Frequently Asked Questions
Q: Why choose Zorsika over OEM?
A: Zorsika lenses are manufactured to OEM optical blueprints, with lens elements, coatings, and throw ratios matched one by one. Every unit undergoes resolution testing before shipment. Compared to OEM: shorter lead times and better value. Compared to other replacement lenses: optical quality backed by test data.
Q: Can the lens replace the OEM one?
A: The lens is the core of the projector's optical path, directly determining sharpness and color accuracy. Zorsika lenses (models listed in the specification table above) are matched item by item to OEM optical parameters (focal length, throw ratio, lens elements), with consistent coating process—delivering sharp images with no edge blurring. Generic replacement lenses often use ordinary glass with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is the recommended choice.
Q: My projector isn't on the 24-model list. Can I still use WK051?
A: The list represents verified models only, not an exhaustive inventory. Same-brand, same-generation engineering projectors often share lens interfaces. Send photos of your projector nameplate and original lens to Zorsika technical support for confirmation.
Q: Is there an installation guide for WK051?
A: Yes. Lens removal and installation steps are essentially consistent across Epson projectors. Contact Zorsika sales for illustrated or video guides specific to your model.
Q: What's the lens warranty period?
A: All Zorsika projector lenses come with a 12-month warranty. Normal use and non-human damage (such as impact, liquid intrusion, or unauthorized disassembly) can be handled directly through after-sales service. Warranty period is calculated from the shipment document date.
Lens Daily Maintenance Tips
- Power off before lens replacement: Always shut down and wait for the cooling fan to stop before removing or installing the lens. Avoid hot-swapping to prevent interface damage.
- Don't touch the lens elements: Fingerprints and oils directly affect image quality. Hold the lens barrel, not the elements. Use an air blower for dust—never wipe with cloth.
- Lock after focusing: After ensuring correct installation, focus first, then tighten the mounting screws. Loose screws over time can cause image drift.
- Keep interfaces clean: Dust on mounts and contacts causes poor connection. Clean them when replacing the lens for reliability.
