I sourced a surplus 9900 that sat for a while but printed an ok color nozzle check sans the yellow channel. I installed Cone carts with flush and did an initial fill. The right side waste tank overflowed even thought the display indicated it was fine (lucky for me I have medical ‘chucks’ on the floor beneath the printer.) I let the printer sit for a few days with the flush and did a nozzle check.
Yellow channel was back but the green was not so good. I did a cleaning and started having problems like Mark and Douglas.
Today I reset the chip on the right tank since it was displaying near full. I did a paired channel to clean the absent green and poor orange. I am now getting an intermittent fatal error A139. I figure its soon to be permanent. I can boot into maintenance fine, cleared the ink parameters but no joy. Error was still there. I am letting the printer sit sans any power for now.
Any ideas ? Who do you recommend for service in the NYC met area ?
