  • Page 14: Section 2 Adjusting Sensors And Printout

    SECTION 2 ADJUSTING SENSORS AND PRINTOUT In this section we will cover sensors locations and their function, including cover open sensor, black mark sensor, gap receive sensor and ribbon sensor. When the printer is not working properly, you need to adjust the gap detection during maintenance.

  • Page 15: Cover Open Detection Sensor

    1.1 Cover open detection sensor Remark: The cover open detection sensor is a switch-mode sensor assembly, in order to detect whether the print head is open or closed. When the print head is open and the printer is on, the printer will give an error LED alarm, which indicates the print head is open. Please note that this sensor will not detect whether the top cover is open or not.

  • Page 16: Gap Sensor

    1.2 Gap sensor Remark: The gap sensor works together with the reflective sensor. They have two functions: 1. Media sensor = “gap” and “reflective” detection methods. 2. Black mark position detection (media sensor = reflective detection method) As for function 1, users have to align the reflective sensor with the reflective sensor receiver component with the black mark sensor component.

  • Page 17: Ribbon Sensor

    1.3 Ribbon sensor Remark: When the ribbon is used up, the sensor will detect it and raises alarm via the LEDs. When installing the ribbon, be aware of the in/out face.

  • Page 18: Cutter Installation

    1.4 Cutter installation Rotatable connector Plate cutter Remark: Remove the ratable plate and install the cutter connector to the J2 connector, and then install the cutter. You could change the cutting mode via the tool: full cut or partial cut.

  • Page 19: Peeler Installation

    1.5 Peeler Installation connector peeler Remark: Remove the ratable plate and install the peeler connector to the SJ6 connector, and then install the peeler. You could enable or disable the peeler function via the tool.

  • Page 20: Part Two Calibrate Printout

    Part Two Calibrate Printout The printer needs to be calibrated to reassure its precision. In this part, calibration method will be explained. You may refer to it when you come to maintenance, repair or changing parts, Note：In this part we mean to calibrate the print head spring, so that we could obtain ideal printout.

  • Page 21: Evaluate Calibration Result

    2.1 Evaluate Calibration Result See the pictures below, there are two kinds of printouts: Picture A shows normal printout; picture B shows abnormal printout. During calibration actual result is subject to actual conditions. 1) When the pressure is higher than normal, media jam, ribbon jam, stopped printing or etc. issue(s) may happen.
  • Page 22 Note that printing speed and printing density do affect the actual printout. Change of printing density will affect more in the printout than that change of printing speed. Therefore, during printout calibration, please set printing speed and printing density to median value and not to change it again.

  • Page 23: Section 3 Diassembly And Assembly

    SECTION 3 DIASSEMBLY AND ASSEMBLY This section describes procedures for disassembling the main components of Dascom DL- 210. Unless otherwise specified, disassembled units or components can be reassembled by reversing the disassembly procedure. Therefore, no assembly procedures are included in this section. Switch off printer and unplug from power outlet before disassembly.
  • Page 24 5) Check whether the paper is loaded properly (not too loose, not too tight). 6) Please do not place anything on the cover of the printer, or slant the printer when you maintenance or the printer prints. 7) During the maintenance, be careful not to drop any part or screw into the printer. 8) Keep the printer parts (screws, etc.) on a safe place.
