You all seem to be refilling your cartridges without a hitch. Maybe someone can be of assistance.
I have a Canon i560, and following the instructions I;
Cover the exit hole,
Drill to create a fill hole,
Insert the needle and fill.
Then place the small black plug firmly in fill hole.
I cannot get the plug to fit tight enough to be airtight. It looks like the provided drill is slightly larger than the provided plugs.
The only way I can get the plug to be airtight is to cover it with a blob of household Goop sealant – not first prize.
Anyone else experience this problem?
