Run the Message Pro software and insert the SD Card Reader with an SD Card into the USB Port of PC. 3. The system will synchronize the corresponding files into the SD Card. b. Upgrading Procedure 1. Insert the SD Card into the slot of U2 Controller. 2. Keep pressing the Remote On / Off button, and power on the U2 Controller. 3. Press Enter to select the corresponding files for upgrading. 4. Go to U2ALL to upgrade xxxxxxx.tpu file. 5. After finishing the upgrading, please restart the U2 Controller to access into U2 main interface. Ⅴ-2: Boot version upgrading 1. Power on the U2 printer and access the message browser mode. 2. Press "Function " to access boot upgrading mode. 3. Select xxxxxx.tpp file for upgrading. Ⅵ. Editing Logo When you import a Logo, please be aware of the Logo height restriction due to different Line Modes. One Line: The height of the logo 75 pixels Two Lines: The height of the logo 37 pixels Three Lines: The height of the logo 25 pixels Four Lines: The height of the logo 18 pixels

7 Under 300 DPI condition, Logos can be printed with original size. If you do not use, please go to "Function > Printing Setup > PringHead >Resolution" and choose 300 DPI; If the resolution is not 300 DPI, first you may calculate a value like x=current DPI / 300, then use Windows Paint software to open the Logo, choose "Image > Stretch/Skew " and input the value of x to Horizontal column. Please see below example for reference: If you want to print a balck square with 400 DPI, please set up the Logo parameters as follows: Ⅶ. How to connect U2 printers with external & Photocell Ⅶ-1.

9 Ⅷ. U2 FAQ Solution:a) Use lint-free soft cloth to clean the nozzle; b) Change a new The first step for perfect printing like below image is to set a guide bar on the conveyor. The following examples are possible printing problems due to wrong settings. Ⅷ-1. Incorrect conveyor speed setting The conveyor speed must be stable in order to produce a perfect printing; otherwise, you may need to install encoder. a. Conveyor Speed setting is too fast b. Conveyor Speed setting is too slow Solution:Press FUNCTION 5" to set up correct speed. Ⅷ-2. Incorrect DPI setting If the DPI setting is different with actual DPI, you'll get below printing even if you've installed. Solution:Press FUNCTION 5" to set up correct Pulse/Cycle and Diameter based on the. Ⅷ-3. Incorrect printing direction setting You'll get below printing image in case you've set incorrect printing direction: Solution:Press FUNCTION 5 to choose correct printing direction. Ⅷ-4. Build up on the nozzle

10 Ⅸ. U2 Performance Ⅸ-1. Test performance of U2 For printing variables, It's highly recommended to test the U2 in order to check if its performance can catch up with the clients requests. Here are the key factors we need to know for tests. 1). Conveyor speed 2). Length of printed substrate 3). Min. Gap between substrates 4). Length of printed message 5). Contents and layout of printed message 6). Printing Interval 7). DPI info 8). Printing Delay 9). Detailed application description If there is no missing prints, it means the performance of U2 can meet with the client request. Ⅸ-2. Printing speed of U2 1. DPI (Resolution): Dots / Inch 2. f (Hz) (Frequency): Dots / Second 3. V max (Speed): Under the speed, there is no distortion of printed messages 4. Speed Formula: V max = f (Hz) / DPI * m/min (For U2 printing system, Max. f (Hz) is 15 khz) 5. DPI Formula: DPI = Pulse/Cycle * 25.4 / Diameter / π Pulse/Cycle Unit: PPR Diameter Unit: mm ON) 6. Minimize the build-up on the nozzle surface ( Drop weight (ng) 6.5 K 8.5 K f (Hz) It is highly recommended to avoid the working frequency is during 6.5 khz ~ 8.5 khz, in order to minimize the build-up on the surface of the nozzle. 7. Relationship between DPI & Speed, and DPI & wheel diameter NUMBER Relation between resolution and conveyor speed For U2 RESOLUTION WHEEL DIAMETER (PULSE/CYCLE:2500) CONVEYOR SPEED MM Inch Meters/Minute Feet/Minute 600 DPI m/min Feet/Min 550 DPI m/min Feet/Min 500 DPI m/min Feet/Min 450 DPI m/min Feet/Min 400 DPI m/min Feet/Min 350 DPI m/min Feet/Min 300 DPI m/min Feet/Min 250 DPI m/min Feet/Min 200 DPI m/min Feet/Min 150 DPI m/min Feet/Min 100 DPI m/min Feet/Min 50 DPI m/min Feet/Min

