This has become a constant point of frustration for the last year or more. I don't use the printer often but it seems each time I do I can expect to spend at least a hour troubleshooting something. Usually I get the 3-flash error that would suggest one of the covers is open or there is a paper jam. I have gone through the checklist of covers and there is no paper jam but yet the 3-flashes persist and I cannot print. I am ready to throw this piece of crap out the window. Please give me a clue what I need to do to avoid this nightmare every time I use this printer.
