1. Trouble shooting Before starting to work on a problem, first we have to understand the problem Once the problem is understood, we will try to “isolate” it in order to be focus on the problem Time for action plan Implementation of the action plan The “where to start from question ? “

2. Problems with machines can be divide into 3 main causes: The machine it self The site The operator Trouble shooting

3. Working “with” the problem While working on a problem, look for “clues” on the machine, such as : Lighting \ non lighting leds (on boards) S/W messages\signals (Emergency, communication, safety) Leakages of Air\Ink Messages on the controller\drivers display Pressure on the gauges The machine level Trouble shooting

4. Don’t forget looking for clues on the machine area as well: Environment of the site (influence mainly on quality ) Existence \ absence of air exhaust system (influence the drying and the behave of the media) The way of housing the media \ ink (the right environment according to the machine documentation) Power failures on site (non stable power) Air pressure failures (low pressure) Trouble shooting

5. Operator \Local FSE as part of the problem Always verify that the operator\FSE has done all the relevant checking's and actions (Recommended to go over again from the beginning of his actions) Verify with the operator the history of the machine (recent problems, if there are some, look for connection between them) Double check with the operator \ FSE that the technical terms you are using are similar to his terms (starvation, bending-which type??….) In case of more then one operator, try to collect the most information you can get from all the relevant operators, handling the machine Trouble shooting

6. Electrical Electronics Pneumatic Ink Ink system Mechanic Motion system Quality Media Trouble shooting Dividing the variety of problems

7. Points to check while having Electrical Problems Power failures on site – Check the availability of working with UPS or adding Stabilizer to the system Check the circuit breakers (Part of machine\operators problems) Check the Voltages on the output of the relevant power supplies – 24v and 35v and the 230v input of those power supplies Check the PDU outputs (cables are well connected) Check the PDU outputs (using Voltmeter) Motion system is in Off mode – no display, check the safety system Check if all 3 phases are active with 230v (On the main filter) Trouble shooting

8. Points to check while having Electronic problem Lighting\not lighting relevant leds on boards and on 24v Power supply Messages\Notes on the S/W (Communication, emergency, IR on\off) Messages on the display of the Controller\drivers (Run, Idle, no display) Re-loading of parameters\Motorcom on drivers Loose connections – Cables (Specially on the controller and drivers), boards (CCB connection to M.B, RIP connection to the M.B) Situation of 230v Contactor (0\1) Connection on Diodes Adjustment of the 35 Power supply Temp controller – Desired Temp., high\low form current Temp. Flags to add\drop on the S/W (Auto drop rate, side prints) Values to change on the S/W (Y advance, Z tension, Measure, Set one meter point, Motorcom) Trouble shooting

9. Points to check while having pneumatic problems Check the air pressure on both gages (0.2 and 1.5 Bar) Check the air pressure on the Main compressor Check for leakages of air from: the Main tanks, pneumatic panel, pistons, pedals. In case needed, Using external gauge, check the pressure of the input to the machine (Should be between 6-8 Bar) In case the pedal works inverted, remember to push the Reset button No pressure at all – check the safety, activation of one of the emergency ropes Trouble shooting

10. Points to check while having Ink problems Check the Expiration date of the batch Check the housing of the ink (according to the specifications on the machine documentation) Remember the option of clean solvent as flushing way ( for single head- using glass siring or for system cleaning using main tank full of solvent ) Trouble shooting

11. Points to check while having ink system problems pressure on both gauges Amount of ink in the main tank Is the main tank is “fat” Ink\air filters Valves are working? (visual red light) CCB demands ink when needed ? (Green led is lighting according to the level inside the secondary tank) Air leakages from main tanks Connection of Jet 310 on the system board and on the Pneumatic panel Trouble shooting

12. Points to check while having Mechanical problems Level of the machine Linear bar adjustment Printing table adjustment Greasing of the linear bar (throw the head carriage plate nipples) Trouble shooting

13. Points to check while having Motion system problems Safety (activation of one of the emergency wires) Proper Parameter loading Wires going inside the Controller\drivers Message on the display of the controller\driver Communication between the controller and the computer Connection of the Com cable In the computer Well connection of Jet 308 (from the RIP to the system board, on the top connection of the board) Trouble shooting

14. Points to check while having Quality problems Environment of the site (Temp. and humidity) Situation of the Printing heads (Using Nuzzle test or paper checking) Registration of the machine (if needed, re-adjust, Left\Right, X and Y alignments) Media problem ? Check different media if possible, incase of over spray, use two strips of masking tape on both sides, Ink problems? Try flushing heads or the whole ink system using clean solvent Electronic problems – Flat cables, voltages on diodes, CCB’s Trouble shooting

15. Points to check while having problems with media Wrinkles – Adjust the pistons, according to the current media, check the level of the machine – if needed, level it again, check the necessity of Teflon sheets (add or remove ), check the influence of the IR system, Over spray on media – use two strips of masking tape on both sides of the media In case of static problems- check the humidity in the site, clean the head carriage base, avoid auto cleaning during printing, if you choose to use it any way, do it manually and after the cleaning, wipe the head carriage base well. Media melting – Low the IR temp. Media shifting – Use the media lockers supplied with the accessories Trouble shooting

16. Summary of all problems: Lets hope we wont face them …
