  • Hand Held Printer EBS 250

    The innovative HandJet®️ EBS-250 combines the proven success of our EBS-230 production line ink-jet system and adds a unique, wireless interface.

    It signals a new era in portable, hand-held ink-jet coding, replacing antiquated hand coders such as stencil machines, stamps and roll coders, which are laborious and expensive in use and problematic with ink management.

    Weighing in at just under two pounds – including its on-board rechargeable battery and ink cartridge – the HandJet®️ EBS-250 is the ultimate in lightweight, compact coding.

    With its patented print technology, the unit improves and economizes ink management to make traditional manual coding methods like stencil marking, hand stamps and roll coders virtually obsolete.

    By using solvent-based inks in an array of colors, the HandJet®️ EBS-250 provides fast, clean printing on a variety of corrugated materials, in addition to metal, glass and plastic substrates. The unit’s high-volume ink-jet cartridge efficiently provides up to 100,000 characters with a dot matrix of 7×5.

    The HandJet®️ EBS-250 uses a simple MicrosoftTM Windows®-based program to format and transmit messages that are easily created on a personal computer. Messages can consist of alphanumerics and logos from Windows® fonts and symbols, as well as diacritical characters.

    The hand-held system minimizes energy consumption to print for up to 50 continuous hours thanks to its rechargeable Li-ion battery – and recharging takes only two and a half hours.

      • This releases the pressure from the ink system
    • Re‐attach the cartridge
      • This prevents dust, dirt or air from entering the back of the unit
    • Store the unit with the cartridge attached
    • First take care that the Bluetooth module is connected and that the printer is switched on.
    • Open the menu “Guides / Network configuration” and follow the instructions.
    • When you still cannot communicate with a printer, check the COM port setting.
    • Open the network window (menu “Tools / Printer network”). In the left upper corner you see the program’s setting of the COM port. Please open the list and choose another port if available.
    • Start the HandJet® in the normal way but keep holding the “Print On/Off” button until all LED’s (except “Charge”) are lighting.
    • Now press the “F” button once. When you release the “Print On/Off” button the HandJet® begins immediately to print a test text continuously with high printing speed. Pressing the “Print On/Off” button once more it prints a test text slowly with high intensity. Next pressing prints the same test text with low intensity. Pressing once more the HandJet® is silent.
    • Pressing once more starts printing continuously only nozzle 1. Next pressing starts nozzle 2, and so on until nozzle 16. First only the nozzles on the right side will be fired, then only the nozzles on the left side. The actual nozzle number is shown in the display.
    • Next pressing starts printing continuously with all nozzles. Next pressing starts again with the first test print.
    • To adjust the dot size, remove the rubber plugs at the side of the HandJet® and adjust carefully the Torx-screws.
    • To leave the service mode, switch off the HandJet® in the normal way (“F” button and Release key).

    If the HandJet® cannot be switched off, remove the cartridge and cross the cartridge contacts in the rear plate with a wire (e.g. bended paper clip) until the HandJet® goes off.

    You can create an own graphic directly in the PC program.

    For this open the bitmap editor.

    An existing logo can be inserted as follows:

    • The logo should be available as black and white bitmap with the suitable dot-height, max. 16 dots.
    • Then start the program Gfx-Maker, which you find in “C:\program files(X86)\ EBS Printers\
    • EBS-250\Graphics\GFX Maker”
    • Click on “Graphic”, “Load bitmap”, select your bitmap file.
    • In the following window insert the password ” e25pix” + Enter, then click on “Convert”.
    • The dot-graphics appears in the window and can be stored with “Save to EBS-200 format” (don’t forget to give a file name).
    • In the EBS250 PC program the image can be inserted with “File / Insert image”.
    • The character rotation works only with Windows fonts, not with system fonts.
    • After the choice of a Windows font appears in “Parameters 2“ the drop-down list “Rotation“.
    • Choose the rotation angle and enter the message.
    • If the message does not fill the entire printheight, you can additionally select the alignment.

    Select from the font list “Spec 7“ or “Spec 16“. The symbols appear after typing the corresponding capital.

    Spec 7.
    Spec 16.

    If the nozzle plate is dirty, clean it by spraying solvent on it. Hold the printer face down spray from below, that no solvent (mixed with ink) can flow into the unit or onto the guiding rolls.

    • In the next step use the purge function. Hold the HandJet® over a vessel or over a cloth.
    • When the HandJet® is switched on, press the trigger button three times and hold it with the third pressing. After a second the HandJet® beeps short and fires ink out of all nozzles for a short moment. Keep holding the trigger button, after one more second delay it starts firing ink continuously out of all nozzles until you loose the button.
    • If some dots are still missing, it is necessary to remove the nozzle plate for cleaning.

    When you use special inks, e.g. pigmented inks or fast drying inks, it can happen that due to pigments or ink rests nozzles will be blocked. In this case it is recommended to use a cleaner cartridge daily. Use the purge function to flush out old ink rests. This is also recommended when a HandJet® will not be used for longer time. You must take care to use a cleaner which is adequate to the ink base.

    • The cartridges are encoded, and because of this only original EBS cartridges can be used. Refilling is not possible.
    • Before you change a cartridge, shut off the HandJet®! Otherwise the encoding can be destroyed and the cartridge will not be accepted anymore from the HandJet®.
    • To remove the cartridge, turn it counterclockwise and pull it from the HandJet®. The new cartridge matches only in one position and must be locked with a clockwise turn.
    • After power on the new cartridge will be verified from the HandJet®, in the mean time the Power-LED blinks.
    • After 10 seconds the Power-LED and the Print-LED blink fast and the HandJet® beeps once, if the new cartridge is okay and is accepted. In case of a wrong or empty cartridge the Error-LED blinks. In this case please check also the date setting of the HandJet® and correct it if necessary.
    • In this case please click on “Retrieve”, under the Info-tab you will find an error message.
    • If there appears “Empty bottle” or “Bottle too old”, please use a new cartridge.
    • In case of “Bottle too old” replace expired cartridge with a fluid cartridge that’s not expired
    • “No bottle” appears when there is no cartridge connected, or when the electrical contacts in the HandJet®’s rear plate are dirty. Check also if the three locking pins on the cartridge are dirty, these are also electrical contacts.
    • “Bottle already cancelled” appears when the cartridge transponder is deleted. This can happen when a cartridge is connected or disconnected while the HandJet®is switched on.

    Click in the Guides menu on Network configuration.

    The network window appears and a configuration dialog. To add more printers later, you can also

    click here.

    All printers can be switched on at the same time. In the network window appears after each recognized and added printer an entry “Handjet® with its serial number. After finishing the network highlight this printer in the list with which you want to communicate.
