just read this:

I wish I had a dollar for the many times I have received a call from a customer stating I changed my printheads and now I cant print nothing, it goes through the motions but no ink is coming out...
Usually when I hear that they changed their own printheads and now have a problem, I ask, "Did you not only turn the power off but unplug the printer and cycle the power button a couple of times." Then I get the big lie of yes I did that. So when we confirm their is ink in the dmapers and we have ink flow..I have them check the fuses on the mainboard with a alligator clip, once the printer starts prining again, I then say, now tell me the truth, did you actually unplug the power cord before you changed the heads..once I prove that it was their mess up, they then come clean. As you know, its hard to fool a true technician. In my opinion a true technician can troubleshoot just about any problem and know the symptoms of what happens to cause the problems they are having. I have been doing repairs and troubleshooting 5 years and I am still amazed at end-users. Sometimes you have to let peoplpe find out on their own that there is more to repairing than just changing a part.
As for your in house testing before selling, I am so glad to hear that you do that.
YES WE DID UNPLUG AND CYCLE THE POWER ON AND OFF SEVERAL TIMES BEFORE STARTING THE SWITCH
So how do I check the fuse? Where is it?
