Used to checkthe heater lamp drive circuit.
If the heaterlampflashesduringthe above cycletith the status “H2. or .H4” on display,the failureis in the LSI input
line, notthe outputlines.(Probablythermistoror LSI failure).
If the lamps stay ON or OFF continuously,there may be a failurein the triac, heater lamp, or the LSI outputlines.

07 The copy lamp is turnedon for 5 seconds.

Duringthe firstone second, a fullpowervoltage is added,then the voltage appropriateto the ex~sure settingwillbe
added.
IMPORTANT: ~is test command must be executed with the original cover open, in order to prevent continuing

exposure of the copy lamp lightover the photoconductordrum. Neither, continuingexecutionof this
