In daily production on Komori series presses, delivery section faults are among the most common issues encountered by press operators and maintenance personnel. This Japanese-made model is known for its stability, with mature H-UV drying and automatic registration systems, and even ink distribution across the ink train. If not addressed promptly, the consequences can range from compromised registration accuracy and print quality to extended downtime in severe cases.
1. Fault Symptoms: Inconsistent stacking, sheets dropping, skewed pile on the delivery table, and back-side marking caused by uneven powder spraying.
2. Cause Analysis: Timing deviation in the delivery chain and gripper opening/closing sequence; improper powder quantity or clogged spray nozzles; incorrect adjustment of the jogger mechanism; failure of the braking roller/suction wheel. Given that Komori Japanese presses are renowned for stability, with mature H-UV drying and automatic registration systems and even ink distribution, troubleshooting should prioritize checking key components against standard parameters.
3. Maintenance Guide: Correct the delivery gripper opening/closing timing and chain phase; clean spray nozzles and set powder quantity according to paper weight; adjust the front and side jogger plates; inspect the suction wheel and braking roller.
4. Daily Maintenance: Regularly clean the powder spray system; check delivery chain lubrication; set delivery parameters according to paper type.
The above methods also apply to models such as LS440, LS629, Lithrone, GL840, and G40. For practical operation, refer to the PQC Print Quality Control System / KMS console and site conditions. For complex situations, it is recommended to contact professional maintenance support via the printm.cn platform.
