EastRoyce is a pro of printer manufacturing and developing.
Every printer shipped by us is restrictly passed every test.
 Our main testing procedure is : 1> Test each circuit board after firmware is loaded. Make sure first basic test is 100% passed. |
 2> Assemble circuit board into printer enclosure, then will have a first function test of whole printer |
 3> For example, we are going to manufacture 1000pcs printers, we will need to put 1000pcs power chargers onto our aging test platform，connect them one by one to 1000pcs printers. Keep chargers plugged in power, then starts aging test, which means not only the printer itself need to be passed aging test, but also the power chargers. During the whole aging test, we will also need to do the following: ====charge all the printers until fully charged, observe the indicator color ( red color---charging sucessfully blue color--charge completed red&blue ---charging error , pick out this printer and send it to reparing center) ====when all printers are fully charged and all charge indicators turns green , will go to the next step. ====power on 1000pcs printers one by one on the aging test platform, check power indicators and power status( if any one is failed, pick it out and send it to reparing center), then keep all printers working on this platform for 4~8 hours (at least 4 hours) , if everything is OK, then those printers will be moved to the next step. Otherwise send them to repairing center. |
4>Start second function test of the whole printer. at this step, we will also test every cable. When it comes to the end of step 4>, you could see that Printer passed test. Charger passed test. Battery passed test. Cable passed test. Then move to packing.... (Compared with some other suppliers, they may not test the battery one by one ,they may not test the charger one by one, they may not test the cable one by one) |
