Page 19 3 Using the printer This section provides information on media usage for the printer, changing print settings, and performing basic printing tasks. Page 20 Selecting print media The printer is designed to work well with most types of office paper. It is best to test a variety of print media types before buying large quantities. Use HP media for optimum print quality. See HP supplies and accessories. For more information about HP media, see www.hp.com. Tips for selecting and using print media For the best results, observe the following guidelines. ? Always use media that conforms to the printer specifications. Page 21 Transparencies. Insert transparencies with the rough side down and the adhesive strip pointing towards the back of the printer. ? Use the Best mode to print transparencies. This mode provides longer drying time and ensures that the ink dries completely before the next page is delivered to the output tray. Allowing wet media to stack up might cause smearing. Custom-size media ? Use only custom-size media supported by the printer. This setting might temporarily use a large amount of hard disk space (400 MB or more) and will result in slower printing. Following are general guidelines for loading media into the tray. If you are printing on thick paper (such as cardstock), you can use the rear manual feed slot. See Printing with the front or rear manual feed slot. ? If you are printing cards or envelopes, see Printing on special and custom-size media. Page 30 5.http://syonutisre.eklablog.com/bmw-750i-2008-manual-a203168596

Press the button on top of the paper guide and slide the guide to the right until it stops at the edge of the media. 6. Press the input tray lock and retract the tray until it stops at the edge of the media. NOTE When 215.9 x 279.4 mm (8.5 x 11 inch) paper is loaded in the input tray, the tray extension will close to the edge of the paper and leave a slight gap between the extension and the tray. The tray extends further to accommodate larger-sized media. 7. Lower the output tray. 8. Page 31 Loading small media To load small media in the input tray NOTE You can also use the front manual feed slot. If you are printing on thick paper (such as cardstock), you can use the rear manual feed slot. See Printing with the front or rear manual feed slot. 1. Raise the output tray and remove any media from the input tray. 2. Insert a stack of media that does not exceed the height of the paper guide, print-side down along the right side of the input tray until it stops. 3. Page 32 5. Press the input tray lock and slide the tray in until the small media guide stops at the edge of the media. As you slide the tray, the small media guide extends until it touches the edge of the media. 6. Lower the output tray. 7. When printing, select the appropriate media type and size from the printer driver. See Changing print settings. Page 33 Changing print settings You can change print settings (such as media size or type) from an application or the printer driver. Changes made from an application take precedence over changes made from the printer driver. However, after the application is closed, the settings return to the defaults configured in the printer driver. NOTE To set print settings for all print jobs, make the changes in the printer driver. This will clear the job that the printer is currently processing. Select the print job, and then press the Delete key on the keyboard.

Page 35 Printing with the front or rear manual feed slot If you are printing one or just a few photos, envelopes, or sheets of paper, you can use the front manual feed slot and leave your regular media in the input tray.

Page 37 2. Slide the paper guide to the required media width. 3. Insert a sheet of media print-side up into the left side of the slot until the printer grips the media. 4. Press (Resume button) to print. 5. If you are printing more than one page, press sheet. Page 38 Printing on both sides (duplexing) You can print on both sides of a sheet of media, either automatically by using the duplex unit or manually by turning the media over and feeding it into the printer again. Guidelines for duplexing. Always use media that conforms to the printer specifications. See Understanding specifications for supported media. ? Specify duplex options in your application or in the printer driver. Page 39 7. Select or clear the Flip Pages Up check box depending on which way you want the binding.

If the printer is connected to a network, the correct IP address is used. Resolving printing problems Printer shuts down unexpectedly Check power and power connections. Make sure the printer is connected firmly to a functioning alternating current (AC) power outlet.

See Printer specifications for voltage requirements. All printer lights are blinking A non-recoverable error has occurred. Reset the printer. Page 85 Check printer setup for network environment Ensure the correct printer software and printer software port are being used. For more information about network connections, see Configuring the printer (Windows), Configuring the printer (Mac OS), or the documentation provided by your network vendors. Check any personal firewall software installed on the computer The personal software firewall is a security program that protects a computer from intrusion. Page 86 Check media settings Make sure the page settings in the printer software matches the width and length of media loaded in the tray. See Changing print settings. Check the parallel port on your computer If you are using a parallel cable, make sure the printer is connected directly to the parallel port. Avoid sharing the port with other devices, such as a Zip drive or other printers. Page 87 Poor print quality and unexpected printouts Check the printheads and ink cartridges Replace any clogged or worn printheads or low ink cartridges (see Maintaining the printheads), and try to print again. Check the paper quality The paper might be too moist or too rough. Make sure the media used meets HP specifications (see Selecting print media), and try to print again. Check the type of media loaded in the printer. Make sure the tray supports the type of media you have loaded. Page 88 Check print settings. When you print documents that use a large quantity of ink, allow more time to dry before handling the printouts. This is especially true for transparencies. In the printer software, select the Best print quality. Also increase the ink drying time and reduce the ink saturation using an ink slider in conjunction with drying time under Advanced Printing Features (Windows) or Ink Features (Mac OS) in the printer software.

Page 89 Clean the print zone of the printer After extensive printing, ink might be deposited on the print zone of the printer, causing ink to smear on the non-printed side of the media or the edge of a stack of printed media. To remove the deposited ink, use a lint free cloth to clean the print zone, including the plastic ridges. Page 90 Ink is not filling the text or graphics completely Check the ink cartridges Ink cartridges might have run out of ink. Replace any empty cartridge. Or try removing and reinstalling the cartridges, make sure they snap firmly into place. See Replacing the ink cartridges. Check the media type Some media types are not suitable for use with the printer. See Selecting print media. Output is faded or dull colored Check the print mode The Fast Normal printer mode allows you to print at a faster rate. Page 91 Check ink cartridges Make sure ink cartridges have not been tampered with. Refilling processes and the use of incompatible inks can disrupt the intricate printing system and result in reduced print quality and damage to the printer. HP does not guarantee or support refilled ink cartridges. For ordering information, see HP supplies and accessories. Colors do not line up properly Check printheads The printheads are not automatically aligned when a printhead is replaced. Page 92 Pages are skewing. Make sure the paper guides in the tray are adjusted snugly against the media, but do not crinkle or bend it. ? Avoid loading media of different types or sizes in the tray. ? Make sure media in the tray is not curled. Uncurl paper by bending it in the opposite direction of the curl. ? Run a media skew test in the Toolbox. See Testing media skew. Page 93 Troubleshooting installation issues Problems printing alignment page When new printheads are installed, the printer automatically prints two alignment pages to align the printheads. This process takes about eight minutes.
