Can a Nearly 20-Year-Old KODAK ThermoFlex / ThermoFlex II CTP Return to Production After Laser Aging?

KODAK ThermoFlex / ThermoFlex II laser repair helps classic equipment continue to deliver value.

The machine still runs, but plate making is getting slower. Production jobs are queued, and the laser system suddenly reports an error and stops.

For a KODAK ThermoFlex / ThermoFlex II flexo CTP used for nearly 20 years, laser aging ultimately affects the two things the shop cares about most: production efficiency and delivery time.

Does equipment in service for nearly 20 years have to be replaced? If the mechanics, control system, and overall condition are still good, professional repair of the laser system is worth evaluating first.

Problem Summary

A nearly 20-year-old KODAK ThermoFlex / ThermoFlex II flexo CTP was still running, but plate making was becoming slower and production was less stable. Jobs were waiting, and the laser system eventually faulted and stopped the machine. The key question was whether the laser system could be repaired so the machine could return to production.

The source attributes the issue to laser aging in a long-serving machine. The practical test is not only whether the machine powers on, but whether it can return to stable, deliverable production.

Field Symptoms

• The machine still runs, but plate making becomes slower.
• Production jobs are waiting.
• The laser system reports an error and stops.
• For a long-used KODAK flexo CTP, laser aging affects production efficiency and delivery time.

Error Meaning: Why a 60-Beam Laser System Becomes Unstable

This laser system uses a 60-beam configuration, and the laser unit has a special shape. After long-term use, multiple beams may age to different degrees.

When the output status of each beam gradually diverges, the equipment may show lower plate-making efficiency, unstable operation, or even downtime.

For this type of repair, the completion standard cannot be simply “the laser emits light again.” What affects real use is whether the repaired laser can meet the original machine’s imaging and operation requirements.

Diagnostic Path: Inspect Aging Status Before Choosing How to Repair

Multi-beam aging is often uneven. Which channels are clearly degraded, which need adjustment, and which still have normal usable value must be determined one by one through inspection. The exact condition of each beam had to be confirmed by testing, not assumed.

We use dedicated repair technology to treat the laser unit in a targeted way, then adjust it based on inspection results. The goal is to restore the laser performance required by the original machine.

The value of repair is not only getting the machine to start again; it is enabling it to take on stable production tasks again.

What Was Checked On Site

Laser repair effectiveness must be judged by actual inspection results.

Before and after repair, the same test conditions are used to determine whether each beam’s status has improved, whether output meets requirements, and whether it remains stable after adjustment.

From inspection to on-machine testing, verification should land in actual production: whether the device can complete imaging normally, whether plate-making efficiency has recovered, and whether continuous operation is stable.

Restoring original machine performance requires inspection evidence and must stand up to on-machine validation.

Final Result: Before-and-After Comparison and On-Machine Verification

The result of laser repair is shown through before-and-after inspection. The repaired laser status is presented at the same display scale as before repair for direct comparison.

A direct command test after repair provides further inspection evidence.

The practical result is measured on the machine: normal imaging, recovered plate-making efficiency, and stable continuous operation.

Repair Action: Targeted Laser Repair and Automatic Adjustment

With 60 beams, checking each channel and repeatedly adjusting them is a time-consuming part of repair.

We specifically use laser automatic adjustment technology to assist with multi-beam adjustment, reducing repeated manual operations and making the repair process simpler and more efficient.

Combining inspection and adjustment also helps engineers understand the status of each laser more clearly and provides a basis for verification after repair.

Keeping classic equipment in stable use depends on repair technology, adjustment methods, and actual verification working together.

Engineering Lesson: Do Not Retire the Whole Machine Too Quickly

For a KODAK ThermoFlex / ThermoFlex II that still has production value, first determine the fault scope, then compare the investment in repair versus equipment replacement before making a suitable decision.

If your equipment is showing any of the following:

• Plate-making speed drops, affecting delivery.
• Multiple laser beams age, with inconsistent output.
• The laser system faults and the device stops.
• You want to evaluate laser repair to extend the equipment’s service value.
