- Setting related with the pixel counter function
Standard paper size setting
The standard paper size (A4 or LT) to convert it into the pixel count is selected (08-6500).
Pixel counter display setting
Whether or not to display the pixel counter on the LCD screen is selected (08-6504).
Display reference setting
The reference when displaying the pixel counter on the LCD screen (toner cartridge reference or
service technician reference) is selected (08-6505).
Determination counter of toner empty
This is the counter to determine the replacement of new toner cartridge after the toner empty is
detected.
After the toner empty is detected by the auto-toner sensor, this counter checks if toner empty is
not detected one more time while the specified number of pixel count or output pages is counted.
Pixel counter clearing
There are 3 types for the pixel count clear as follows:
08-6501: All information related to the pixel count is cleared.
08-6502: All information related to the service technician reference pixel count is cleared.
08-6503: All information related to the toner cartridge reference pixel count is cleared.
4. Relation between pixel count and toner consumption
The user's printing out the image with large coverage or high density may cause the large value of
pixel count. And the setting that toner consumption becomes high in the original mode or density
setting may cause it as well.
In this case, the replacement cycle of toner cartridge is faster than the standard number of output
pages. Therefore, this trend needs to be grasped for the service.
The relation between pixel count and number of output pages per cartridge is as follows:
