I am developing a software to control a machine based on the prepaid user account (with a smart card as an user id). I connected to 4 pin connector (CN211) on the mainboard with an external I/O card (Advantech PCI-1757UP) installed in a PC. The goal is to manage signals on these 4 pins (but it may be not sufficent in this case). I have chosen an "optional keycounter type - keycard" in the service menu.
The user should be able to to make copies as long as there is enough value on his account. I deliver a "zero" signal to the pin 1 of the connector to unblock the copier, when the user has enough funds to start copying. When I detect no or not enough funds on his account during the operation I send a 1 value to the pin 1 of the connector (with a small delay of ~100 ms). I intend to let the paper get out from the tray (and not block the machine).
The problem occurs when a duplex option is chosen by a user. When I block a copier after low value on account detection, the paper sheet is blocked in the duplex unit and the whole process breaks with an error.
The required situation is that the copier ends the process but does not take next papers sheets from the feeder (which leads to blocking the machine). Is there any solution I could employ in this case (no matter, technical or organisational) ?
How to stop the machine without blocking it. In example: user tries to copy 20 pagesin duplex mode but he has money on his account only for ..lets say 11 pages. How to stop the process safely without blocking the machine after 11th page?
