Noritsu ошибка 6073 synchronous sensor error

Добрый день форумчанам! Чувствую что меня скоро забанят наверное за частые вопросы, но все же нужна ваша помощь. Сегодня утром пришел на работу, сделал утренний тест, вышел с оттенками красного (из прошлых опытов знаю что это красный АОМ), решил поменять местами ближний и средний АОМы тест вышел бирюзовым, но до черного, в итоге машина настроилась (через пару минут полз в зеленый), соответственно зная что на том месте стоит АОМ с красного цвета, сделал вывод что это таки АОМ. Но думаю пока еще чуть держит цвет по быстрому отпечатать 1 заказ (60 штук), утром успел взять срочку. Отпечатал заказ 10 на 15, вышел немного желтовато-зеленоватым, но фотки с мообильного телефона так что в целом подоли, заменил бумагу для печати 20 на 30, запустил фотку на печать машина отрезала бумагу и выскочила ошибка 6073 Synchronous sensor error (без дополнительных индексов), лист вышел белым, а лазер начал нагрев (5минут). После нагрева решил запустить еще раз 20 на 30, вышло также более менее нормально как и весь заказ. Через 2 минуты запустил еще 1-ну 20 на 30 она вышла фиолетовым оттенком, запустил дейли сетап вышел в зеленом оттенке с поолосками. Все изобюражения прилагаю. Реши сделать фото, все по порядку, утренняя настройка 1-й тест, затем 2 теста после смены ближнего и среднего АОМов, затем фото после ошибки (но второе, первое вышло нормальным), и затем тест после отпечатка в фиолетовом цвете. На фото в фиолетовом цвете есть пару тонких желтых полосок. они увеличены на 2-м фото.

Foto Tehnika and Dave are definitely on the right track.  Almost all the laser decks that come into us for rebuild, have this failure.

The synchronous sensor errors 6073 and 6074 refer to readings that photosensors are making all the time the laser deck is in action.  In the 30XX family, there are three sensors, one for each laser color.  If the reading of these three signals is either below a given reference point (ie too low wattage of laser output) OR their synchronization is incorrect, this error will occur.   Rarely, the polygonal scanner motor could be the problem.  As everyone here seems to have learned, most of the time, the fault is one of the AO driver electronics modules.  If one goes out, then its controlled laser color will not be diffracted into the «PRINT» optical path, the sensor for that laser will see no optical power.  Hence, the proper test for this is to swap the blue and green driver electronics modules, and see if the error now switches to the other laser color.

If the swap produces no change in error, then you are near certain, there is a failure internal to the laser deck.  It could be failure of the actual AO crystal device, internal breakages, optical alignment failures, etc.  But most likely, the individual laser source has failed far below its rated power.  This is the most critical failure and is when we have to replace or rebuild the laser source itself.

  Hello freinds ,3203 machine works well for about 6 hours then brings massage syncronous sensor error
  6073 (no surfix). it makes 1 white print with magenta line in middle. Laser temperature will rise for 5min
  then machine will work for another 1hour this time and prob comes again. Fans are clean and working. All voltages
  on io and laser ctrl pcb are good. I swapped BLUE and Green AOM test print was blue. setup error
  Swaped RED and Green test print gave yellow horizontal lines.

  Hello thanks for reply, i tried to go througth it and checked all voltage levels ok,
  unfortunately i dont have replacement parts pcbs to test, my question is the G add B laser driver interchangeble
  can i swap them

  • Repair Noritsu and Fuji laser AOM drivers, scanners, power suppliers, motor drivers, boards and other electronic equipment for all minilabs in componnent level. Sell AOM drivers and Konica dongles — good price.

  Depends on laser type and driver type. If you have A1 type laser or B1 laser type you can swap them. If you have type Ff laser, than laser drivers is not interchangeable.

  The 6073 error on a 32 series 99% of the time is caused by a failure of the Red AOM driver (signal processor).
  Replace the Red AOM driver and I’m sure the 6073 error will be gone.

  After many test in output check, G showed asynchronous Momentarily though, but
  im concluding to change it . Thanks to all of you.

  Maybe you have more than one AOM driver that is faulty then.
  Because only the RED laser gives the 6073 error message on the 32 series lasers. A fault with the Green and Blue laser AOM drivers will not generate the 6073 error message.

  Synchro sensor error also will be generated if G or B channels are faulty.
  Just after error appeared — you whould enter to OUTPUT check and determine what color will have no synchronization. Also you should look at the frequency (unstable).
  Cause of it may be in defective AOM driver or AOM (crystal).

