    1357ex Pro - Constant Functional Problems (SC495)

    We have 2 1357ex Pro's here but one of them is giving me no end of grief. Count is about 3.5mill and for the last 4 or 5 months we have periods where it just keeps throwing up a functional problems screen (no error code). The engineer doesn't seem sure what the problem is and just and just plugs and unplugs connectors and cleans things out (his words). It then seems to be fine for a while. We've probably had 8 service calls for this problem over the time. I'd guess we get something like 70k between the issues.

    For example, I have a 12000 run to do. It did 8000 with no major problems but now will only print c150 copies before it errors. As far as I can tell the underlying error code is SC495 (from the data log).

    Does any one have any idea what the long term solution might be? I can't keep calling them out every month cause it's killing my production capacity.

    Thanks

    Michael

    This is straight from the service manual ! Your tech should also look at TSB B234-12 for this issue. Most of the time when I get involved with this as ongoing, it's because the tech did not troubleshoot it correctly or they don't understand the toner system in these machines.

    Thanks for the reply Tonerbomb, I'll get him to check that if he hasn't. Would we have quality issues with those problems?

    Well that's strange then because the print quality is absolutely fine.

    I would check firmware version make sure its up to date, then check the toner tubes and pump as well as the end sensor. If quality is fine and it throws the code i would guess firmware could be an easy culprit, you know how that goes a machine can run for years with its current version then out of the blue start doing something that was fixed later with firmware update.

    Intermittent problem could be a toner out sensor on the toner hopper starting to go bad. One way to test is to swap the toner hoppers only between the two machines and see if the problem moves.

    Change SP 5875-001 to 1 and reboot. Afterwards, the machine will display the SC every time instead of the reboot message.

    This issue is usually sorted by cleaning the toner lines and cylinder completely, being careful not to damage the toner detect sensors with static. Then replace the short section of tube from the toner cylinder to the toner pump unit. (B2343282).
    Perform toner bank setup (SP2207-002).
    Failing that, replace the toner pump unit (D0593260) and perform toner bank setup execution again.
