Troubleshooting and routine maintenance121 C How do I print on envelopes? You can load envelopes from the manual feed slot. Your application must be set up to print the envelope size you are using. This is usually done in the Page Setup or Document Setup menu of your application. (See your application’s manual for more information.) What paper can I use? You can use thin paper, plain paper, thick paper, bond paper, recycled paper, envelopes and labels that are made for laser machines. (For details, see Acceptable paper and other print media on page 17.) There is a paper jam. Clear the jammed paper. (See Paper jams on page 140.) Print quality difficulties DifficultiesSuggestions Printed pages are curled. „Low quality thin or thick paper or not printing on the recommended side of the paper could cause this problem. Try turning over the stack of paper in the paper tray. „ Make sure that you choose the Paper Type that suits the print media type you are using.

The Paper Type setting may be incorrect for the type of print media you are using, or the print media may be too thick or have a rough surface. (See Acceptable paper and other print media on page 17 and Basic tab in the Software User’s Guide on the CD-ROM.) Printouts are too light. „If this problem occurs when making copies or printing received faxes, set Toner Save mode to Off in the machine menu settings. (See Toner Save on page 26.) „ Set Toner Save mode to Off in the Advanced tab in the printer driver. (See Advanced tab in the Software User’s Guide on the CD-ROM.) „ In the Basic tab of the printer driver, click the Settings button and check the Enhance Black Printing check box.
