Page 28 Printing Basics How to choose paper Most plain photocopy paper, postcards, index cards, transparencies, envelopes and labels work fine in your printer, particularly paper that is marked for use in inkjet printers. To get the best results, use one of the Hewlett-Packard papers, which were developed especially for HP inks and your printer.https://riverasphotovideo.com/wp-content/plugins/formcraft/file-upload/server/content/files/162708845193a8---bostitch-sb--150sx-manual.pdf You can use any size paper that fits easily within the paper adjusters of the printer. Because your printer uses ink to produce an image, paper that accepts ink well produces the best results. Be sure to test a variety of paper types before buying large quantities. HP papers are available at most computer supply stores. See “Supplies and accessories” on page 70 for paper ordering information. Page 30 Finding the HP print settings box After you lay out the page and choose the text, pictures, fonts, and colors from your software program, you need to select settings such as paper type, paper size, orientation, and print quality in the HP print settings box.

Page 33 2 Click OK in the Print box of your software program to save your settings and start printing.https://agribusiness.pk/wp-content/plugins/formcraft/file-upload/server/content/files/16270885137913---bostitch-sb1664fn-owners-manual.pdf The next time you want to print this document, you can use the Print button at the top of the screen in your software program — simply click it to print one copy using the same print settings. That’s all there is to it. The printer prints one page at a time until it finishes, delivering each printed page neatly into the printer’s OUT tray. Page 34 How to print on different paper sizes 2 Type the dimensions of the paper in the User Defined Paper Size dialog box, and click OK. Most of the time, when you print on plain paper, cards, labels, and envelopes, you select one of the standard sizes in the Paper Size box on the Setup tab of the HP print settings box. However, you’re not limited to the sizes listed. Page 35 How to print on both sides of the paper Book option The easiest way to save paper is to print on both sides. Just put the paper through the printer twice: the first time through it prints the odd-numbered pages and the second time through it prints the even. 1 Load the paper in the IN tray. Make sure that there’s no paper in the OUT tray. 2 In the HP print settings box, click the Features tab. (See “Finding the HP print settings box” on page 30.) 3 Then click Book or Tablet. Page 36 6 When the paper is properly loaded into the IN tray, flip the OUT tray down and click Continue. The printer prints the even-numbered pages on the reverse side of the odd-numbered pages. After printing, remember to uncheck the Two-Sided Printing option on the Features tab. How to create a mirror image of your document When you print a mirror image, the text and pictures are reversed (mirrored), from what you see on your computer screen. Print a mirror image when you use an iron-on transfer. Page 37 1 Load the paper in the IN tray, printable side down. If you’re printing transparencies, go to “Printing Transparencies” on page 49. If you’re printing iron-on transfers, go to “Printing Iron-On Transfers” on page 51.www.crea-solution.com/ckfinder/userfiles/files/boss-mc500-manual.pdf 2 In the HP print settings box, click the Features tab, and then click Mirror Image. (See “Finding the HP print settings box” on page 30.) 3 Print your document. The text and pictures are reversed. Hold the printout up to a mirror to see how the final product will look. Page 38 About color How to turn off color Your HP DeskJet printer prints in color when a color-capable software program is used with the printing software. Believe it or not, your color printer prints with only four colors—cyan, magenta, yellow, and black. By printing overlapping dots of different intensity and color, it creates practically any color you can imagine. The color text and pictures that you create in your documents automatically print in color. Page 39 About pictures Pictures (also called graphics) include photographs, illustrations, charts, and decorative elements. You can purchase libraries of clip art from a variety of sources or browse the Internet for what’s available there. Look through computer magazines for the names of companies that sell clip art. They’ll be happy to send you full-color pictures of their extensive offerings. For a small fee, you can have an entire roll of photos put on a CD or floppy disk. Be sure to ask your camera shop to also put a CD-viewing program on the CD with your photos. A digital camera bypasses film entirely and turns the photo into a computer file. Page 41 Beyond the Basics With the printing basics down, you’re ready for some results. Here are some ideas for printing on different paper types. Greeting cards, business cards, recipe cards, or invitations to opening night. Banners—welcome back the home team, or announce a new addition to the family. Envelopes—either one at a time or as a stack. Transparencies for that important overhead presentation. Iron-on transfers on t-shirts printed with your company logo. Page 42 Printing Cards Use your printer to print on index cards, recipe cards, greeting cards, business cards, or postcards—or any card size included in the Paper Size list on the Setup tab. You can print on other sized cards, too. If the dimensions of your card aren’t the same as those shown in the Paper Size list, see “How to print on different paper sizes” on page 34. 4 Slide the paper-width adjuster to the right until it fits snugly against the cards. Page 43 Printing Banners We encourage you to use HP Banner Paper for the very best results. When you use HP Banner Paper, your banners print with brighter color and denser blacks than if you use other banner paper. It’s easy to use, too—you don’t have to tear off those pesky perforated strips. Look for it at a large office supply store. Always fan the paper to fluff it before loading it. Page 44 6 Get the banner paper ready for the printer: a. From the stack of banner paper, tear off the number of sheets you need to print the banner. (You must have at least five sheets in the stack.) b. Tear off and discard the perforated strips, if there are any. c. Fan the stack so that the pages don’t stick together in the printer. 7 Put the paper into the lower IN tray so that the unattached edge is at the top of the stack. Insert the stack’s top edge first into the IN tray until it stops. Page 45 Printing Photographs Printing photographs is similar to printing any other color image. The main differences are paper and print quality selections. For best results when printing photographs, use one of HP’s photo papers. For a list of available photo paper products and ordering information, see page 71. 3 Load the paper as you would for normal printing. Make sure you insert the paper printable side down. 1 In the Setup tab of the HP print settings box, select a photo paper for the Paper Type. Page 46 Printing Labels You can use your HP DeskJet printer to print sheets of labels. Use only A4 or U.S. letter-sized sheets of labels. It’s particularly important to pick labels that are made especially for inkjet printers. 4 Slide the paper adjusters to fit snugly against the stack. 5 Push the IN tray back in and flip the OUT tray down. Avoid shiny or embossed envelopes, or those that have clasps or windows. (Use transparent labels instead for these sorts of envelopes. Page 48 How to print a stack of envelopes 1 In the HP print settings box, click the Setup tab, and then select the envelope you’re printing on as the Paper Size. (See “Finding the HP print settings box” on page 30.) 2 Slide both paper adjusters out. Make sure the IN tray is empty. Flip up the OUT tray for a better view of the IN tray. 3 Load a stack of up to 15 envelopes in the printer, as shown on this page. (If you’re using thick envelopes, you might need to reduce the quantity. Page 49 5 Push the IN tray back in and flip the OUT tray down. 6 Print the envelopes. About small envelopes If you’re printing on small envelopes such as Invitation A2 or C6, you’ll need to push the small slider in until it fits snugly against the short edge of the envelopes. Make sure the envelopes do not bend in the IN tray. Small slider Printing Transparencies For best results, use HP Premium Inkjet Rapid-Dry Transparencies. Page 51 Printing Iron-On Transfers When it comes to printing images, you don’t need to stop with paper. Use transfer paper to get the images from the computer document onto cloth. HP Iron-On T-Shirt Transfers are designed to work with your printer and HP ink to give you a professional silk screen look. Although 100 cotton t-shirts are a popular choice for iron-on transfers, you need not stop there.

