Looking for help with our Mutoh 1614. I will try to list step by step what was done to the printer. The initial problem was one complete yellow channel was not printing when doing a nozzle check. We changed the yellow damper, and the same channel still was missing from nozzle check. We called for service, when the tech arrived he put in a new damper and maintenance station and all was well. The next day we printed about 70 lineal ft and noticed yellow ink running out of a hole in the bottom of the printer chassis below the ink cartridges. Removed covers and found ink was coming out around the sub tank area, had saturated the pad underneath and dripped off the edge onto the bottom of the chassis and about a 4-5" puddle under the printer. Called the tech and they said it may be a one time over charge of the sub tank, print some more to see if it continued. We continued printing and after about 6' the printer started printing heavy black from edge to edge of material. Called Tech they came back in and changed head, we printed a 2 foot test print and all looked good. The next day we printed about 10' and the printer started printing the same black from edge to edge. Called tech they came back in and changed head again and a blown fuse on the main board. Tech could not get printer to communicate with computer thru network connection so they replaced the main board. Printed a couple ft and all was well. Next day we printed 10' of material and cancelled job due to banding and the wave pattern marks that came and went in the print. Called tech, we adjusted page feed, started print, this time it printed about 2 ft, started printing heavy black then a 74cr current error. Ripped and sent job again 3 or 4 times with same result except it started doing it after less and less print. Now when we turn on the machine if the carriage is on the capping station it will go thru cleaning cycle then throw a 74cr current error when the carriage passes the middle of the printer during the media initial, or if the head is on the left of the machine when powered up it throws the same error about 2-3 seconds after powered up. Have also replaced the cr motor and we replaced the encoder strip. They are coming in again to change the trailing cables, main board, and cr board. I was hoping someone had an idea that would help. Sorry for the long post tried not to leave out any clues.
