If a large-scale mechanical equipment such as the photo-setting machine is not well-maintained during use, it will inevitably have some faults. Today, I will share some common faults and solutions for the photo-aligning machine. This article will introduce you to the laser imagesetter.
The inspection was carried out in comparison with the row machine, but no obvious failure was found. Remove the upper cover of the cassette, open the photo-setting machine, and let the film enter the film manually. On the other hand, the hand-held motor of the photo-aligning machine automatically turns the wheel and finds that it is rotating, but the friction wheel of the collecting box The speed of rotation is slower. After shutting down, use your finger to move the wheel against the motorized wheel of the machine, and then add some resistance to the friction wheel of the box, and find that it does not rotate.
After careful observation, we can guess that this reason is caused by the long-term friction caused by the rotating wheel of the take-up motor and the friction wheel of the take-up box, which causes the rubber to age and wear, resulting in poor contact between the two rubber wheels. Generally, it can be adjusted by comparing the film collection with the elastic scale of the steel shrapnel on the back of the motor to solve the fault, but we found that at this time, the elastic scale has been adjusted to the maximum extent. Therefore, it is only necessary to consider the shrinking wheel on the take-up motor and the take-up box to eliminate the malfunction.
Although CTP and digital printing systems have entered the sales market and have a certain impact on the entire industry, it is far from the expected results. At present, there is no strong market demand in China, most CTP systems or digital printing machines. It is only installed in large-scale printing enterprises for self-use, and does not form a good market network, which has little impact on the laser phototypesetting market.
