We have a WorkCentre 7435 and have recently enabled Follow You printing using Secure Access.
For some reason, some (only some) users have quite a bit of difficulty getting the "Print" onscreen button to respond to their touch. Some users stand there, pressing the screen repeatedly with little result.
We also have a WorkCentre 7328 that seems to respond a little bit differently. Perhaps slightly faster to respond to a touch but I haven't had an issue with the 7435 not responding.
I've looked in the documentation but haven't been able to find anything regarding a setting to increase the sensitivity of the screen. Perhaps it's not something that is adjustable. Like I said, I don't have a problem with either machine...
Apologies in advance for the obscure question, and the equally obscure problem.
