here is well explained SMEMA interface http://www.daghee.com/?p=326 so, disconnect printer from upline modules and check are any 2 of 4 pins shortened(should be pins No 1 & 2) while machine is ready state. when machine is in busy state the same pin

board input sensor sensitivity? maybe conveyor movement triggers it and because of that it sends pulse. conveyor moves few millimeters, how does machine act?

that sounds like bad relay or relay control. are you in position to check it on relay pins? I would go from there.

Hi, my 2cent.. u could try to check the sensibility of the camera board stop sensor.. maybe it detect something i.e support block.. do reply when u found the actual root cause.. thanks..

Switched out the mech. relay on the board loader, no change. Same behavior. Could not find a mech. relay on the printer... SMEMA wiring appears go directly to a PCB. And it is at that point that I run out of talent. If the machine weren't dedicate

Hi Ariss_T, Thanks! I actually did check that...that was one of my first thoughts as well. While in the I/O, I slide a raw board back and forth under the camera/sensor and it acted appropriately. I will definitely update this thread as new informa

Thanks for the reply. When you hit start on the printer, you can see it send the "start cycle (SMEMA)" signal, and it immediately goes to "awaiting board from upstream." This tells me that the printer knows a signal has definitely been sent and rece

Thanks for the link, Ive actually always wanted to learn Italian :) Unfortunately, because this has been an issue for about 2 weeks now, I think Ive read almost everything ever written about SMEMA protocol. The process seems so simple, it's killing m

Our MPM Up2000 HIE is having a communication problem with any upstream machine we place in front of it...i.e. conveyor, board loader, etc. It all started when we removed a conveyor from inbetween it and a board loader, and hooked those machines up di

On AP machines it is possible to mount the camera 180 degrees out. Not sure if this can happen on Accuflex.
