so far Bel paper with HP ink no problems what so ever, but I am still on the first pack I purchased 2 yrs ago

I do know for a fact that the inks differ, HP ink is electronicaly charged to work as it does with an HP printer,, the colors, weight ,and viscosity are specific to different brands

all said,,,this indeeed sounds like a paper problem.

let us know what you can, as I've been very happy with Bel so far. but am running low
