Can someone provide some tips for refilling the HP 57 and HP 28 .. I'm having problems filling these types.. It says each color takes 5cc but the magenta keeps over flowing. I'm filling under a vacuum and manual filling. Each time I fill manual I have poor print results. An on my Select jet I cannot configure my ink lines to distribute different ink levels so I just looking for some new ideas.
