    Canon iR 7200 E240-002

    Hi everyone,
    Yesterday i got an error message on a Canon iR 7200 - E240-002. If you copy small series 20 to 50 copies, everything works well, but if you start copying larger series etc. 400 copies, the machine makes about 100 copies, and then stops printing. there is no error message on the display yet, it still says printig... and it stays like that for about 10 minutes. After that error message appearson the screen, and the machine restarts all by itsef. When it turns back on, I see that the paper stops in the same place every time. It stops just in front of the registration roller.In service manual it said : replace dc controller or replace main board. Is there any other solution to this problem?
    Thanks in advance.

      most of the time on intermittent e240/ it's the Main Cont pcb-----------


      E240       error code can be caused by excessive side to side movement of the Transfer / Separation Corona Assembly. To resolve this issue, check and make sure the Transfer / Separation fixing latch bracket is properly installed. This is the latch which secures the Transfer / Separation corona assembly.

      Has been noted that the registration clutch can load down the DC Controller and cause an E240 error code. The clutch can spin if the pin holding the clutch is not inserted correctly and damage the registration clutch wire harness. The clutch can also intermittently short out through the clutch housing.
      **Knowledge is time consuming, exhausting and costly for a trained Tech.**

          I've checked the clutch, and transfer/separation corona assembly, it seems to be ok, but i have ordered a new clutch just in case. When I've disconnected and reconnected all connectors on DC controller and Main board, the machine started working fine. That day they made about few thousand copies whithout a single error. But the next day, machine started throwing e240-002 again. Then I cleared DC CON in service mode, and the machine started working fine. They still haven't called till today, so I gues that the machine is working.....but for how long. I'll keep you informed. Thank you teckat for your reply, as allways it was very helpfool.
