Chapter 6 Printing with color

Using color

This device offers great color as soon as you set it up. It provides a combination of automatic color features to generate excellent color results for the general user, plus sophisticated tools for the experienced color user. The device provides carefully designed and tested color tables to provide smooth, accurate color rendition of all printable colors.

Media selection

For the best color and image quality, it is important to select the appropriate media type from the software printer menu or from the printer driver. See Media specifications for more information.

HP ImageREt 2400

HP ImageREt 2400 is a technology that provides the best color print quality without having to change driver settings or make tradeoffs among print quality, performance, and memory. ImageREt 2400 uses laser printing to produce sharp images and crisp, clear text. HP ImageREt 2400 provides emulated 2400 dpi color laser-class quality through a multiplelevel printing process. This process precisely controls color by combining up to four colors within a single dot and by varying the amount of toner in a given area. As a result, ImageREt 2400, together with the 600 x 600 engine resolution, creates millions of smooth colors.

Managing color options

Setting color options to Automatic typically produces the best possible print quality for color documents. However, in some situations, you might want to print a color document in grayscale (black and shades of gray) or to change one of the device color options. Windows: Print in grayscale or change the color options by using settings on the Color tab in the printer driver. Mac OS 9.2.2: Print in grayscale or change the color options by using the Color Matching pop-up menu in the Print dialog box. Mac OS 10.2, 10.3: Print in grayscale or change the color options by selecting Color Options, and then clicking Show Advanced Options in the Print dialog box.

Use the table in this section to solve problems that might occur when receiving faxes. Note You must use the fax cord that came with the device in order to ensure that the device functions correctly.
Problem The device cannot receive faxes from an extension telephone.
Cause The extension-telephone setting might be disabled.
Solution See Making an extension telephone available to receive faxes for instructions about changing this setting. Verify that the fax cord is securely connected between the telephone jack and the device (or another device that is connected to the device). Press 1-2-3 in sequence (tonedial mode only), wait for three seconds, and then hang up. Verify that the device dialing mode is set to Tone. See Selecting tone-dialing or pulsedialing mode. Verify that the extension phone is set up for tone dialing as well.
The fax cord might not be securely connected.
The device dialing mode might be incorrectly set, or the extension phone might be incorrectly set.
Problem Incoming fax calls are not being answered by the device.
Cause The answer mode might be set to Manual.
Solution If the answer mode is set to Manual, the device does not answer calls. You have to start the fax-receiving process manually. See Setting the answer mode for more information. Check the rings-to-answer setting for your configuration. See Changing the rings-toanswer setting to determine which setting you need. Check the answer-ring pattern feature to verify that it is set properly. See Changing ring patterns for call answering. See the Getting Started Guide to check the installation. Verify that you are using the fax cord that came with the device. Re-record your answering machine message, leaving at least two seconds of silence at the beginning of the message. You should not have more than three devices attached to the line. Try removing the last device that was connected and determine whether the device works. If not, continue removing devices one at a time and retry after removing each one. Do one of the following: Increase the volume on the device, and then press START FAX on the control panel. If you hear a dial tone, the telephone line is working. Disconnect the device from the telephone jack, and then connect a telephone. Try to make a telephone call to verify that the telephone line is working.
