Xerox WorkCentre 6400X: Legal-size scanning and included analog fax review

A color MFP with a genuinely Legal-size scanner

The Xerox WorkCentre 6400X is an earlier color laser multifunction printer with an unusually useful combination for document work: a Legal-size glass, automatic two-sided feeder scanning, confidential print release and included analog fax. Ethernet is the appropriate computer arrangement when scan retrieval matters. USB is explicitly print-only.

X adds fax capability to the S configuration. It does not include the XF model's two extra paper drawers, finisher or stand. That distinction affects both capacity and the space needed for the machine.

Count ordinary Letter and Legal paper separately

The standard X package has a 100-sheet multipurpose Tray 1 and a 500-sheet Tray 2, with capacities based on 20 lb, 75 gsm stock. Both accept ordinary Letter and A4, producing the familiar 600-sheet total.

Legal is different: the standard main drawer accepts only Letter and A4. Legal documents therefore use the 100-sheet bypass unless suitable optional drawers have actually been installed. A requirement for 600 included Legal sheets should not be satisfied by the general capacity headline.

Automatic two-sided printing is included. The guide documents the main-drawer duplex orientation for its Letter/A4 routine, with a general duplex weight range of 60–150 gsm. Match the paper type, source and binding direction in a compatible driver. The bypass's broader specialty-media range does not make every stock suitable for duplex.

Retrieve scans through the network mailbox

The 50-sheet feeder accepts originals from 148 by 210 to 216 by 356 mm at 50–105 gsm. Both the feeder and actual glass support Legal documents; this is more useful than a specification that offers Legal only through the feeder. Color scanning is also established.

The source confirms automatic two-sided feeder scanning, while its physical reversing or single-pass method remains unestablished. Select the appropriate sidedness and color settings for the originals. Glass scanning of a two-sided original remains a manual turn-and-rescan task.

A practical Ethernet routine stores a scan in the printer's public or configured private mailbox, then downloads it through CentreWare Internet Services. Enable the service and establish access permissions first. The default public scan is a one-sided color PDF; choose different settings before starting when required. A private folder provides the configured password policy, while desktop scan utilities additionally need their drivers.

Keep fax and confidential printing conditions clear

The X hardware includes embedded fax, which needs an appropriate analog telephone line and configured fax settings. At the panel, choose the fax service, enter the destination, set the document options and start the job. Ethernet is not a substitute for that telephone connection.

Server Fax and Internet Fax are separate arrangements requiring their server, repository or email configuration. They should not be treated as automatically active just because the model lists them.

For confidential computer output, choose Secure Print in a compatible driver and supply a 4–10 digit passcode. Use Job Status at the panel to select and release the job with the matching code. The machine includes its 80 GB hard drive; saved jobs and sample sets are distinct features from the secure-release routine.

Envelopes require a deliberate changeover

Only Tray 1 supports the documented envelope routine, with at most ten suitable envelopes. The guide calls for changing both grey fuser dials from Plain Paper to Envelope before loading, with care around the potentially hot fuser area.

Load envelopes short edge first with flaps up, placing a long-edge flap toward the right, then select the actual envelope format and type. Restore both dials to Plain Paper afterwards. Envelopes do not use automatic duplex, and their small allowance does not inherit the ordinary-sheet capacity.

Judge speed, supplies and space on their proper bases

The US specification declares up to 37 monochrome or 32 color pages per minute on Letter. A4 and Legal have separate lower figures, and scanner images per minute are different again. Recommended ordinary volume is up to 15,000 pages monthly; the 120,000 duty figure is expressly a nonsustained one-month maximum.

The original package includes declared 8,000-capacity CMY toner and 12,000-capacity black. Toner ISO yields, approximate imaging-unit life and fuser life use different measurement conditions. Match the exact supply and electrical part, particularly the US 110 V fuser.

The X body is declared at 20.8 by 23.1 by 24.7 inches and 130 pounds. Service space is substantially larger, including 10.5 inches behind the machine. Check both support strength and access. S is the related choice when fax is unnecessary; XF supplies more drawers and finishing in a much larger package.
