CHAPTER 1
b . After taking out of the package (removing the seal)
The photosensitive drum is made of photoconducting material (OPC), and tends to deteriorate
when exposed to strong light. The toner is also kept inside the cartridge, requiring care after the
cartridge has been taken out its the package. Advise the user to take full care when handling/
storing the cartridge.
1 . Storing the cartridge after taking out of the package (removing the seal)
1 . Be sure to keep it in a protective bag.
2 . Avoid areas exposed to direct rays of the sun or near windows. Do not leave it in side a car for
a long time, as the rise in temperature can be extreme.
3 . Avoid areas subject to high/low temperature/humidity or areas subject to extreme changes in
temperature or humidity.
4 . Avoid areas subject to corrosive gases (e.g., insecticide) or areas subject to briny air.
5 . Make sure that the temperature is between 0ºC and 35ºC.
6 . Avoid CRT displays, disk drives, or floppy disks.
7 . Keep it out of reach of children.
2 . Effective period
The cartridge is verified to remain good for 2.5 years after the date of manufacture, indicated on its
body using an abbreviated notation. For the user, the period is indicated on the package and the
packing boxes (year, month; 2.5 years after the date of manufacture).
The use of a cartridge after the date indicated may not bring about expected print quality,
making it desirable to use it up before the date indicated.
c . Points to note when handling
1 . When fitting a new cartridge, or if some areas of the output image show white spots because of
an uneven level of the toner inside the cartridge, hold the cartridge as shown, and shake it
carefully to the left and right [1] about 5 to 6 times then up and down [2] about 5 to 6 times to
even out the toner.

2 . When transporting the Printer after taking out the cartridge from it, be sure to secure the
transfer charging roller in place for protection. Keep the cartridge in a protective bag to avoid
light. (See VI. ‘Relocating the Printer.’)
3 . Do not place the cartridge near a CRT display, disk drive, or floppy disk. The magnetism from
the cartridge can damage the data.
4 . The photosensitive drum is vulnerable to strong light. Avoid subjecting it to direct rays of the
sun or light 1500 lux or higher in strength. When exposed, it can produce images with white
spots or black bands. (If they occur, leave the machine alone for a while to correct the faults. If
the exposure is long, however, white spots or black bands may continue.)
