I have had this happen before but can't remember the fix! I found it on the internet but can't seem to this time. I have a C7280 all-in-one and after finally resolving the dreaded "ink system failure" error code, it now acts like it is printing but only puts out blank pages. Does not give any error code. Removed and reinstalled drivers. Tickled it, fondled it, spanked it and burped it! As I recall from before, the fix involved something to do with a coffee filter but that's all I remember! Any help would be greatly appreciated!
I am running 32 bit windows7.
