Canon imagePROGRAF W6400 leaking problem! Can be fixed without replays anything?

SOURCE: Re:Canon Multipass C3500ex

Don, have you unplugged the printer for a few minutes? first the power plug, see if that clears it. If not, unplug it from the computer, reboot the computer, then plug printer back in. If not that,when an ink cartridge is refilled (depending on the model) the printer needs to be tricked into thinking a "new" cartidge is being installed. They make their money from the ink, not as much the printer. You may need to check the owners manual to see if the is the case. I have had to use tape to block off certain contacts, then remove the cartidge and block off another section of contacts, then remove tape all together and re-insert the cartridge.

The ink cartridges are not installed [1401], or a non-supported ink cartridge is installed [1485], or the ink cartridges are not installed properly [1687].
Check if supported ink tank(s) is installed, and re-install them properly, and then close the scanning unit.

you need to enter a service mode before the error message pops up. hold down paper source button + online.
that should override the message before it pops up.
go to replace print head selection. or do a clean. it may still be working. let me know if this doesn't work....but at least you can still get past the message now! marty
