    Hi, purchased a c751ex....ran about 80k on it..blue solids are not solid they have what looks like equal margin roller marks.ran solid tests..only seems to happen on blue...when we have a file that contains solid blue or green 2inch box they show up with noticeable magenta and deletion lines...tech is stumped...should I get a replacement...

    What has the tech tried so far? Is this a trained Ricoh tech? I would probably print solids in each color : cyan , magenta , yellow , and black and see which colors have the defect and start from there. I would think drum, charge , cleaning and maybe laser.

    We have 1 with 2 million on it in 1 years time, probably the most common thing is to make sure cleaning units have been updated, there was a service bulletin out for this as well, maybe your machine all ready has it ?
