[PRODIG] Straight or flat steps in 1290 nozzel checks

[Jay Myrdal]

I ment to post this to this here (prodig list).  There is also a copy on the aop list (sorry aop-list mom) I mixed up the messages.     I am getting nozzle checks on my 1290 which look perfect at first but on close examination the steps, while all present, are not all offset the same.  some of them are more or less extensions of the previous step like a double wide flat step or sometimes like a half step.  This effect seems to move around and is not always on the same nozzle or colour. What causes it? How serious is it (especially when printing profile patches)? How do I fix it? Thanks Jay ..   http://www.myrdal.com
