CHAPTER 1 D. Storing, Handling the EP-W Cartridge Whether the cartridge is still sealed in its box or installed in the printer, the effect of the natural 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 x 9/10) 0 to 35˚C Severe (total storage time x 1/10) High Low Temperature change (within 3 minutes or so) 35 to 40˚C -20 to 0˚C 40˚C →15˚C -20˚C →25˚C Normal (total storage time x 9/10) 35 to 85% RH Severe (total storage time x 1/10) High Low 85 to 95% RH 10 to 35% RH Air pressure Total storage time 345 to 1013 hPa (460 to 760 mmHg) 2 years 6 months 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.
