This is the Perfectanswer to this woefully terrible printer system failure problem. I've been battling this printer's issues almost daily. All diagnostics and utilities point to everything working properly but somehow my 6700 will print fine on one invoice but magically appear in an "error state" on the next invoice.
My bookkeeper cannot even do her job wihtout having to call me or run through the generic "Hard Reset" to get her next succesful print job completed.
Bottom line: I found a cartridge that needed replacement, so I thank you for your insight.
Shame on you HP
