printer model after cartridge replacement or after an ink has ran out. It may also happen with brand new printers if using old ink cartridges in them.
The solution to this issue is to replace the cartridges on the printer with Canon branded cartridges, beginning with the cartridge the last replaced before the error started to occur.

Customer Replay

I have had a difficult time finding Cannon Branded cartridges and have had to settle for alternatives.

This could be the source of the issue, unfortunately

Customer Replay

Okay- I will try that.

Customer Replay

Thanks, I hope that works!
