We have been running an R1000 for a month. We have issues where the prints are coming out short on the length. started out 1/16" now HP has gotten it back to 1/32" on most rigid substrates. Control IJ40 is coming up a full 1/8" short on the length. I've had HP send two different techs out, and they can't figure it out. After 3.5 weeks we are hearing from them that the machine is printing within tolerance! Is anyone else experiencing this? How a wrong size print be acceptable? They have messed with heat settings feed calibrations on the service side, and it's still not working. I've had a file I printed sent to our supplier, they printed through Onyx and Caldera and were off 1/16" through both software. HP in Atlanta printed through Caldera and it was right on.
I haven't ever seen this. Every machine I have been working on prints just about 1:1 what it's supposed to be. I guess there can always be small differences but not something like that.
So if you print a ACM, the image always comes out shorter than it's supposed to? It should band the image/if you have text that should not have perfect focus, right?
I can only imagine it to be OMAS problem because that is the only thing messing with the feed.
First clean the lens of the omas. It's on the home side under the belt. You don't need to take it out, just lift the belt a little.
Then you can't run it but I would definately want to run diagnostic
50012 - Check OMAS navigability
Based on that there is other calibrations that I'm not sure if have been done (Correctly).
50011 - OMAS navigability calibration
41006 - Media advance calibration I: (phase and amplitude)
41013 - Media advance calibration II: (slope factor and pixel size)
OMAS:
