# Scanners not supported by SANE

## Manufacturer and model

Visioneer 4800 USB
Vantas 3000
Xerox One Touch 4800

## Bus type

USB

## Vendor ID

0x04a7

## Product ID

0x0224

## Chipset

Realtek RTS8801B

## Comments

The Vantas and Xerox scanners seem to be clones of the Visioneer scanner (or vice versa). However, there also seems to exist another variant of the Xerox scanner ("Xerox 4800 One Touch") which has product id 0x03a0.

Looks similar to OneTouch 5800 and 8920.
Identical output in comparison to 5300 and Microtek Scanport 3000.

# Want to add or correct information?

If anything is wrong or missing on this page please file a bug report or use the the form for adding an unsupported device.

If you own an unsupported scanner, please send as much information as possible. Especially the output of sane-find-scanner -v -v and/or cat /proc/scsi/scsi (for SCSI scanners) or cat /proc/bus/usb/devices (for USB scanners) can help. If you dare to open the scanner, have a look at the text that's printed on the chips. That may help to identify the chipset. If you know that the scanner is similar to another one (e.g. supported by the same Windows driver), please also mention this fact.

# Information for Manufacturers

Are you a manufacturer or vendor of scanners and one of your scanners is not supported by SANE yet? In this case please have a look at our information for manufacturers.
