Chapter 2 Basic operations
When the toner level runs low, the Toner lamp will flash. Although plots
can still be produced under this condition, obtain a new toner cartridge as
soon as possible and replace the toner.
When there is no more toner availabe, the Toner lamp will go out, the
Error lamp will come on, and printing will no longer be possible. The
following message appears on the LCD.
If the Toner lamp starts flashing or the ERROR message appears, replace
the toner according to the procedures indicated below.

◆ When you open the toner door, you will find a “Toner
replacement” label affixed to the inside surface. Refer to this
when replacing toner.
◆ After the Toner lamp starts flashing, approximately 50 m of
plots can be produce at normal size and density.
◆If plots with a high printing rate—such as drawings
containing many solid print areas and inversed (black and
white inverted) drawings—are printed just before the toner
runs out, the toner may be used up and the device may be
damaged.
To avoid such a case, refill toner as soon as possible when
the toner lamp is flashing.
