Temperature and humidity significantly affect the quality of toner powder. At Cartridge Web(CW), we incorporate environmental testing into our development phase. In this article, We will explore how temperature and humidity affect printing performance and provide tips for optimal toner cartridge storage conditions.
Effects of High Temperatures and Humidity 30°C (86°F) / 80%
Toner Caking
Extended exposure to high temperatures and humidity can cause toner powder to absorb excess moisture, leading to toner caking, which may damage the PCR and OPC surfaces. Continuous printing under these conditions can result in permanent damage to the printer consumables.
Premature Melting of Toner Powder
Toner powder is designed to melt and adhere to paper at specific temperatures through the fuser. However, when exposed to elevated temperatures, it may prematurely melt and clump on the fuser, resulting in paper jams during printing. Additionally, it will deliver poor printouts as shown below.
Effects of Low Temperature and Humidity 10°C (50°F) / 20%
Decreased Flowability
In low-temperature conditions, the flowability of toner can decrease, resulting in uneven printing.
Electrical Anomaly in Toner
Toner typically carries a negative charge, which allows it to adhere to the positively charged photoconductive drum. The static effect can be weakened in low temperatures and dry environments, resulting in electrical anomalies in the toner. This can cause the toner to attach improperly to the paper, negatively affecting transfer performance and print uniformity.
Cartridge Web Environmental Testing
Cartridge Web products are sold worldwide, so it is crucial to ensure consistent performance across various temperature and humidity environments. We undergo the environmental test through a climate chamber to simulate product performances under different temperatures and humidity. We conduct printing tests based on 5% coverage in compliance with ISO/IEC 19752, 19798, and 24712 test standards, as well as higher coverage tests that alternate between printing ISO 5% and ISO 15% manuscripts. By adhering to strict quality standards and processes, we ensure our clients a consistent supply of premium toner cartridges.
Storage Tips
- Toner cartridges should be stored in a room temperature (10°C–30°C / 50°F–86°F) and kept away from sunlight and excessive humidity
- Keep toner cartridges in their original packaging to protect them from dust and debris
- Shake toner cartridges thoroughly before installation to prevent clumping that may occur during transport or storage
Always purchase toner cartridges from a trusted source. Following these storage tips, you can maximize their lifespan and avoid wasting money on improperly stored cartridges.
