Canon IR7095 error

[Caba888]

Copier iR7095 has a problem. The problem that manifests when opening and closing the front door or the manual feeder, the machine remains blocked after doors are closed. After a while (30 seconds or little more), the machine ejects error E733 - 0001 and stay blocked. The only way that the device is up and running to get off and on again. While the door is closed, the device is operating normally. Any solutions or advice what I should check?