Page 59 Print cartridges To replace a print cartridge: Each HP print cartridge is a self-contained, plug-in ink supply.

Storing print cartridges You’ll hear the cradle mechanism move, returning to the home position on the right side of the printer. 9 If the Print Cartridge light continues to blink after you install new print cartridges, check the part numbers on the cartridges to ensure you installed the correct ones. See page 59 for part numbers. Page 62 Cleaning the print cartridges To clean the print cartridges from the HP Toolbox: Cleaning your print cartridges can improve the quality of printing. 1 Open the HP DeskJet Toolbox. See “The HP DeskJet Toolbox” on page 58 for instructions on how to find it. If your printed page is missing lines or dots, perform Procedure 1 below. If your printed page contains streaked ink, perform Procedure 2. Page 63 or sn ame jstujn de d diam noft juestk ut labore qusft vol sed kitft ghocknor Procedure 2: Eliminating ink streaks Customers using HP DeskJet printers in dusty environments might occasionally experience ink streaks or smearing because of a small accumulation of debris inside the printer. This debris can include dust, hair, carpet, or clothing fibers. Ink streaking is easily prevented or corrected by doing scheduled cleaning to two areas of the printer: the print cartridges, and the print cartridge cradle. Page 64 Steps to manually clean your print cartridges and print cartridge cradle: 1 Remove the print cartridges a. Turn the printer on and lift the printer’s top cover. b. The print cartridge cradle moves to the center of the printer. c. After the cradle has moved to the center of the printer, unplug the black power cord from the back of the printer. d. Remove the print cartridges and place them on their sides on a scrap piece of paper. Page 65 2 Clean the print cartridges a. Dip a clean cotton swab into distilled water and squeeze any excess water from the swab. b. Grasp the black print cartridge by the colored cap. c. Clean the face and edges of the print cartridge as shown. DO NOT wipe the nozzle plate. 3 Clean the print cartridge cradle a. Position yourself at eye level with the printer. b. Locate the cradle that holds the print cartridges, then locate the three black, hook-shaped arms on the bottom of the cradle. c. Page 66 4 Reinstall the print cartridges a. Reinstall the print cartridges and close the printer’s top cover. b. Reinsert the power cord into the back of the printer. c. Print a test page. On the Printer Services tab of the HP Toolbox, click Print a Test Page. d. Examine the printout for ink streaking. Note: This procedure should remove all fibers that would cause ink to streak on a printout. However, fibers can be missed. Page 67 Maintaining your printer Aligning the print cartridges You must use the printer software to calibrate the black and tri-color print cartridges each time you replace or reinstall an print cartridge. This ensures that the black and tri-color inks are aligned when used together on the same line of text or within the same picture. 1 Make sure the printer is on and the Power light is lit. 2 Be sure the printer’s IN tray contains plain paper. 3 Open the HP DeskJet Toolbox. If your computer has less than 100 MB of free space, it can take longer to process your document for printing.
