Ideal storage conditions for toner cartridges:

1. temperature:
• Ideal: Between 10°C and 30°C
• Avoid extreme temperatures: excessive heat can damage the toner powder; extreme cold can cause moisture to condense.

2. relative humidity:
• Ideal: Between 20% and 60%, in a dry place.
• Humidity can cause the toner powder to clump together and affect print quality.

3. exposure to light:
• Avoid direct sunlight or strong fluorescent light.
• Light can damage sensitive parts such as the light-sensitive drum/imaging unit in some cartridges.

4. storage position:
• Store horizontally, preferably in the same position in which the cartridge will later be inserted into the printer.
• This prevents uneven distribution of the toner powder inside the cartridge.

5. original packaging:
• Leave the toner cartridge in its original packaging until you are ready to use it.
• This protects it from dust, light and moisture.

6. avoid shocks and vibrations:
• Store the cartridge in a stable, safe place without risk of falling or impact.

At Inkolor , we are committed to sustainable initiatives with a focus on efficiency, responsibility and environmental compatibility. We are pleased to present the most important measures that are an integral part of our corporate philosophy:

🌳 Reforestation and CO₂ compensation
In partnership with Tree-Nation, Inkolor plants a tree for every order placed. Tree-Nation is a globally recognized platform that supports reforestation projects and actively fights climate change. It is active in various countries and contributes not only to CO₂ sequestration, but also to restoring ecosystems, protecting biodiversity and supporting local communities.

🚚 Climate-compensated transport
The CO₂ emissions generated during the transport of our products - from the distribution center in Alpnach to you - are calculated and offset by environmental initiatives in cooperation with Swiss Post.

⚡ Renewable energy
Our distribution center in Alpnach is powered exclusively by electricity from renewable energy sources.

♻️ Collection and recycling of empty toners and other consumables
An empty printer cartridge takes around 450 years for nature to completely break down. In addition, a large amount of energy and resources are required to produce each new cartridge. It is important to us that as many consumables as possible are recycled. For this reason, we provide collection containers at public recycling centers. You can also send us any empty consumables of any brand for recycling to the following address:

Inkolor.ch GmbH

Hofmätteliweg 1

🛡️ ISO 14001 certification
The production of Inkolor is certified in accordance with the international ISO 14001 standard. This certification ensures that all relevant environmental aspects are systematically recorded, monitored and continuously improved.
By implementing this standard, we are committed to the responsible use of resources, the reduction of emissions and waste and compliance with all environmentally relevant legal requirements. In this way, we make an active contribution to environmental protection - right from the production phase.
Our products also meet the requirements of the European RoHS Directive, which restricts the use of hazardous substances in electrical and electronic equipment, and the REACH Regulation, which ensures the responsible use of chemical substances and thus actively contributes to the protection of people and the environment.
