Black ink backflowing into color cartriges

dflammer — Tue, 22 Oct 2019 18:46:10 GMT

My IP4000 printer black ink is backflowing into all 3 color cartridges. Has anyone else ever have this happen? How did you resolve it? I'm cleaning the print head now. I'll dry out overnight and put new cartridges in to test tomorrow.

Hi dflammer.

This issue can happen if the cartridges are inserted into the incorrect slot. Please verify that the cartridges are seated in the order that they appear in the image below:

BCI-6 Black
BCI-3e Black
BCI-6 Yellow
BCI-6 Magenta
BCI-6 Cyan

Were you able to test the machine with the new cartridges?

New cartridges inserted in the correct order, same result.

Hi dflammer,

Since the ink is in the correct order and the ink is still backflowing, there may be a issue with the print head. I would normally advise that you get the printer serviced but the IP4000 has been retired and service/parts are no longer available.

You would qualify for the Canon Upgrade Program.This is for out of warranty units which have been diagnosed to require service or are incompatible with a new or upgraded system.
