# Scanners not supported by SANE

## Manufacturer and model

Epson Stylus DX4450

## Bus type

USB

## Vendor ID

0x04b8

## Product ID

0x083f

## Chipset

## Comments

The DX4450 is one of the 'All in one' style products. The printer seems to work ok with the DX3850 driver.
0x083f's the product ID for the DX4400. There is an "alpha" version available for the DX4400 (and a bunch of other similar models) here.
Note, you have to install both iscan AND iscan-pluging-cx4400.

# 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.
