My TS9120 ink leaking internally and on the output tray. This just started happening recently after I replaced the black in cartridges. I thought maybe I had bad cartridges so I replaced all the cartridges with new. I always use genuine Canon ink cartridges. Leak appears to be worse. Ink ends up on the back side of the printed page. Ink is also accumulating (puddles) on the output tray. Photos showing a lot of ink on the internals of the printer from what I can see inside the printer. TS9120 Ink Leak

I have to concur with Shadowsports, the maintenance for an ink leak is very simple but you appear to have a lot of it in the workings of your printer.
Cartridge Problems: Ink leaks often occur due to faulty or improperly installed cartridges. If the cartridges are not seated correctly, they may leak ink.
Clogged Nozzles: Blockages in the printhead can cause ink to back up and leak. Regular maintenance can help prevent this issue.
Damaged Cartridges: Inspect cartridges for any visible damage or defects. A damaged cartridge can lead to leaks.

Thanks all for the input. I'll see if Canon support can help. The printer is 7 years old but works fine except for the recent leak development.
