After the TRU waste toner amount detection sensor has detected the near-full status, and the
number of prints has reached the specified value (08-4597), the TRU waste toner box is judged
as being full. The count value of the number of prints is stored in the SRAM board until it reaches
the specified value. When the SRAM board is replaced, the data stored in the SRAM board are
reset. Check the TRU waste toner box and if the amount of the waste toner exceeds the position
of the line shown in the following figure, replace the TRU waste toner box.
