Thermal Receipt Printer Not Printing Clearly? Quick Fix Guide

Billing counters, retail shops aur restaurants me thermal printers ka smooth chalna behad zaroori hai. Achanak light print aana ya beech me text miss hona ek common fault hai.

Common Causes Aur Instant Fixes:

1. Ganda Thermal Printhead: Thermal paper ki chemical residue printhead line par jam jati hai. Printer turn-off karein aur 99% IPA (Isopropyl Alcohol) swab se head gently wipe karein.
2. Platen Roller Wear: Rubber roller par dhool aane se paper ka grip loose ho jata hai, jisse heat transfer uneven hota hai.
3. Power Adapter Drop: Agar 24V adapter proper output nahi de raha, toh heating elements poori tarah heat generate nahi kar paate.

Cleaning ke baad bhi agar receipt me vertical blank gap aaye, toh iska matlab head ke micro-dots burn ho chuke hain aur naya Thermal Printhead install karna hoga.
