 The management items at PM support mode can also b e operated at setting mode (08).
The following items are displayed or set by using s ub-codes at PM management setting in the table 
below.

0: Present number of output pages - Means the present number of output pages.
1: Recommended number of output pages for replaceme nt
- Means the recommended number of output pages for  replacement.
2: Number of output pages at the last replacement
- Means the number of output pages at the last repl acement.
3: Present driving counts - Means the present drive counts (1 count = 2 secon ds).
4: Recommended driving counts to be replaced - Means the recommended drive counts for replacemen t (1 count = 2 seconds).
5: Driving counts at the last replacement - Means the drive counts at the last replacement.
6: Present output pages for control
- Means the present number of output pages for cont rolling.
7: Present driving counts for control - Means the present drive counts for controlling (1  count = 2 seconds).
8: Number of times replaced
- Counts up when clearing the counter of each unit i n the PM Support Mode Screen.
Notes: 
 Sub-code 3 is equivalent to sub-code 7. 
 When the value of sub-code 3 is changed, the value  of sub-code 7 is also updated and vice 
versa.
 When “0” is set at one of sub-codes 0, 3, 6 and 7,  the rest of them are automatically updated 
to “0”.

2.2.9 Pixel counter
1) Outline Pixel counter is a function that counts the number o f dots emitted by the laser and converts it into the 
print ratio (%) per standard paper size. This “Prin t ratio (%) per standard paper size” is called Pixel 
count (%). 
This function enables you to know how each user use s the equipment and to grasp the tendency of 
toner consumption (number of output pages per cartr idge).

2) Factors affecting toner consumptionStandard number of output pages per cartridge shows  the average number of output pages under 
the condition that the data of print ratio 6% is pr inted on the standard paper size (A4/LT) at a norma l 
temperature and humidity. 
However, users do not always print under the above  condition. As for the type of original, copy/print 
mode and environment, each user has different tende ncy, and as a result, the number of output 
pages per cartridge becomes different depending on  the user.
The major factors affecting toner consumption are a s follows:
- Original/Data coverage
- Original/Data density 
- Original/Print mode 
- Density setting
Also there are other factors in addition to the abo ve, such as environment, individual difference of 
equipment, difference in lot quality of materials,  toner density and drum surface potential.
The general relations between the 4 factors mention ed in the previous page and toner consumption 
per output page in the Copier Function are as follo ws:

3) Details of pixel counter - Toner cartridge reference and service technician re ference
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 w hen the total number of pixel count or output 
pages after the detection of toner empty has exceede d the threshold.
The threshold to be used is selectable in the setti ng mode (08-1506) between the pixel count and 
output pages (0: Output pages 1: Pixel counter). Th e threshold of pixel count is set in the setting 
mode (08-1508) and that of output pages is set in t he setting mode (08-1507). When the new 
toner cartridge is judged as installed, the data re lated with the previous cartridge is cleared and 
replaced with the data after the installation of ne w cartridge. Clearing of the counter of the toner 
cartridge reference is performed in the setting mod e (08-1503).
Service technician reference
This is a system that accumulates data between clea ring the counter of the service technician 
reference by service technician and subsequently cl earing the same counter.
Clearing of the counter of the service technician r eference is performed in the setting mode (08-
1502).
- Print count (number of output pages) The number of output pages shown at the pixel count er 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” is added to the print count when printing on A4 /LT size.
“2” is added to the print count when printing on A3 /LD size. (area ratio to A4/LT: 200%)
“1.49” is added to the print count when printing on  B4 size. (area ratio to A4: 149%)
“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 p ixels to all pixels on standard paper.
The examples of pixel count are as follows: 
Ex.) 
Printing 5 pages on A4/LT size with solid copy (Las er emits to all pixels.)
  Pixel count: 100%, Print count: 5
Printing 5 pages on A4/LT size with blank copy (Las er never emits.)
  Pixel count: 0%, Print count: 5
Printing 2 pages on A4/LT size with solid copy (Las er emits to all pixels.)
Printing 2 pages on A4/LT size with blank copy (Las er never emits.)
  Pixel count: 50%, Print count: 4
Printing 3 pages on A4/LT size with 6% of laser emi ssion
Printing 1 page on A4/LT size with 2% of laser emis sion
  Pixel count: 5%, Print count: 4
Printing 2 pages on A3/LD size with solid copy (Las er emits to all pixels.)
  Pixel count: 100%, Print count: 4
Printing 2 pages on A3/LD size with 6% of laser emi ssion
  Pixel count: 6%, Print count: 4
- Average pixel count (%) and latest pixel count (%) There are 2 types of the value calculated as the pi xel count, average pixel count (%) and latest 
pixel count (%). 
Average pixel count (%) 
The average value of all pixel count data after eac h reference data is cleared is calculated and 
displayed. 
Latest pixel count (%) 
The value is displayed for printing just before the  pixel counter is confirmed.
Note: Note: 
In the following examples, ‘solid copy’ is considere d to be 100%. But since the image has 4 
margins, it never becomes 100% actually.
