42:03 Error, already replaced motor and mechboard... still not working

#1 KmetzCo 3 years ago

Hello, i have the HP360 and one day while printing, my job finished. I went to start a 2nd run of the same file and i got the 42:10 error.. sounded like the printhead dropped down and it said scan axis error. I looked for anything in the way and nothing. Eventually i got to where i was told to purchase a new axis motor.. so 400 something dollars later.. it arrived, i had a former HP tech come out and install it. Turned it on and exactly same issue.. nothing changed... so he said it must be the Mech Board.. so i go and ordered that for almost 500 bucks and when that arrived, i called the tech and he came out and put that in. It then worked for about 10 mins.. it did the full restart and everything.. he told me when it was set, to lube the rail and do a little tuneup. So i did that, i went through the process, it moved back and forth, everything good.. then i went to install media and bamm.. same error again.. not we're right back in the same spot almost 1k later.. this is frustrating with jobs pending and no real solution that i can tell. Any ideas or suggestions?

Hi @KmetzCo, Knowing only the service error that you are facing and after the replacement of the parts affected, the best solution will be to contact your support representative to investigate the issue. The only thing I could recommend is to check the cables and parts related to the problem to see if there is a possible misconnection.

I entered diagnostic menu during boot up.. i went to scan axis test and it works fine during that test right up to 'the end' then the same error. It slowly goes left to right, then fast, then at what looks like the last step, it stops.. Also I did the check substrate for jam, moved it up and down, all good.. i did voltage test on carriage, all was fine, etc. I did notice this (see video) are these black stripes tape or sensor? This one is torn

It could be your encoder strip and/or encoder strip sensor. If it is not the motor, then usually the encoder is at fault for that code. Hope that helps and good luck.

Hello All! I hope those in this string previously have resolved their issues. My company's Latex 365 had the same one, and after lots of troubleshooting I am here to share our findings. We got the same 42:03 error regarding "ServoMotor/Carriage current limit!" while booting up the machine. It would get to ~25% initialization, the carriage would jerk, a loud clonk, and the error would show. This was a second-hand Latex 365, low hours and tested fine. Worked for a week, then threw that error. Went away after restarting the printer a couple times. Then came back but didn't go away. Swapped carriage motors from a retired 360, problem went away. Error came back, then went away for a while. Finally, it came back and refused to leave. We swapped the control board located behind the secondary power supply (the CIES PRINTMECH PCB02), no luck. We swapped the secondary power supply, no luck. We cleaned the encoder strip, no luck. Baffled, we took the night off. Our last attempt was to clean or replace the encoder sensor. After cleaning the sensor and placing it back in (did not swap it), the printer worked!! I could not find a guide or answer anywhere, so I hope those with this issue find this helpful. Here are steps for cleaning the encoder sensor (please take care while working on this printer, the ribbon cables, plastic tabs, and many components are fragile!) -Turn printer off, remove right side end cover, and move carriage to right side so is easily accessible -Remove metal shroud (kind of a pinching motion to un latch it, no screws) -Unplug two connectors from top of board (power and data, I recommend removing the plastic shroud that covers the wires to give you more space to work) -Pivot the top of the PCB toward the front the machine, pushing in the plastic tabs that retain it -Underneath the PCB near the bottom right corner, the sensor is held in place with one small torx screw. Unscrew, remove cover, and use needle nose pliers to carefully pull sensor out -NOTE: I did not unplug the sensor's ribbon cable from the board, I had enough room to clean it without doing so, but you may need to -Using a compressed air duster can, I gently blew into the sensor (looks like an upside down U) from various angles. I then gently rubbed a lint free cloth thru it, then blew it again -Re install sensor, place cover back, screw in, pivot PCB back till it latches, plug connectors back in, put plastic shround back on, reinstall metal shroud (make sure it is snug) -Hopefully that fixed it! Also, we used the Diagnostic menu (like mentioned above) to test the carriage motion, and it error-ed at the end, very similar to Kmetz (until cleaning the sensor). To enter the Diag menu from a cold start, there is a YouTube video titled "HOW TO ENTER THE DIAGNOSTIC MENU ON HP LATEX 360 PRINTER", which worked for me. Please feel free to reach out with questions to my email, we were stumped and could not find help online,, so I hope this helps! Reach me at avi@sign-it.com
