Title: Canon IPF 8400 Air in tubing
Post by: MarcTetreault on September 21, 2017, 11:27:36 am

Hi, there is a lot of air in ink pipes towards printheads (long sections without ink).
How do I remove them? Ole inkjet printers came with a portable electric vacuuming device.

I cleaned printheads and still it says change printheads (not old).

We had air bubbles (maybe 1.5 inch) in a few lines - our dealer sent new heads. As your's are not old, might be worth taking them out and in again (changing them with themselves), and seeing if the head (re)install fixes the problem?

Or if the heads are under a year old, then they should still be under warranty from Canon.
