Jerry at SOP is great.

I'm skeptical of vendors we’ve found online until they prove themselves. We have appreciated Jerry’s high-touch personal approach on toner. He has earned the trust we put in him and his product.

Frequently asked question

Do SOP-TECHNOLOGIES toners contain developers in them?

Each cartridge is filled with toner and the exact developer ratio in them according to the printer manufacturer's specifications. We only use genuine developers in our Japan toners.

Do the toner cartridges come with chips?

Yes, each toner cartridge has chips installed in them. For most Xerox cartridges, they have assigned toner chip versions based on regions, such as Asia, North America, South America, Europe, and Metered. So it is important to know your chip version when buying toner cartridges specially for Xerox brands.

Will it ruin my printer if I use SOP-TECHNOLOGIES toner products?

No! Our toners are Japan-made, and they are designed to work on your printer. Over the years, our factory decided to use genuine developers to produce high-quality toner products that meet, if not exceed, the printer manufacturer's requirements.

Do you provide technical support?

Yes. We provide technical support to our customers, and we have certified technicians in our network who have years of experience in the industry. SOP-TECHNOLOGIES partners and supplies parts and other copier consumables to hundreds of copier service companies nationwide and abroad.

What is Remanufactured products?

Remanufactured products are products that have ended their useful life. In order to restore their original functionality and be sold for commercial use as remanufactured products, trained engineers remanufacture the equipment that would be considered as waste and bring them into a functional state by replacing essential parts without altering their design and functionality. Our factory ensures that we only use parts that meet the highest standards to ensure their durability and functionality. Each remanufactured product is tested and inspected before being released to the market. By buying remanufactured products, not only are you saving money, but you are also saving the environment.

How do I know if the product is compatible with my printer?

We listed the product descriptions and its compatible printers on each listed product on our website. Also, you always contact us when assistance is needed. We have individuals dedicated to answering questions and providing needed support.

How can I purchase products?

1. You can create an account by providing basic information and securing it with a password so you can keep track of your purchases. 2. You give us a call so we can create an invoice for you and email it to you for payment of your choosing.

Do you keep a record of customers' financial information?

No! Though our payment portal is secured, we don't keep a record of your financial information. Because of that, you are required to enter your financial information every time you make a purchase. When paying over the phone is necessary, we make sure that we enter your financial information into our system for a one-time purchase transaction only.
