Why Preventive Maintenance Matters for Print Houses

In high-volume industrial offset and web printing, machine downtime is the single greatest threat to profitability. When a press running at 45,000 newspaper copies per hour suffers a sudden cylinder jam or PLC communication fault, publication schedules break and paper waste climbs. Most of these catastrophic failures are preventable through systematic daily, weekly, and monthly audits.

At Electro Soft BD, our field engineering experience across major Dhaka newspaper presses has shown that clean wiring terminals, checked bearing vibrations, and proper cylinder lubrication reduce emergency calls by over 70%.

A dollar spent on replacing a worn gripper pad or a failing line capacitor saves ten dollars in paper waste and lost printing time.

The 3-Step Press Audit Checklist

Implement these schedules in your press room to protect your machinery assets:

1. Daily Checks (Before Shift Startup)

• Inspect dampening system pH and conductivity levels to maintain perfect water-ink balance.
• Scan logic controller PLC LEDs for signal faults or bus connection warning indicators.
• Clean photoelectric register sensors to prevent registration timing errors.

2. Weekly Checks (Scheduled Downtime)

• Lubricate cylinder gripper shafts and paper feeder cams to prevent sheet-slippage wear.
• Clean ink fountains and inspect ink duct key motors for mechanical drag.
• Audit pneumatic valves and compressed air line filters for water build-up.

3. Monthly Checks (Technical Shutdown)

• Perform thermal imaging scans of drive cabinets to check for loose contactors.
• Measure cylinder parallel alignments and verify gear-lash tolerances.
• Retrieve and save electronic backups of PLC systems and drive parameters.