11 Ⅸ-3. Printing length of U2 Horizontal: 30,000 dots Vertical: 150 dots per U2 For example: With 300 DPI, the Max. length of the printed message (L): L=30000 dots / (300 dots / inch) =30000 / 300 * 25.4 / 1000 m =2.54 m So no matter whichever DPI users choose, the ink consumption is the same and just the printed length is different. See below example for your reference: For 300 DPI: Printed length: A mm Ink consumption: B Dots For 600 DPI: Printed length: A/2 mm Ink consumption: B Dots From your view, 600 DPI will show you darker printed image! Ⅹ. U2 installation Ⅹ-1. For U2 Controller Proposal: a). It's not recommended to have U2 Controller share the power with other industrial equipment, in order to avoid power noise. Also, an online UPS system is highly suggested. b). U2 Controller needs to be grounded properly in order to avoid static electricity. Ⅹ-2. For U2 bracket Proposal: a). It's highly recommended that U2 bracket needs to be apart from conveyor, in order to avoid bubble generated inside the bladder due to vibration, so a stand is necessary. b). It's also essential to get a guide bar to ensure the distance between nozzle and printing surface less than 3 mm. c). The distance between bracket holders is shorter, the firmness is better.

12 Ⅹ-3. For U2 (Option) Proposal: a). Preferably install right under the U2 Printhead b). Wheel surface must be vertical with Conveyor belt c). Tension direction should be positive If the conveyor belt is not flat enough to install directly, we may have following two substitutes. 1). If the printed carton is long and heavy enough, It'll be available to get the undistorted signal once the wheel is attacked by the coming carton. 2). In case the carton is too small and too light, there is another solution to get the accurate signal. For any conveyor belt, there must be a main wheel and secondary wheel. You need to make a flat wheel whose diameter is equal to: [diameter of the main wheel + 2 * thickness of the belt]. Then, please embed an axletree into the right center of the main wheel and the man-made wheel. After that, you can install on the man-made wheel. This is the proper way to ensure the speed read by the is the same as the actual speed of printing. D Ⅹ-4. For U2 external Photocell (Option) If you wanna adjust detecting distance, you can rotate the adjusting screw as Figure showed above. (If you want to lengthen detecting distance, please rotate the screw to be "max" direction as it shows you; if you wanna shorten it, please rotate the screw to "min" direction as it shows you) The range is from 0 to 10 cm. Adjusting screw It's highly recommended to adjust the printing position via Photocell location adjustment, instead of adjusting Delay! Ⅹ-5. For U2 BIS (Option) It's flexible to mount the BIS holder anywhere as long as the ink level (vertical distance bewteen nozzle and BIS nozzle) should be kept 45 mm, no matter whether you choose Side printing or Downside printing. Also, the tubing that connect the PEN Cartridge and bulk ink bladder is forbidden to be forced by pressure and strength, otherwise, the bottom of Cartridge may not contact well with Cartridge holder, that probably casues the issue of ISD damaged. For 370cc BIS, it's highly recommended to connect bulk ink bladder and PEN Cartridge after several prints, in order to avoid air accessing. Ⅹ-6. Binding cables for U2 After finishing the installation, please also bind all the cables. Pay attention to the tension (not too tight or too loose) when binding cables.
