3) Details of pixel counter
- Toner cartridge reference and service technician reference
The pixel counter function in this equipment has 2 references, toner cartridge reference and ser-
vice 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 empty has exceeded the threshold.The threshold to
be used is selectable in the setting mode (08-1506) between the pixel count and output pages (0:
Output pages 1: Pixel counter). The threshold of pixel count is set in the setting mode (08-1508)
and that of output pages is set in the setting mode (08-1507).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(08-1503).
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.Clearing of the
counter of the service technician reference is performed in the setting mode(08-1502).
- Print count (number of output pages)
The number of output pages shown at the pixel counter is counted after converting all paper
sizes to the standard paper size (A4/LT). Printing on other than the standard size is converted by
paper area ratio. The standard paper size is set in the setting mode (08-1500).The examples of
conversion are as follows:
Ex.)
1. "1" is added to the print count when printing on A4/LT size.
2. "2" is added to the print count when printing on A3/LD size. (area ratio to A4/LT: 200%)
3. "1.49" is added to the print count when printing on B4 size. (area ratio to A4: 149%)
4. "1.27" is added to the print count when printing on LG size. (area ratio to LT: 127%)
- Pixel count (%)
Pixel count (%) shows the ratio of laser emitting pixels to all pixels on standard paper.
The examples of pixel count are as follows:
Note: Note:
In the following examples, 'solid copy' is considered to be 100%. But since the image has 4
margins, it never becomes 100% actually.
Ex.)
1. Printing 5 pages on A4/LT size with solid copy (Laser emits to all pixels.)
→ Pixel count: 100%, Print count: 5
2. Printing 5 pages on A4/LT size with blank copy (Laser never emits.)
→ Pixel count: 0%, Print count: 5
3. Printing 2 pages on A4/LT size with solid copy (Laser emits to all pixels.)
Printing 2 pages on A4/LT size with blank copy (Laser never emits.)
→ Pixel count: 50%, Print count: 4
