Q: Can I recycle the old Maintenance Kit when I replace it with a new one?

A: Xerox provides a Waste-to-Energy program -- a free service which safely and efficiently recovers valuable energy from used Xerox color printer supplies. Check the Eligible Items information to determine which consumable supplies are covered for your specific printer model.

Q: How do I use my printer as a color copier? Which scanners can I use?

A: By attaching a supported scanner to your Phaser^® 840 color printer, you can use the printer as a color copier. The following scanners are supported by the Phaser 840 color printer:

Manufacturer	Model	ADF* Support
Hewlett-Packard	HP ScanJet 6100C	Yes
Hewlett-Packard	HP ScanJet 6200C	Yes
Microtek	ScanMaker 4	Yes
Microtek	ScanMaker 9600XL	N/A

* ADF = automatic document feeder

Contact your local reseller for availability.

Please note:

• In general, only the models listed above will work. If a different scanner model made by either Hewlett-Packard or Microtek supports the identical command set, byte order, and color characteristics of one of the listed scanners, it may work. Scanners from other manufacturers will not work.

• To attach the scanner to your printer, you need a high-density SCSI-2 to 50-pin SCSI-1 interconnect cable (Xerox part number 013-0297-00). See Connecting Peripheral Devices.

• For instructions on using your printer as a color copier, see Using Your Printer with a Scanner.

• The Phaser 840 printer does not support the Xerox Phaser Copystation. Use the Phaser Copystation only with the following Xerox products: Phaser 540, 550, 560, 340, 350, 380, and 600 color printers.

A: The Phaser 840 Color Printer offers the following advantages over the Phaser 360 Color Printer:

• Faster PostScript processing with a 133 MHz RISC controller

• High Resolution Mode 600 x 1200 dpi printing

• 10 ppm (pages per minute) Fast Color mode

• Higher memory capacity (128 M bytes maximum)

• 10BaseT Ethernet (standard)

• Auto duplex option

• New built-in Copier feature

• Expanded front panel and user interface

• One year on-site warranty

Q: Does the Phaser 840 printer support DHCP?

A: Yes, the Phaser 840 printer does support DHCP. This allows network plug and play for Windows NT systems. For additional information on the use of DHCP, refer to the Microsoft Windows NT manuals.

Q: Does the Phaser 840 printer support 100BaseT networks?

A:Yes, the optional PhaserShare card has support for 100BaseT Ethernet environments. When this card installed, the built-in 10BaseT connection is disabled.

Q: I just bought my Phaser^® 840 Color Printer a couple of days ago and have only printed 50 pages or so. Now the printer's front panel says it's Out Of Ink. How could I have used up so much ink this quickly?

A: Most likely the printer has been turned off and on a couple of times and has already consumed the ink sticks that were loaded in the printer. The printer is shipped with one ColorStix^® ink stick of each color. This is enough ink to power up and print many pages.

At power-up, the printer cleans (or purges) each of its ink jets to ensure optimum image quality. This action takes around 15 minutes and uses some of each color-ink stick. Leaving the printer on, even during weekends, actually reduces ink consumption. The printer also has a built-in standby mode to reduce power consumption during periods of inactivity. If the printer hasn't been used in four hours, it drops into the standby mode. When a print job does arrive, the printer wakes up and handles the print request without unnecessarily purging ink.

Q: How do I set up print queues on my UNIX^® host?

A: The printer's internal LPR queue uses the BSD protocol; you must use one of the following names for the remote printer queue:

• PS for PostScript^®.
• HPGL for HP-GL^® (Hewlett-Packard Graphics Language).
• PCL for PCL^® (Printer Control Language).
• AUTO for Automatic language selection (the printer automatically senses the language of the print job and processes it accordingly).

If you want to print using Xerox^® PhaserPrint^TM 2.0 software, you must use PhaserPrint to configure your host. Refer to the PhaserPrint 2.0 user manual or the instructions provided with the PhaserPrint CD-ROM for configuration information.

If you are not using PhaserPrint, follow these instructions:

1. For SPARC^® and SGI^® platforms, modify the etc/hosts file to identify the printer to the workstation and modify the /etc/printcap file to describe the printer to the workstation. For more information, refer to Spooling configuration for SPARCstation platforms (24K PDF ) or Spooling configuration for SGI platforms (24K PDF ).
2. For Hewlett-Packard platforms, use the Hewlett-Packard System Administrator Manager (SAM). For more information, refer to Spooling configuration for HP platforms (24K PDF ).
3. For IBM RS/6000^TM platforms, use the IBM System Management program smit. For more information, refer to Spooling configuration for IBM RS/6000 platforms (24K PDF ).
4. For BSD hosts not listed here, refer to Sample spooler configuration for a typical BSD system (18K PDF ).
5. For System V hosts, configure the queue as a remote BSD print queue (support for TCP/IP lpr is required).

