Yes, the head carrier is not made to carry high loading by the seals. Don't permanently distort the carrier. I imagine bad things can happen. Try the grease seal before the oversized grommets.
I can confirm this quite explicitly... Having put a couple of the replacement silicon grommets in a number of printers I've pretty much pushed at least one maybe two printheads beyond their tolerances.mikling said:Yes, the head carrier is not made to carry high loading by the seals.

I'm more than a little surprised that you've been sent the old style of silicon replacement pad as the review kit they sent me was one that included the newer thin silicon pads so I naturally assumed that the seller had realised it was time to move on.canonfodder said:This system is shipped with the now dreaded "replacement silicone seal pads". The pads are translucent and not foam. They seem to be of a fairly low Durometer, and my guess would be around 20 to 30. The instructions say the replacement pads are "to overcome the slight design fault in Canon printers. In short it prevents air getting between the cartridge and print head.(due to Canon's raised print heads)."
So with all the discussion of the seal pads in the thread, I am wondering just what to do. I am leaning toward leaving the original seals in place but adding Grandad35's suggested vacuum grease below and on top. Before proceeding, I plan to do some measuring of the original pads and the replacement silicone pads supplied.
Thankyou, thankyou, THANKYOU!!Grandad35 said:1. It is a common industrial practice to use a "vacuum grease" (e.g. http://www.coleparmer.com/catalog/product_view.asp?sku=7975130) to get a tight vacuum seal in situations like this. Google for a source of this grease in your area, but be aware that this silicone grease is sticky and is difficult to clean up (which is why it is so good at sealing a vacuum). Given that you will not be removing your carts very often, this should not be a problem as long as you are careful and only apply a thin coating. I would put a little under the rubber grommet to seal the inside of the grommet to the ink pickup, then apply a thin coat on top of the grommet to seal the grommet to the bottom of the cart.
