I’m having an odd issue with my 9900 after having just replaced the dampers and pump cap assembly this past Friday. The installation of those two things took most of the afternoon (first timer), but went smoothly using the Service Manual as a guide. Following the instructions of the manual, I started the printer in serviceman mode after it was buttoned back up, and cleared the counters. Honestly, I was assuming that the menu setting would lead me to a menu to select a specific counter to clear, but instead it seems to have more or less done a factory reset on the printer - printer started up, ran an init fill, and printed a perfect nozzle check. I was bummed about the ink loss, but happy to see the printer back online.
Now whenever i run a print, the printer will run without any fuss but will kind of freeze as soon as the print finishes - the head scans back and forth like it’s checking for paper size/skew, and then immediately sends a warning to the panel “Code D17E Power Off and then On. If this Doesn’t Work, Note the Code and Call for Service”. The printer restarts just fine every time so far, but always throws the code after running a print after the head scans back and forth for about 30 seconds.
To my surprise, there is no mention of code D17E in the manual, and there is very little information to be found on the internet. The information I did find was all over the place - some say it’s a generic error that could be either hardware or software, some say it’s a network error (the printer is connected via ethernet), and some say it is a problem with the main board. I have uninstalled and reinstalled the print driver, added and removed the printer from the network, updated the firmware to the most recent version, and the error persists.
Has anybody come across this error? I haven’t had time to open the printer back up and check all of my connections, but I feel like I was pretty thorough, and would be surprised (albeit for no real reason) that the printer would boot up and run a print if a connection was bad or missing. The fact that the head passes back and forth over the edge of the paper before crashing out leads me to believe that it’s some kind of sensor issue, and looking at the wiring diagram I do see a few sensors coming off of Sub Board Assy B (which if I’m not mistaken, is the board that plugs into the pump cap assy). My biggest fear is that by clearing the counters in Serviceman Mode that I nuked something I shouldn’t have - I thought for sure it was going to bring me to another submenu, but as soon as I hit the right arrow it just launched into doing its thing and I didn’t dare stop it.
Any help or ideas would be immensely appreciated. I was very deliberate and careful with the job, and can’t think of any “oops” moments that could have shorted a board, but who knows. I did have the thought to try and run a print from another computer via usb, but haven’t had time yet and honestly It doesn’t seem like the connection is the issue. Any other ideas?
Thanks a million.
