Learning How to Operate the Printer

To operate the printer, you need to understand:

Power light The Power light helps you determine when the printer is on or off, or if there is a problem with the printer.

Feed/Pause button The Feed/Pause button allows you to feed out media, pause the printer, and print a hardware configuration label.

Understanding the Power Light

Use the Power light to monitor the status of the printer:

Over-Temperature If the printer overheats, the Power light flashes red and the printer stops. Do not try to troubleshoot or adjust the printer—just allow it enough time to cool down and it will resume operation on its own.

Media or System Faults If the Power light turns red or orange and remains on, your printer is experiencing a media or system fault. For help, see Chapter 4, “Troubleshooting.”

Loading Media Into the Printer

In addition to loading roll media in the printer, you can:

Use the peel-off option.

Load fanfold media.

You can load media with the printer power turned on or off. The following procedures for loading media assume that you have turned on the printer. Refer to the EasyCoder 7421 Printer Setup Guide for instructions on loading rolls of media.

Using the Peel-Off Option

Use the peel-off option in printing applications where you want to apply labels to a surface immediately. After printing a label, the printer presents the label with the backing removed.

Note: You should find a small label with a three-digit sensitivity number printed on it attached to your roll of media or a 15-digit number stamped on the side of the media roll. Save this information. You will need it to set the correct media sensitivity number. For help, see “Setting the Media Sensitivity Number” in Chapter 2.

Note: Intermec does not recommend using fanfold media with the peel-off option.
