Approximately Once we had confirmed the strength of the weld, we would return the deformed piece to normal. Thus we are forced to destroy the welded spot in the course of the inspection. This is why the need for non-destructive inspection, which can verify welded parts without causing damage, is on the rise, explains Hiromasa Takahashi of the Mechatronics Engineering Solution Department, Corporate Manufacturing Engineering Center, Toshiba Corporation.
At the first stage, the processes of locating the weld, applying the couplant contact catalyst and operating the inspection probe must all be done by human beings. To obtain an accurate measurement, the inspection probe that emits the ultrasound is required to be applied to the welded part at an ideal angle. At the initial stage of the invention, knowing how to do that required a considerable degree of skill.
All of this made inspections extremely time- and labour-intensive. That was why the next challenge to be tackled in non-destructive inspection technology was creating structures for automating spot welding inspections through robot control. This was normally achieved through manual techniques, so finding a way to maintain that parallelism automatically was a hurdle. However that had a drawback because it needed several repeated measurements, which took at least 30 seconds.
After going through trial and error with a number of methods, they finally arrived at a solution: the tilt estimation engine. Through this, we are able to shrink inspection time from seconds for human beings to approximately 7 seconds. The consensus of the development team is that mere automation is meaningless unless it also produces higher speeds than manual processes can manage.
The Gap Sensor is indicated by the straight arrow. The Black Mark Sensor is indicated by the broken arrow. The two holes on the paper sensor flag indicate the sensor position The Gap Sensor is aligned with the right hole viewed from the front of the printer.
The Black Mark Sensor is aligned with the left hole. A distinctive green arrow is embossed on the upper side of the paper sensor to identify the exact position of the sensor. The fixed sensor is located in the center of the machine. Since Toshiba TEC printers are center-fed, it is a good practice to locate the paper sensor at or near the center of your label stock. However, there are some exceptions. For example, if you are running gap labels that are 2-across or 4-across, then the gap sensor should be located somewhat left of center, preferably in the middle of the label adjacent to the central web.
Or if you are running some sort of tag stock and you are using a notch for detection, then the sensor will need to be positioned over the center of the notch that is, close to the wall of the printer.
Error Messages Printing Difficulties. What should I do? If you are using gap type labels:. Check your software settings. Make sure that you have selected the correct sensor type and that the label height dimension corresponds to the actual height of the label you are printing. Also check the vertical gap setting, which is usually about 0. Make sure that your paper sensor is positioned so that it can detect the label gap.
For single label stock, the sensor can be located at the center of the label. If you are using preprinted labels, run the printer's threshold setup. In this case also, some software packages require a different sensor setting, often labeled 'preprinted'. If you are using black mark stock:. Make sure that you have selected the correct sensor type and that the paper height dimension corresponds to the actual height of the stock on which you are printing. Make sure that the paper sensor is positioned so that it can detect the black mark.
Whenever I try to run preprinted gap type labels, I end up with a paper jam. How can I solve this problem? Different colors on a label make it more difficult for the paper sensor to determine exactly where the label gap is located. When you load preprinted or multi-colored labels in the printer, follow this procedure:.
If this happens, repeat step 3. Open the print head and reposition your labels, so that they are ready for printing. Close the print head. How can I correct this? Check to be sure that the ribbon you are using is compatible with the printer. Make sure that the ribbon is correctly loaded in the machine. Otherwise, on the other B-X and SX products, here is what to look for:. On the back side of the print block, the ribbon must pass between the two parts of the ribbon sensor.
The upper sensor is located on the back of the print block itself, while the lower sensor is located on the black plastic arm that extends from the main printer wall. The ribbon should be routed from the feed spindle, then down through the center of the print block, underneath the print head, and up to the take-up spindle.
Can I correct this problem? If you are printing in direct thermal mode without a ribbon :. Check your software settings and make sure that the print type is 'direct thermal'.
If your software package requires the use of a Windows driver, also make sure that the driver is set for direct thermal printing. If you are printing in thermal transfer mode with a ribbon :. TEC printers require the use of ribbon that loads 'coated side out'. Make certain that your ribbon is loaded correctly.
Check your software settings and make sure that the print type is 'thermal transfer'. If your software package requires the use of a Windows driver, also make sure that the driver is set for thermal transfer printing.
Check to see if there is any dirt on the ribbon spindle gears or on the ribbon motors. For the latter you will need to remove the electronics cover. Keep away from the main logic board.
My printer was running fine, but then it just suddenly stopped. Is my print head bad? Probably not. Usually this error message is simply telling you that the print head is too hot to run. Turn the printer off and allow it to cool down for awhile. When you restart it later, it should return to its normal on line mode. Once you resume printing, check the following things:. When the printer is powered up, the fan should be running. If it is not, the printer should be repaired. If the fan IS running and the Excess Head Temperature error recurs, it is likely that the printer has a bad ambient air temperature sensor.
Here again this would be a repair issue. The fan should start up once a print job is in progress. If the fan fails to respond, you may need to replace it or possibly the main processing board. If the Excess Head Temperature error reappears, it is likely that the air temperature sensor is bad.
The printer would need to be serviced. Make sure that you are running the print head at a reasonable temperature for the application.
