Question about HP DesignJet 450c InkJet Printer
After turning on the unit the data and media light come on. I can press a button and get the ready light to come on. If I try to load the roll paper it goes fine untill it trimes the sheet. Then it backout the paper and the media light flashes. I cleanded a lage amout of ink off the sensor on the carrage assembly. The service manual suggest replacing the carrage assembly after checking the trailing cable. HP support suggested the system board.
The sad part unfortunatly is that the sensor on the carrage is below minimum specification. The only solution is to change the carrage as a unit P/N C4713-60039 and its going to be expensive. Normally the carrage belt would be replaced at the same time.
