• Toner cartridge reference and service technician reference
The pixel counter function in this equipment has 2 references, toner cartridge reference and service
technician reference.
Toner cartridge reference
This is a system that accumulates data between the installation of a new toner cartridge and next
installation.
The installation of new toner cartridge is judged when the total number of pixel count or output
pages after the detection of toner cartridge empty has exceeded the threshold.
The threshold to be used is selectable in the setting mode (08-6506) between the pixel count and
output pages (0: Output pages 1: Pixel counter). The threshold of pixel count is set in the setting
mode (08-6508) and that of output pages is set in the setting mode (08-6507). When the new toner
cartridge is judged as installed, the data related with the previous cartridge is cleared and replaced
with the data after the installation of new cartridge. Clearing of the counter of the toner cartridge
reference is performed in the setting mode (08-6503).
Service technician reference
This is a system that accumulates data between clearing the counter of the service technician
reference by service technician and subsequently clearing the same counter.
