3 Using Print Materials This chapter will help you understand types of paper you can use with this printer and how to properly load paper in the tray for the best print quality.
Choosing Paper and Other Materials You can print on a variety of print materials, such as plain paper, envelopes, labels, transparencies and so on. See “Paper Specifications” on page 7.21. To get the best possible print quality, use only high-quality copier-grade paper. When you choose print materials, consider the followings: • Desired outcome: The paper you choose should be appropriate for the project. • Size: You can use any size paper that fits easily within the paper adjusters of the paper feeder.
Sizes and Capacities Input Source/Capacitya Size Tray Manual Feeder Letter (8.5 x 11 in.) 250 1 Legal (8.5 x 14 in.) 250 1 Executive (7.25 x 10.5 in.) 250 1 Folio (8.5 x 13 in.) 250 1 A4 (210 x 297 mm) 250 1 B5 (182 x 257 mm) 250 1 A5 (148 x 210 mm) 250 1 A6 (105 x 148 mm) 250 1 - 1 1 1 1 1 1 - 1 1 Letter (8.5 x 11 in.) A4 (210 x 297 mm) - 1 1 Card stocksb - 1 Plain Paper 3 Envelopesb No. 10 (4.12 x 9.5 in.) Monarch (3.87 x 7.5 in.
Guidelines for Paper and Special Materials When selecting or loading paper, envelopes, or other special materials, keep these guidelines in mind: • Attempting to print on damp, curled, wrinkled, or torn paper can cause paper jams and poor print quality. • Use cut-sheet paper only. You cannot use multi-part paper. • Use only high-quality, copier grade paper for the best print quality. • Do not use paper that has been already printed on or that has been fed through a photocopier.
Selecting the Output Location The printer has two output locations: the rear output tray and the top output tray. Top output tray Rear output tray 3 To use the top output tray, be sure the rear output tray is closed. To use the rear output tray, open it. Notes: • If paper coming out of the top output tray has problems, such as excessive curl, try printing to the rear output tray. • To avoid paper jams, do not open or close the rear output tray while the printer is printing.
Printing to the Rear Output Tray (Face up) The printer always prints to the rear output tray if it is open. Paper comes out of the printer face-up, and each time a sheet of paper comes out, it falls down from the printer. Printing from the Manual Feeder to the rear output tray provides the straight paper path. Opening the rear output tray might improve the output quality with the following: • envelopes • labels • transparencies To open the rear output tray: 1 Open the rear door by pulling it down.
2 If you do not want to print to the rear output tray then close the tray. The pages will stack on the top output tray. 3 Loading Paper Proper paper loading helps prevent paper jams and ensure trouble-free printing. Do not remove the tray while a job is printing. Doing so may cause a paper jam. See “Sizes and Capacities” on page 3.3 for acceptable paper size and capacities for each tray. The paper level bar on the front of the paper tray shows the amount of paper currently in the tray.
Using the Manual Feeder If you select Manual Feed in the Source option, you can manually load paper in the manual feeder. Manually loading paper can be helpful when you want to check the print quality after each page is printed. If you experience a paper jam from the tray, load one sheet of paper at a time into the manual feeder. 1 Load the print material in the manual feeder with the print side up. Adjust the paper guide against the print material without bending the paper.
In Manual Feed mode, you can’t cancel a print job by pressing the Cancel button. To cancel a print job in Manual Feed mode: 1 Turn the printer off. 2 Double-click the icon at right bottom of the window. 3 Double-click this icon to view the queue of the print jobs. 3 Select a job you want to cancel. 4 For Windows 9x/Me, select Cancel Printing from Document menu. For Windows NT/2000/XP, select Cancel from Document menu. 5 When the jobs are removed from the list. Turn the printer on.
Printing on Envelopes Guidelines • Only use envelopes recommended for laser printers. Before loading envelopes in the manual feeder, make sure that they are undamaged and are not stuck together. • Do not feed stamped envelopes. • Never use envelopes with clasps, snaps, windows, coated lining, or self-stick adhesives. These envelopes may severely damage the printer. 1 Open the rear output tray. Load the envelopes into the manual feeder with the flap side down.
3 When you print on envelopes, you must select Manual Feed for Source from the software application, and then select the correct paper size and type. For details, see page 4.6. 4 Press the Cancel button to start feeding. Note: Please be careful when you open the rear cover. The inside of the printer maybe hot. 5 Printing is started.
