About This Original Lens

Ricoh 512917 Long Zoom #A4 Lens

The 512917 Long Zoom #A4 is a long throw lens produced by Ricoh. Its optical structure, lens coatings, and body tolerances are matched to the original machine's standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., short-throw large-screen setups, ultra-short-throw wall-mounted installations), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 1.52-2.92:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (suitable for close-range, small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the on-site installation distance and screen size, then match it to this model.

Authenticity and Procurement Information

Zorsika supplies the Ricoh original lens 512917 Long Zoom #A4 through authentic channels, with original packaging and verifiable serial numbers, suitable for bulk procurement and project supply for engineering projections, conference rooms, classrooms, and other projects.

• Authenticity Guarantee: Sourced through official OEM channels with original packaging and serial numbers. Bulk projects can request channel credentials to eliminate refurbished units and sources of unknown origin.
• Compatibility Verification: Provide the machine model before ordering; Zorsika technical support will verify against the compatible model list above to avoid installation issues.
• Project Supply: The 512917 Long Zoom #A4 covers 2 models. For common projects, scheduling in advance can shorten delivery times.
• Alternative Solutions: For budget-sensitive projects, Zorsika can also provide alternative lenses with equivalent specifications, with key parameters matching the OEM, for selection as needed.

Note: Actual imaging performance is affected by the machine's condition and installation environment. For large bulk orders, it is recommended to first obtain one unit for testing.

Frequently Asked Questions

Q: How to choose between an original lens and an alternative lens?

A: Original lenses are produced by Ricoh, with optical parameters and body tolerances calibrated to the original machine, suitable for projects with strict requirements for OEM consistency. Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, imaging circle, and mount matching the original machine, offering advantages in budget and delivery time. Zorsika supplies both lines; choose based on project requirements.

Q: How can I confirm if this lens will work with my machine?

A: Compatibility is based on the machine's lens interface and panel/chip size. This article lists verified compatible models. Engineering machines of the same generation and brand often share interfaces. If unsure, take a photo of the machine's nameplate and send it to Zorsika technical support for confirmation.

Q: How to choose the throw ratio?

A: Throw ratio = projection distance ÷ image width. A smaller value produces a larger image (short/ultra-short throw suitable for close-range, small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the installation distance and screen size, then match it to the focal range of this model.

Q: How can I ensure the 512917 Long Zoom #A4 is authentic?

A: Zorsika supplies authentic products through OEM channels, with original packaging and verifiable serial numbers. Bulk projects can request channel credentials to ensure the units are not refurbished or second-hand parts.

Q: What should I pay attention to when replacing the lens?

A: Before disassembly/assembly, ensure the machine is powered off and wait for the cooling fan to stop. Hold the lens by the barrel, avoiding contact with the lens elements. Use a blower to gently remove dust. After installation, perform a focus test before tightening the mounting screws, and clean the mount and contacts.

Q: What is the warranty period for the lens?

A: Zorsika provides a 12-month warranty for all projector lenses. For normal use and non-human-caused damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
