About Jovisor
Jovisor is the export brand of GW Jinyun, a compatible toner manufacturer based in Shenzhen, China. We have been supplying cartridges to domestic distributors, print shops and corporate buyers since 2010, and now ship to importers and dealers in the Middle East, Southeast Asia, Latin America, Russia and Africa.
Who you are actually buying from
This matters more than usual in this industry, because brand names tend to be unrelated. To be explicit:
| Export brand | Jovisor — jovisor.com |
|---|---|
| Domestic brand | GW Jinyun (GW 金运), sold in China |
| Legal entity | Shenzhen Juewei Zhichuang Technology Co., Ltd. |
| Chinese name | 深圳觉微智创科技有限公司 |
| Location | Shenzhen, Guangdong, China |
| Business | Compatible toner cartridges, drum units and toner powder |
All three names refer to the same company. Ask for a business licence copy before you place a first order — any serious supplier will send one.
What we actually do well
Adaptation data, not guesswork
Our cartridge-to-printer mapping covers 158 export codes and 1384 printer models, built and corrected by hand over years. When a customer asks “will this fit my machine”, we answer with a record, not an opinion.
Honest yield numbers
Every code is quoted at 5% coverage on A4 using ISO/IEC 19752 methodology. We would rather lose an order than ship a yield claim the buyer has to apologise for later.
Chip version matched to firmware
Printer firmware updates break chip compatibility more often than cartridge quality does. We ask for the printer model and firmware before shipping, and match the chip accordingly.
Small MOQ, mixed codes
Five pieces per code, mixed across codes. That lets a dealer test a market before committing to a container.
How we work with importers
- You send the cartridge codes or the printer models you need.
- We confirm fitment, chip version and available stock, then quote FOB with MOQ and lead time.
- Samples ship first — usually 2–5 pieces — so you test before committing.
- Compliance documents for your market are prepared before the shipment leaves.
