ScanSnap ix500 Roller Replacement Silicone Tube Repair

Set of 4, use with tube cutter.

Not genuine parts.
These are silicone tubes for replacing the feed rollers and ejection rollers of the Scan Snap ix500.
Silicone tube: Inner diameter 6.5mm, Outer diameter 13mm, Length 24mm (front and back).

These are for replacing the degraded rubber rollers of the ScanSnap. There are two methods: complete disassembly or partial replacement by cutting a slit vertically. These tubes can be used as is for complete disassembly, or by making a slit for partial replacement.

Method for Complete Disassembly Replacement:
The process is too lengthy to describe here, so please search online. There is no difference in normal use, and although it takes time, the result will be aesthetically perfect.

Method for Partial Replacement:
1. Remove the feed rollers and ejection rollers by making a vertical slit with a cutter and pulling them off. If hydrolysis has progressed, you may need to remove stickiness with anhydrous ethanol and cotton swabs.
2. Make a vertical slit in the new tube and set it onto the feed roller and ejection roller shafts, using the rotation of the power button to help.
I haven't used it, but you may need to use adhesive. If it spins freely, please secure it completely with adhesive or similar.

This is just a surplus from personal purchase, so the quality differs from products sold by companies. If you are concerned about burrs, please purchase those instead.
If the quantity is insufficient, a refund will be processed.