Q: Why don't the printed colors match the screen colors?

A: Monitors use an additive RGB color model to generate colors, and printers use a subtractive CMYK model to generate colors. Because monitors and printers use different color-generation models, color matching between the two is difficult.

In many cases, RGB-monitor colors are outside the range of colors possible on CMYK printers. This causes, for example, blues to be brighter on the screen than on the printed page.

TekColor^TM has two monitor simulations: Simulate Display and Vivid Color/Blue. These color corrections use two different algorithms to solve this color-mapping problem. Print the RGB Sampler file from the printer's front panel. This file is a chart that gives a good representation of the colors possible on the printer. This chart gives RGB-percentage values with each color printed, which you can use with almost any software application to remove the guesswork between matching RGB-monitor colors and the CMYK-printer colors.

Q: How do I enter the TCP/IP address in the Phaser^® 840 Color Printer?

A: You can set the IP Address, NetworkMask, and the Gateway Address from the Phaser 840 printer's front panel.

The printer computes the correct Broadcast Address based on the IP Address/NetworkMask sets given to it. It is the responsibility of your Administrator to assign an IP Address and a Network Mask for this printer.

1. When the front panel displays READY TO PRINT, press the down arrow button until Menu is highlighted. Press Select.
2. Press the down arrow button until Printer Configuration is highlighted. Press Select.
3. Press the down arrow button until Network Settings is highlighted. Press Select.
4. Press the down arrow button until TCP/IP is highlighted. Press Select.
5. Set the IP address:
1. Press the down arrow button until IP Address is highlighted. Press Select.
2. Press the left or right arrow buttons to highlight the 3-digit part of the address that you want to set. Press the up or down arrow keys to change the numbers.
3. When the address is set, press Select.
6. Set the network mask:
1. Press the down arrow button until NW Mask is highlighted. Press Select.
2. Press the left or right arrow buttons to highlight the 3-digit part of the address that you want to set. Press the up or down arrow keys to change the numbers.
3. When the address is set, press Select.
7. Set the default router/gateway address:
1. Press the down arrow button until Default Router/Gateway Address is highlighted. Press Select.
2. Press the left or right arrow buttons to highlight the 3-digit part of the address that you want to set. Press the up or down arrow keys to change the numbers.
3. When the address is set, press Select.
8. To return the printer to normal operation, press the down arrow button until Exit is highlighted. Press Select.

Q: How do I install my printer on a Windows^® NT server?

A: Use the following links to install the Windows NT 3.51 PostScript^® driver or the Windows NT 4.0 PostScript^® driver.

Q: What is the best way to clear and prevent paper jams?

A: Follow these instructions for removing a paper jam. Often you can prevent paper jams by following the recommended media weight guidelines. If the jam persists, try cleaning the printer.

Q: The printer is displaying a message telling me that the Maintenance Kit is low/empty. How can I clear this message?

A: The Maintenance Kit that ships with a new printer has a life of 10,000 prints. Replacement Maintenance Kits have a life of 30,000 prints. A front panel message tells you when the kit is low, allowing you to make a minimal number of prints before the tray is depleted. The front panel also indicates when the kit is empty. You must install a new Maintenance Kit to continue printing.

To order a Maintenance Kit, use the Xerox order number, 016-1727-00. Avoid printing delays by keeping an extra stock of Maintenance Kit available.

Q: Does the Phaser 840 Color Printer support duplex printing?

A: Yes, the Phaser 840 Color Printer supports a new option called Auto Duplex. This feature lets you print two-sided documents without the need to manually reorient paper in the media tray or manual feeder.

Q: Will my Phaser 840 Color Printer work with a scanner?

A: Yes. In fact the Phaser 840 Color Printer works with a variety of SCSI-compatible, third party scanners.

Q: Why does my document feed through the printer as if it is printing on two sides, yet I only want a one-sided print?

A: You have the duplex printing option turned on in the printer driver. When this option is on, even single-page documents print as if they are two-sided documents. To turn this option off, set the duplex (2-sided) printing option to "None" in the printer driver.
