To Hpnetserver,
This is somewhat new to me-------and exactly 100% different from my experience.
Which I posted in early Febuary--with many responding to that thread and the thread started by Ghostbear.
Maybe my experience is not that extensive but this happened with 9 out of 9 virgin Hobbicolor blanks and quite a number of depleted Canon OEM cartridges.
But before I go into more detail, let me point out that in a non defective ink tank type cartridge for a Canon, there are exactly four controls a user has over the refilling process------those controls are how much ink is injected, the open closed state of the air vent, the open closed state of the ink inlet hole, and time. So if you are getting only a partially saturated sponge, and I and other users are getting a 100% saturated sponge, one or more of these variables must be different.
Exactly like you, I followed instructions and injected an initial 8 cc of ink into the reserve tank of a virgin hobbicolor cartridge---with air vent open, ink inlet hole open, and after a minute or so the reserve tank almost totally emptied and the sponge 100% color infused. Then I taped over the air vent, injected another 6 cc of ink into the reserve tank which filled the reserve tank to about 80% and sealed the ink inlet hole with the screw. This happened with nine out of nine cartridges. Unlike you, I experienced no banding.
But I was left wondering about the air vent--so when I decided to refill some depleted Canon OEM cartridges, I decided to experiment. After creating an ink inlet hole with a screw and o-ring seal, I did the following-----I only injected six cc of ink into the reserve tank and watched the sponge drink up the ink--when after 15 seconds or so--the sponge was about 70% color infused --I immediately taped over the air inlet hole----which did exactly nothing-----the sponge kept absorbing ink until it was 100% color infused. Yet you say that taping over the air inlet hole should stop further sponge absortion---I found that not to be the case--and this happened every time with depleted Canon OEM cartridges. Which leads me to ask
if the state of your ink inlet hole is different from the state of my ink inlet hole in your proseidure? My ink inlet hole was open to air during the entire process--could you be sealing the air vent and the ink inlet hole at the same time ?--which might then account for your sponge not becoming 100% color infused.
Or perhaps is your timing different-----I note the grandad35 responce is that he injects the whole 11 cc at once and then rapidly seals the ink inlet hole--15 seconds in out done. And grandad35 also seemed to note he got 100% sponge color infusion.--while I am using a leisurely three minutes with the ink inlet hole open.
And to Mccoady----I should note exactly zero of my nine virgin hobbicolor cartridges showed wild ink dripping from the ink outlet hole. But my depleted canon yellow cartridge sure did--even though the ink outlet hole was capped. And
the dripping was copious and non stop until the ink inlet hole was sealed--at which point the dripping stopped fairly rapidly----even giving the cartridge sides a squeeze did not induce more than a fleeting set of drips after the ink inlet hole was sealed. I do not know if I should be wary of using that cartridge or not--but I can sure understand anyone being disturbed by the mess.
But as I previously mentioned, I had posted this difference between the hobbicolor instructions and observed experience over two months ago---to date Hpnetserver is the only one to date to post that the instructions have a basis in reality--so I am eagar to hear where our methods differ--because Hpnetservers method could well be better.
