Loading Results. The smooth backing of the ribbon protects the printhead from wear. For Direct Thermal printing, do not load ribbon in the printer. Place the roll on the Ribbon Supply Spindle l and push it on all the way.

Pull the end of the ribbon over the Ribbon Sensor k , under the Printhead assembly f , and up over the Ribbon Guide Plate m. Wind the ribbon onto the Take-up Spindle n for several turns in a clockwise direction. As you close the Printhead Assembly, keep the ribbon snug and free of wrinkles, and in line with the guide mark near the left edge of the Ribbon Guide Plate. When the printer is turned ON, a Power ON Self Test is performed which checks the status of the electronic system and controls within the printer.

Additional operating parameters are determined by the type of media being used and the position of the Media Sensor located behind the Platen and under the media. This type of media has some type of physical characteristic notch, black mark, gap between die-cut labels, etc. The Media Sensor must be properly positioned to sense these indicators. If you are using other software to drive your printer, refer to the instructions provided with that software.

To properly position the Media Sensor o , refer to Figure 6. Look through the side of the print mechanism and locate the Media Sensor Positioning Lever p. The glow of the red LED through the media can help to accurately position the sensor. Insure the media and ribbon are properly positioned within the print mechanism.

After an initial time period when the Power ON Self Test is performed, the printer will feed out media while calibrating the label length, then print a configuration label.

Check the current configuration printed on the label and note any parameters which must be changed to insure the printer fits your application.

For information on changing the configuration for your specific application, refer to Appendix A. A visual check of the label also provides an indication of the print quality. Media width and media thickness vary from one application to the. The deluxe front panel features a Liquid Crystal Display LCD that provides both printer status information and configuration option menus.

Refer to Figures 8 and 9 to locate the keys and LEDs discussed in this section. The FEED key forces the printer to feed one blank label. If you press the FEED key while the printer is idle or paused, a blank label is fed immediately. If you press the FEED key while the printer is printing, one blank label is fed after the completion of the current batch of labels. Once the blank label has been fed, pressing the FEED key again will feed a second label.

The first time you press the PAUSE key, any partially printed label is completed; then the printing process is stopped. If no label format is printing, then the next one to be printed is canceled. The printer discards all of the label format data it has received, and returns to the idle state. When an error occurs that causes an interruption in the printing process, the LED acts as follows:. No printing occurs when the printer is in the Peel mode of operation and the Peel option is not installed.

Refer to the Printer Configuration section of this guide to configure the printer for your application. In the process of clearing an error, open and close the printhead then take the printer out of PAUSE. The printer will begin the auto-calibration process if all errors have been cleared. The printer automatically determines the label length, and media and ribbon sensor settings. When non-continuous media is sensed, the calibration process is followed by the label length calculation.

Once the label length is determined, the media feeds to the rest position and stops. The results of this calibration are stored in the printer's memory and are retained even if printer power is removed. These parameters remain in effect until the next calibration is performed. As long as the printhead is closed, a calibration may be performed. Calibration may clear error conditions that prevent media movement. Ribbon and media error conditions are cleared by calibration, unless an out-of-ribbon or out-of-media condition exists.

No front panel calibration control is available. Table 1 provides a recommended cleaning schedule. Do not use harsh, abrasive cleaning agents or solvents. If necessary, a mild detergent or desktop cleaner may be used sparingly. Inconsistent print quality, such as voids in the bar code or graphics, may indicate a dirty printhead. For best results, perform the following cleaning procedure after every roll of ribbon. In this way all label formats, images, and all temporary parameter settings stored in the printer's internal memory will be saved.

Open the Media Compartment Door. Remove the media and ribbon if present. Raise the Printhead Assembly by hand and, using a cleaning swab soaked in alcohol, wipe along the printhead q print elements from end to end.

The print elements are located within the brown strip just behind the chrome strip on the printhead. Allow a few seconds for the solvent to evaporate.

Rotate the platen roller r and clean thoroughly with a cleaning swab soaked in alcohol. Reload media and ribbon, close the printhead assembly, close the Media Compartment Door, and continue printing. Refer to Figure The Media Sensor o and Ribbon Sensor k should be cleaned on a regular basis to ensure proper operation of the printer.

Brush or vacuum any accumulated paper lint and dust away from the sensors. The Cutter Module requires periodic cleaning to remove paper dust and gummed label residue. If labels are not being cut properly, or if the cutter jams with labels, this is an indication that the cutter probably needs cleaning.

The cleaning frequency depends on your application and the type of media you use. Steps 4 and 5 detail the method of removal of the Cutter Module from the printer.

This portion of the procedure will only be required when there is an extremely heavy buildup of adhesive residue. Turn the AC power off and unplug the printer power cord. Remove the thumb screw and lift off the Finger Guard and Catch Tray if used. Use a 3 mm Allen Wrench to remove the cutter mounting screw. Carefully lift the Cutter Module up and away from the printer. Remove all paper and label residue from the cutter blades and housing. The cutter blades are very sharp. Take great care in the following step to insure personal safety.

Use cotton swabs soaked with a citrus-based cleaner Goo Gone to remove all adhesive residue from the cutter blades.

While cleaning, rotate the cutter motor to access the entire length of the moveable blade. Install media, then close and latch the Printhead Assembly.
