Frequently Asked Questions
Q: What if the lens doesn't match the screen size?
A: First confirm the lens interface and optical axis position of your projector model, then select a lens with the corresponding throw ratio based on the actual installation distance. If unsure, send the installation distance and screen dimensions to Zorsika technical support and we will help you choose.
Q: My model is not on the 2-model list above. Can I use 902M9?
A: The list shows verified models only, not all possible ones. Projectors of the same brand and generation often share lens interfaces. Send photos of your machine nameplate and original lens to Zorsika technical support for confirmation.
Q: Can this lens replace the OEM lens?
A: The lens is the core of the projector optical path, directly determining clarity and color. Zorsika lenses (models in the specifications table above) are matched item by item against OEM optical parameters (focal length, throw ratio, lens group), with consistent lens coating process, delivering sharp imaging without edge distortion. Ordinary replacement lenses often use regular glass lenses with insufficient coating layers, resulting in noticeable brightness loss and color shift. For engineering and exhibition applications, Zorsika is recommended.
Q: Why choose Zorsika over OEM?
A: Zorsika lenses are manufactured according to OEM optical drawings, with lens groups, coatings and throw ratios matched item by item. Each unit undergoes resolution testing before shipment. Compared to OEM, Zorsika offers shorter lead times and better overall value; compared to other replacement lenses, optical quality is guaranteed with data.
Q: What is the lens warranty period?
A: All Zorsika projector lenses come with 12 months warranty. For normal use and non-human damage (such as impact, water damage, unauthorized disassembly), contact after-sales service directly. Warranty period is based on the shipping invoice date.
Why Choose Zorsika Despite the Same Specifications?
Zorsika offers an OEM-spec replacement lens for 902M9, with key parameters matched against the original manufacturer item by item, supporting project bulk purchasing and supply.
Zorsika's same-spec replacement model is compatible with Ricoh PJ RU7700L and PJ RU8800L—2 models in total; enter 902M9 in Zorsika's online lookup system to view the complete compatible model list.
- Optical Matching: Focal length, throw ratio, and lens elements are matched to OEM specifications
- Resolution Testing: Each unit is tested before shipment, MTF data is available upon request
- Coating Process: Lens coating is on par with OEM grade, minimizing light loss
- Stable Supply: Supports bulk purchasing and project-based supply
Bottom line: The lens is the core of optical performance—don't gamble with image quality over a price difference. Zorsika projector lenses are manufactured according to OEM blueprints, delivering comprehensive advantages.
Note: Actual imaging performance depends on projector condition and installation environment. For bulk orders, it is recommended to request one unit for testing first.
What to Watch for When Replacing the Lens?
- Power off first: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens. Avoid working with power on to prevent interface damage.
- Don't touch the glass: Fingerprints and oils directly affect image quality. Hold the lens by the barrel and avoid touching the glass. Use an air blower for dust—do not wipe with cloth.
- Focus before locking: After positioning the lens, test focus first, then tighten the mounting screws. This prevents loosened screws from causing image drift over time.
- Keep the interface clean: Dust on the mount and contacts causes poor connection. Clean them during lens replacement for better reliability.
