TD cartridge replacement required indicator
The TD cartridge replacement required indicator will light up when
toner is needed. If copying is continued while the indicator is lit,
copies will gradually become lighter until the copier stops and the
indicator begins blinking. Replace the old TD cartridge by following
the procedure given below.
After the copier stops, it may be possible to make a few more cop-
ies by taking the TD cartridge out of the copier, shaking it horizon-
tally, then reinstalling it. If copying is not possible after this
operation, replace the TD cartridge. During long copy run of a dark
original, the START key indicator may blink, the indicator light up,
and the copier stop, even though toner is left. The copier will feed
toner for up to 2 minutes and then the START key indicator will
light up. Press the START key to restart copying.
For best copying results, be sure to use only SHARP Genuine
Supplies which are designed, engineered and tested to maximize
the life and performance of SHARP copiers. Look for the Genuine
Supplies label on the toner package.
In case of low coverage, the developer life lamp lights up at 14,500
sheets, and flashes at 15,000 sheets and the machine stops.
Drum replacement required indicator The useful life of the drum
cartridge is approximately 30,000 copies. When the internal
counter reaches approximately 29,000 copies, the drum replace-
ment required indicator will light up indicating that replacement of
the drum cartridge will be needed soon. When the indicator begins
to blink, replace the drum cartridge by following the procedure
given below.
