SECTION 1 CONTROL PANEL FUNCTION In this section, we will talk about the control panel and power switch functions and their combinations’ functions. Part One Control Panel Function 1.1 Panel functions and button The printer has three LEDs and one button on the control panel.
Feed Key Operation Under ZPL/EPL mode, press Feed Key once, feed one piece of label; Under ZPL/EPL mode, hold down Feed Key without release, feed labels continuously. 1.2 Feed Key & Power Switch Function Purpose Operation Hold down Feed Key and switch on printer till Power Print self-test LED blinks once, buzzer beeps once.
Page 9
Printing example: 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ Press the FEED button one time to feed the last line after the printer stops printing so as to return to the normal mode.
1.3 Parameter Setup Settings A CD comes along with printer. The CD contains POS & label printer setup tool for configuring printer. Or, please find the latest setup tool on Dascom website: www.dascom.com Read the help file carefully before using the setup tool. Please click “Help” button below for more information.
If power is switched off during the process, the printer may be damaged afterwards. (1) Preparation USB cable, 24V power adapter, DL-210 setup tool, firmware file. (2) Connection Connect printer and host with USB cable firmly. Check the Device Manager, if connection is successful, “USB printing support”...

(3) Enter Update Mode ① Lift up top cover and turn up print head mechanism Print head mechanism ② Hold down Feed Key and switch on printer simultaneously. Release Feed Key once powering on, the printer will beep once. ③ Status LED on, printer enter upgrade mode. (4) Upgrade Firmware ①...
Page 13
③ After loading the firmware, the Power LED, Error LED and Status LED blink. ④ When the printer beeps twice, and the three LEDs are on, turn the printer off. ⑤ Mission complete.
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.
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.
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.
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.
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.
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.
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.
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.
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.
1.2 Disassembly Procedure This section describes procedures for disassembling the main components of the printer. Since re-assembling the printer can be done by simply performing the disassembly procedures in reverse order, this chapter does not describe the assembly procedures. If necessary, special notes on re-assembling or adjusting a component are given at the end of each procedure.
