Hi - I was shocked that in under 3 months, mine will no longer power on. I did an internet search, and apparently this particular problem is very clearly described - offered 2 workarounds - neither worked - now I have to take my time to find and have it repaired....even if still under warranty, you don't expect a problem like this so soon with a new printer. Very disappointed.
My old Brother laser printer finally failed after years of good service and I find inkjet models too slow and costly for just monochrome needs. The nice feature is that using the USB for my desktop does NOT prevent printing over wifi. (No CAT5 socket on this model). All the network enabled inkjet ones I've worked with shut off USB if either wired or wifi network is configured.
