I'm sure the A920 has its own "self test", run it and check results. You needn't be connected to the system. Find out via the Dell support website how that test is initated. The manual if you don't have one is probably .PDF file so be sure to have Adobe Reader available to read it when gotten form Dell support website. Post back with results.
I have been trying to download the drivers and such for my DELL A920 A-I-O printer. I have tried using the download CD and also the download from the DELL site. It will download like it should and I will go through all the routine that it calls for and then all of a sudden I will get a pop-up that says it can't find the printer and will wipe out the download automatically. It tells me to make sure that the USB cord is a good one and installed properly and that the power cord is also good. They both are. I have put 4 different USB cords on. When I turn the printer on I get a flashing light on the power on and off button, which means that something isn't right. I do not have the manual for it. Has anyone got any ideas as to what my problem might be? The only thing I haven't ried it to install it on a different computer. I am running Windows XP home with SP2. I have tried installing with and without my anti-virus and firewalls running.
