We have an HP310 latex printer and it has light blue spindles that insert into the cardboard media roll.  Ours have broken and need to be replaced.  Our designer spent a couple of hours on the phone with HP this morning and was told by one person that we have to buy the entire roll assembly (>$500) then was given a part number by someone else that turned out to only be for the 330.  He is pulling his hair out trying to get an answer from HP and I told him I would put this out to the good people of Signs101 for some input.  Has anyone else figured out a way to source this piece?  I appreciate the help!
