  • Page 60: Media Guides

    By comparing the detection of light/no light with the paper type setup (black mark/gap paper/plain paper), the firmware can determine the position of the labels or similar along the media path and also detect out-of-media conditions. EasyCoder PD41/PD42 Printer Service Manual...
  • Page 61 For more information, see the printer user’s guide. You can also adjust the sensor with Fingerprint commands. For help, see the Intermec Fingerprint Command Reference Manual (937-005-xxx). To replace the label gap sensor module Note: Before replacing the module, check that there is no dirt, dust, adhesive residue, or stuck labels that blocks the light between the two sensors.

  • Page 66: Extending The Life Of The Printhead

    • When using preprinted labels or labels with some type of varnish or non-standard top coating for direct thermal printing, use original Intermec labels or inks recommended by leading manufacturers of direct thermal media. The labels must not contain any aggressive substances such as chloride or grinding substances such as titanium dioxide.

  • Page 67: Adjusting The Printhead

    Adjusting the Printhead The printer is factory-adjusted for full-size media width. When using media less than full width, Intermec recommends that you adjust the position of the printhead balance boxes so an even pressure is applied across the media. A poorly adjusted printhead pressure may be detected by a weaker printout on either side of the media path.

  • Page 71: Rewinder Module

    This section describes the optional internal rewinder required for peel-off (self-strip) and batch takeup operation. The rewinder module is an optional device for the EasyCoder PD41/PD42 printer. The printer is prepared with belt, pulley, and gear train for driving the rewinder using the same stepper motor that also drives the platen roller and transfer ribbon rewinder.

  • Page 73: Label Taken Sensor (Lts)

    Label Taken Sensor (LTS) This section describes the Label Taken Sensor, which is a standard feature on the EasyCoder PD41/PD42 printer. The purpose of the Label Taken Sensor is to detect if a label has been removed after printing and—if not—hold the printing of the next label. It works equally well when the media is manually torn off after printing as when the labels are automatically separated from the liner.
