During the process of adjusting focus of green laser pointer
The screen prompts the 21-119 internal hardware failure. Film picked up the film on error ". Analysis we observed. Ministry of Machinery spaces of the camera picked up piece and suction cups. No deformation and damage. When we replace a box of new film after the test machine. Camera printing to return to normal. Therefore, we determine the fault may be the piece the box itself. Repair the chip box will be failure to get the darkroom. Opened the first of three film crease. And uneven. Come up with a damaged film, and then this box of film test machine. The camera is back to normal. Camera software system failure. Phenomenon after loading the film, the camera does not print. The screen display system has been "ready". But the camera without any action of the transfer film. Shutdown and then start the laser camera.
P601 to P606 print error camera system failure but not for printing. Note: P followed by the encoding. P621 print error system undetectable film parameter file. Call the service department of my company. P622 print error camera system failure but not for printing. By the Local Panel to conduct a calibration print operation. P623 print error due to system failure can not perform the print operation, call our service department. Note: P followed by the encoding. P624 calibrate fail print density failure to perform a printing operation. Replace the cassette. This failure occurs, the user can not use the manual mode (mostly due to the film in the cassette case of thermal aging). The warning label of green laser pointer should contain the necessary information.The laser energy of green laser pointer will be in just a little spot
This value is beyond the scope of the 2500-4000 allowable range. According to the analysis of the above consideration is that the prism dirty. Disassemble laser module, a minor with a cotton swab dampened with water to carefully wipe each prism. Replace the rear, the Power On Self Test and found that this value becomes 3100, the self-test passed. And print out the film compared to contrast more clearly than before. Maintenance process of the whole machine this point. Through theoretical analysis and practical tests to solve the problem, but also gain some maintenance tips. Kodak DryView 8700 laser camera does not exposure to the Troubleshooting of laser camera does not exposure fault repair Fault phenomenon: boot laser camera initialization self-test completed at the same time the instrument alarm signal can not normally work.
