DOVER FLEXO Product Lines We Repair
Our engineers are trained on the full DOVER FLEXO product range. Below are the major product families we service.
Flexographic Press Control Systems
Integrated servo and stepper motor control modules for flexographic print presses, managing color registration, web tension, and impression control. Common issues include servo loop instability, encoder feedback loss, and press synchronization faults affecting print quality.
Ink Jet Printing Modules
Digital ink jet head drivers and valve control electronics for variable data printing on narrow-web substrates. Typical failures include nozzle driver burnout, ink pressure sensor malfunction, and firmware corruption on printing control cards.
Servo Drive and Motor Control
High-precision servo amplifiers and AC brushless motor controllers for print head registration and web drive motors. Repair focuses on gate driver shorts, resolver module faults, and current sensing circuit failures common in narrow-web applications.
Encoder and Sensor Modules
Rotary and linear encoder modules, color mark detection sensors, and web edge guidance electronics. Common faults include magnetic sensor drift, TTL output loss, and harness connection issues affecting print registration accuracy.
PLC and HMI Terminals
Allen-Bradley and custom PLC controllers paired with Dover-branded operator interface terminals for press setup, job recipe management, and real-time monitoring. Typical failures include display panel dead pixels, communication card faults, and program memory corruption.
Power Supply and Conditioning Modules
24VDC regulated supplies, multi-output industrial power modules, and harmonic filtering units for sensitive servo and control electronics. Common issues include bulk capacitor failure, transformer secondary faults, and output short-circuit protection tripping.

Common DOVER FLEXO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DOVER FLEXO equipment arriving at our workshop.
- ✓Servo loop instability causing registration drift — Encoder feedback intermittently loses signal or resolver module develops magnetic hysteresis, causing the servo amplifier to lose position reference and trigger oscillation in the print head carriage.
- ✓Ink jet nozzle driver short circuit — High-voltage piezo driver circuits experience dielectric breakdown under thermal stress or ink moisture ingress, causing gate driver MOSFET shorts and loss of individual nozzle control.
- ✓Color mark sensor false detections — Optical sensor lens contamination, LED aging, or comparator circuit drift causes erratic color mark recognition, leading to incorrect registration and variable position errors on each press cycle.
- ✓PLC communication card timeouts — Ethernet or serial interface transformer failure, connector corrosion, or firmware synchronization loss disrupts real-time data exchange between the PLC and HMI terminal, causing intermittent press stops.
- ✓Power supply output sag under servo load — Bulk capacitor ESR degradation or transformer secondary wire fracture causes output voltage to sag during heavy servo current draw, triggering brownout resets and servo fault codes.
- ✓HMI display touch panel unresponsiveness — Resistive or capacitive touch overlay develops open circuits from mechanical stress, moisture ingress, or calibration data corruption in the terminal's non-volatile memory.

Frequently Asked Questions — DOVER FLEXO Repairs
Do you repair Dover Flexo equipment anywhere in India?+
Yes. Synchronics repairs the full Dover Flexo product range including flexographic press control systems, servo drives, ink jet printing modules, PLC controllers, and HMI terminals. We offer PAN-India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Kolkata, and all other major cities. All repairs are performed in our Vadodara facility by certified technicians with 20+ years' experience in narrow-web printing electronics.
How do you diagnose registration and color mark sensor faults on Dover Flexo presses?+
Synchronics uses calibrated encoder simulation units and optical test patterns to isolate sensor and servo feedback problems. We measure sensor output voltage under light and dark conditions, verify encoder TTL pulse timing and frequency, and perform closed-loop registration tests at multiple press speeds. Our diagnostics match Dover Flexo factory test protocols, identifying whether the fault is sensor hardware, amplifier circuitry, or PLC configuration.
What is your turnaround time for Dover Flexo servo drive and ink jet controller repair?+
Standard turnaround for servo amplifiers and ink jet driver boards is 7-10 business days including component testing, repair, and functional verification. Urgent repairs can be expedited to 3-5 days with priority handling. For critical press downtime situations, we maintain loaner servo and driver modules to minimize customer production loss while your original equipment is being repaired.
Do you stock spare parts for Dover Flexo servo drives and encoder modules?+
Yes. Synchronics maintains inventory of high-failure-rate components including servo gate driver modules, encoder magnetic pick-up heads, power supply capacitors, and servo amplifier output stages. We also source Dover Flexo original spare parts through authorized channels for customers requiring OEM components. Quick-stock ordering is available for common replacement modules with 2-3 day delivery across India.
Can you repair Dover Flexo press controller PLCs and HMI terminals?+
Yes. Synchronics repairs Allen-Bradley CompactLogix and ControlLogix PLCs used in Dover Flexo systems, as well as Dover-branded HMI operator terminals. We recover corrupted program files using industrial EEPROM readers, replace failed communication cards, repair touch panel overlays, and reprogram backup firmware. We also test reprogrammed controllers against your original job recipes to ensure press operation is restored exactly as configured.
How do I send my DOVER FLEXO unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DOVER FLEXO drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DOVER FLEXO repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DOVER FLEXO unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
