After years of development, the laser imagesetter has been fully mature in technology, stable and reliable in performance, diverse in functions, complete in variety and specifications, well-served in place, with a large user base and a large market share. It is difficult in the short term. Was replaced. In addition, the majority of laser phototypesetting machine manufacturers and film manufacturers still recognize the use of film, and more importantly, they are constantly developing laser phototypesetting technology, this article will introduce you to the fault of the laser phototypesetting machine.
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.
In terms of equipment maintenance, computers, servers, printers, plate printers, and supporting uninterruptible power supplies and chillers require maintenance. The maintenance project should be developed into a book, which is divided into days, weeks, half-months, months, quarters, half-years and years. The CTP captain is required to strictly perform and register according to the maintenance schedule items, and the supervisors regularly review, and then the company audit department arranges irregular audits, so that the CTP equipment can be effectively maintained and maintained.

General sewing machines are composed of four parts: head, base, transmission and accessories.
The machine head is the main part of the sewing machine. It is composed of four mechanisms: barbed material, hook thread, thread take-up and feeding mechanism, and auxiliary mechanisms such as thread winding, material pressing, and tooth-dropping.
The base is divided into two forms: platen and chassis. The platen of the table-type machine base plays the role of supporting the machine head and is used as a workbench during sewing operations. There are many styles of tabletops, such as one-bucket or multi-bucket folding Tibetan type, cabinet type, writing table and so on. The chassis of the chassis-type machine base plays the role of supporting and storing the machine head, making the sewing machine easy to carry and store.
The transmission part of the sewing machine is composed of parts such as a frame, a hand crank or a motor. The frame is the backbone of the machine, supporting the deck and footrests. When in use, the operator steps on the pedal, drives the rotation of the pulley through the crank, and drives the head to rotate through the belt. Most hand cranks or motors are directly mounted on the nose.
Accessories for sewing machines include needles, bobbins, screwdrivers, oilers, etc.
