This is in addition to my post "IB to Ob lines " posted earlier.
Most of my issues seems sorted out but now i get intermittent ib to ob lines in cyan. and each time it happens i get a big dot on cyan drum . after that the frequency of cyan line increases .There is no specific interval for the line to appear. Seen mostly when i give single print. When i give multiple prints in a single job the frequency of lines appearing is greatly reduced.
any suggestions greatly appreciated
