First, let me thank those who have taken the time to offer advice and solutions.
The list of problems that I have experienced may assist in determining the best course of action for repair. My partner and I are at a point where we are considering sending the unit to a facility for complete refurbishment. I have the capacity to diagnose and repair many of the issues that these machines encounter, just not a great deal of time (and my patience is wearing a bit as well). My partner is a network engineer and quite proficient with any computer program that we have encountered.
We purchased the unit from Ebay 1 year ago. The unit had been refurbished from SWF Mesa, yet I do not have the records as to what was performed because it was prior to our purchase. I can honestly say that all of the errors are rookie errors and not the fault of the machine. Being a newbie, we are truly learning with each step. I had an ink draw problem from day one, but that has been resolved. I have had to replace several printer heads due to clogging and corrosion at the printer cable. Several printer cables due to getting liquid on them and them shorting out. The printer carriage is the result of the tabs breaking that the print head retainer screws thread into. There were error lights on that remained on when I used an oversized screw to retain the print head with the retainer. The lights would go off when the retainer was not used and the print head just sat in the carriage. I assumed there was some sort of sensor that sat in the carriage, or printhead, that indicated that the printhead was in the proper place. After replacing the the print head carriage, now we have the power issue. I do not see anything that is burned on the power supply board after visual inspection of both the top and underside of the board. I'd prefer not to throw parts at the unit. I'd also not prefer to waste a great deal of money by putting it in the hands of a company who will overcharge me for parts and labor. Any further suggestions? Thanks you in advance!
