CHAPTER 1

D. Storing, Handling the EP-72 Cartridge

Whether the cartridge is still sealed in its box or installed in the printer, the effect of the natur- al environment will change it over time regardless of the number of prints. As the progression of this natural change depends on the storage or installation environment, take sufficient care in storing and handling the cartridges.

1. Before unsealing the box

When the cartridge is stored in a warehouse, workshop, etc., be sure to keep it within the ranges shown in Table 1-5-1. Note the following points:

1)Avoid locations in direct sunlight.

2)Do not leave in areas exposed to strong vibration.

3)Do not bump or drop.

Table 1-5-1 Storage temperature and humidity conditions

Temperature

Relative humidity

	Normal (total storage time ×		0 to 35°C
	9/10)
	Severe (total storage	High	35 to 40°C
	time × 1/10)	Low	–20 to 0°C
			40°C→15°C
Temperature change (within
3 minutes or so)			–20°C→25°C
	Normal (total storage time ×		35 to 85% RH
	9/10)
	Severe (total storage	High	85 to 95% RH
	time 1/10)	Low	10 to 35% RH
	Air pressure		345 to 1013 hPa
			(460 to 760 mmHg)

Note: Total storage time is the valid time span following the manufacture date displayed on the cartridge box.

2. After unsealing the box

As an organic photoconductor (OPC) is used in the photosensitive drum, it will deteriorate if exposed to strong light. As there is toner in the cartridge, be sure to explain to the customer the need to be careful in handling and storing unsealed cartridges.

a. Storage environment

1)Be sure to store in the aluminum bag.

2)Avoid locations exposed to direct sunlight, near windows, etc. Do not leave them in cars for any extended period of time as heat can damage the cartridges.

3)Avoid high, low, and changeable temperature/humidity locations.

4)Avoid sites with corrosive gases (pesticides) or salt in the air.

5)Store the cartridge within a range of 0 to 35°C.

6)Do not leave cartridges near CRT displays, disk drives or floppy disks.

7)Store the cartridges out of reach of children.
