Clearly? Clearly you are wrong. Did you come by this revelation because the original poster reported that bitmaps print black? If so, the black on a bitmap is mostly CMY, damn little, if any, K.
The larger principle is that hardware wears out and breaks. Software is pretty much incapable of wearing out or breaking.
hmm.. seems like deleting the driver and reinstalling worked. i must have been dead wrong
definately not a software error had to have been a hardware problem!!!! nice try bob. chaos68, ignore the rifraf. they think because they have thousands of posts, it makes them correct, and that gives them the right to belittle you when responding. it simply means, that while you and i are working, they are on here doing NOTHING but bolstering their sorry self image. dont worry, you arent the only one that deals with it. if you have any more probs, just hit me up. i can tear my mutoh down in about 2 minutes and have the heads and dampers out and changed in about 5. the printer is suprisingly simple. dont let it get fool you. i was scared to death when i got mine. just dive in, and you will quickly be able to diagnose problems fast. i also have some tech manuals that will keep you from having to hire a tech to do alignments and whatnot if you dont already have them.
and bob, ive spent my entire life as a programmer. clearly youve never spent a single minute other that what you have seen on the discovery channel. software breaks more than hardware.
