Digital BW, The Print

If you have done repeated head cleanings and still get incomplete
nozzle checks with segments skipping, try cleaning off the wiper
blade, located to the left of the parking station pads. When using
pigmented inks, there tends to be quite a bit of pigment buildup on
the wiper blade, so cleaning with a wet paper towel periodically helps
this situation.

Remember, this printer was designed to work with dye inks, which do
not build up on the wiper blade and parking pads, like pigmented inks do.
