A profile shouldnít cause an issue like this, unless there is an underlying issue with the data of the file itself ... i.e. the checkerboard is actually in the file as a result of processing but just isnít visible until certain color transforms (such as a printer profile) is applied. But I see this as extremely unlikely.
Iíve not used an r2880, but things like head alignments or other mechanical problems seem a more logical cause.
I agree with Wayne, modulo the fact that bad profiles can sometimes hugely amplify small variations in an image. But you didn't make the profile yourself, right? . Can you use the Advanced B&W (ABW) settings to take the ICC profile out of the picture? I'm not sure why you're printing a B&W image with a color profile in the first place. The R2880 driver supports ABW mode, doesn't it?
