                                             Service Bulletin
 SB Number:           SB 2DC-005                        Creation Date: 17/09/2003
 Subject:             Service calls C7980 / 7990 (supplement to Service Manual)
 Model:               KM-1500



                    What to do when service calls C7980 or C7990 appear?


C7980:         Waste toner reservoir overflow with less than 100K copies
C7990:         Waste toner reservoir overflow with 100K copies or more


Since the following procedure is not described in the current KM-1500 service manual, this Service Bulletin
                                       has been published instead.


Procedure
    If above service calls arise, please take the process unit out of the machine, shake it horizontally
    several times and put it back into the machine.
    If the C code is then not cleared after switching first the power source off and on, please replace the
    process unit.
    If the C code is still not cleared after replacing the process unit and turning power source off and on
    again, please replace the `Waste Toner Sensor' or the `Engine Board'.


Background

When the waste toner sensor detects a `near-full' level, `E31' will be displayed to advise the user that the
timing to replace the process unit is almost reached. If after display of E31, the machine is however still
used continuously (for approx. 1,000 copies), the C code C7980 / 7990 will be displayed and the machine
will eventually lock.
