| Symptom | Likely Causes (per Manual) | First‑Step Diagnostic | |---------|---------------------------|------------------------| | | • Faulty ink pump on that station. • Clogged nozzle block. • PLC output module failure. | 1. Verify ink pressure (≥ 2 bar). 2. Check LED on pump motor. 3. Use the PLC I/O test from Chapter 3. | | Streaks/white lines | • Worn blanket cylinder surface. • Dirty plate cylinder. • Ink‑film thickness variation. | 1. Inspect blanket surface for abrasion (> 0.15 mm wear). 2. Clean plate cylinder with approved solvent. 3. Run a film‑thickness measurement (micrometer). | | Paper jam at register | • Mis‑adjusted paper tension. • Roller wear or slippage. • Sensor mis‑alignment. | 1. Measure tension (target 12‑15 N). 2. Replace rollers if surface roughness > 0.2 µm. 3. Realign sensor using the sensor calibration routine (HMI → Tools → Sensors). | | UV cure insufficient (soft ink) | • UV lamp power down (age or ballast failure). • Lamp‑to‑paper distance increased (optics shift). • Ink formulation changed. | 1. Measure UV intensity (target 1.5 J/cm²). 2. Verify lamp housing bolts are torqued (8 Nm). 3. Confirm ink spec matches manual’s recommended viscosity. | | Random PLC alarms | • Loose communication cable. • Power fluctuation on the main supply. • Firmware corruption. | 1. Inspect all RJ45/Ethernet connectors. 2. Log mains voltage; should stay within 230 ± 10 V. 3. Reload firmware from USB (see Chapter 3). |