  B and R are very stable but G showed some unstable behaviour for a few seconds. Any way as Noritsu help
  hinted i have decided to order for complete set of AOM for a start, i will report to you when i replace. Thanks

  Noritsu Help is right, there is only Synchroerror on QSS32-33 machines if the problem is within RED. 90% it’s about AOM Driver in RED channel. However, since about this spring, I am getting QSS32-33 lasers with weak RED laser. Customers reported that they put brand new AOM Driver in RED and… nothing happened. Then I have found that RED laser heads in all those units should be repaired. Curious, but all RED AOMs in the units were also fine, with more than 75% of effectivity, which is perfect for RED.

  My advise to Alfredl is be sure first AOM Driver in red is fine, then run Laser Diagnostic software.

  About Green… If this laser is Type A1, Green should be serviced (IMHO).

  Thanks!

  ok.
  but laser does not generate any errors.
  it means that there is no laser problem with any laser including Green…
  So we have only 2 factors :
  1- dead AOM driver ( you can solve it)
  2- dead AOM crystal of Green laser (only special service required)

  or some kind of distortion on optics axis.

  Hi every one, i appreciate your help, i swapped G and B aom and did another test in output check, R and G were very
  stable and B became unstable this time. Is it right to say that G aom transfered its unstable condition to B chanel?
  Thanks,
  Alferd

  My wide experience in the field of repairing A1 laser units give a clear understanding, that it would be better to service A1 lasers before they give 6105/6106 errors, when not all of the laser heads can be reliably repaired. In opposite, if the electric current already high, but not so high to generate Light Source Status error, all Type A1 laser heads (Blue and Green) can be easily got back to their original parameters. This easy operation can drastically prolong laser head’s lifes, and postpone their dead for years and years. My advice to Type A1 users to consider about this Service if your laser unit is more than 5 years old, pay 50% less than original repair procedure for dead laser units, spend 1 day in service rather a 1-3 weeks, and then work for years again with no headache. (The same about Blue laser head in Ff laser units).

  Thanks!

Probable Cause 1: Faulty AOM driver.
Probable Cause 2: Faulty AOM crystal.
Probable Cause 3: Damaged coaxial cable between AOM driver and AOM crystal.
Probable Cause 4: Damaged cable between Laser control PCB and AOM driver.
Probable Cause 5: Poor contact of synchro-sensor inside the laser unit.
Probable Cause 6: Faulty synchro-sensor inside the laser unit.
Probable Cause 7: Faulty laser module.
Probable Cause 8: Faulty laser driver.
Probable Cause 9: Misplaced AOM Drivers’ BNC connectors.

 In other words:

The sync signal is not received within the specified time period at the sync sensor PCB detector. Over time, the light from the laser diode becomes dimmer: eventually, the laser beam becomes not bright enough for the synchronous sensor to reliably detect it, which causes the 6073 # error message.
The purpose of AOM is to make the laser beam diffract (onto the print) by injecting sound waves of different frequencies. Usually, the blue laser module fails first, then the green one, and then the red one.
If the output sensor does not detect the laser beam, this error will be generated.

To rule out the worst, do the following – determine the cause of this error.

On the qss30 series:
If you have suffix 0001 – you need to check the red AOM (R) driver.
If you have suffix 0002, you need to check the green AOM (G) driver.
If you have suffix 0003 – you need to check the blue AOM  (B) driver.

Replace it with the following AOM driver and run the lab.
If the error code changed, the problem was there.
A more detailed description of the exchange procedure can be found here.

Note 1:
The QSS 31/32/33 series does not have a suffix at the end of the error code.

Note 2:
Only the AOM drivers need to be changed, not the wires!

Note 3:
Sometimes you may have multiple AOM drivers faulty at the same time.

If the error persists, the following suspicious parts are:
– AOM crystal (inside the laser unit). In this case, laser repair will be required.
– Laser input/output of the PCB.
– Laser control board
Also:
– Disconnect and reconnect all connectors to all laser printed circuit boards.
– Check all test points for incorrect voltage.
– Check the quality of all connections of each AOM driver. No result – move on. Double-check if the AOM driver is connected properly.

For example, if an engineer swaps the BNC connector of the blue AOM driver for the green AOM driver, they can spend a lot of time searching for the cause of error 6073. It is recommended that all cables be tagged before replacing them.

– Check the power supply of the laser driver. If the power supply is normal, but the error persists, send us the laser unit.
– Check the quality and condition of the cables mentioned above …

We recommend using the Laser Self-Diagnosis Utility to understand the status of the entire circuit:
AOM driver + AOM crystal + laser module.

You can download it here.
Be sure to download and read the installation guide for this software.

Resume: Laser repair is required (if AOM driver works well)
