Canon G620 Matte Photo Inconsistency

[clee25]

I just bought my G620 printer for few days and I printed the follow image one after another, on the left it was a first time printing on matte sticker paper and right side is the second time, the quality has reduced so much, any reason why? The subsequent prints became very grainy. I couldn't print the same quality anymore. Please help.
