Maintenance Features
The service manual provides detailed instructions for disassembling and assembling the printer, which are crucial for maintenance and troubleshooting. Key maintenance aspects include:
General Cautions:
- Do not disassemble components or loosen screws while the printer is working.
- Carefully check connectors for damage during disassembly.
- Prevent static electricity when handling the print head or other electronic components.
- Ensure a minimum 20-second interval between powering off and on the printer.
- Avoid printing without paper to prevent damage to the platen and print head.
- To extend print head life, set a low printing concentration if the print effect meets requirements.
Disassembly and Assembly:
The manual provides step-by-step instructions for disassembling major components:
- Lower Shell Unit: Involves removing four screws from the bottom and disconnecting cables from two interfaces.
- Cutter Cover, Top Cover & Main Holder: Requires removing cover shafts and torsion springs in the open cover state.
- Main Board: Involves unplugging all cables and removing four screws.
- Gear & Motor: Requires removing screws from the gear cover plate and the motor.
- TPH (Thermal Print Head): Involves removing two nuts from the TPH shaft to separate the shaft, button bar, and pick, then removing the TPH upward.
- Cover Opening Button, Springs & Head-up Sensor Switch: Involves pressing the cover opening button to separate it and the spring from the main holder, and removing the screw of the head-up sensor switch.
Assembly is performed in the reverse order of disassembly. Specific notes for assembly include:
- Aligning the paper container unit with the corresponding slot of the lower cover (taking photos as reference is recommended).
- Ensuring the top cover open angle is less than the maximum during paper container assembly.
- Verifying normal opening and closing of the top cover after assembly.
Troubleshooting:
The manual offers solutions for common printer issues:
- Printer Not Working (LED off): Check power supply connection, replace AC/DC adapter, turn on the printer, or contact the dealer if the circuit board is damaged.
- LED Indicator and Beeper Alarm:
- Error LED and paper LED always on with beeper alarms: Close printer cover (if open), reload roll paper (if paper end), or turn off and resume printer when print head cools (if overheated).
- Error LED blinks with beeper alarms: Print with specified voltage (for over-voltage/low-voltage) or restart printer (for cutter jam).
- Troubles During Printing:
- Blurred printing or spot: Check paper loading, use recommended paper, clean print head/roller, or increase print density.
- Paper not feeding normally: Open cover, check paper path, remove jammed paper.
- Vertical print words missing: Clean print head/roller, or contact dealer if print head is damaged.
- Problems During Paper Cutting:
- Cutter abrasion/insufficient cutting: Replace the cutter.
- Cutter jam (movable cutter stuck): Replace worm gear/wheel (if abrasion), replace motor (if burnt), or clean paper scraps on transmission system.
- Thermal printer head overheated: Reduce printing density.
- Driving too fast: Reduce printer speed.
- Wrong paper feeding position: Put paper parallel with mount and insert correctly between platen roller and print head.
Cutter Jam Troubleshooting:
Specific steps are provided for cutter jams:
- Do not press the cover open button to avoid blade damage.
- Fix the printer with one hand and press the convex bars on either side with the other hand to push up and open the front cover.
- Rotate the gear until the blade returns to its normal position.
Auxiliary Materials and Tools:
- Maintenance Tools: Cross screwdriver, normal screwdriver, cutting pliers.
- Auxiliary Materials: Lubricating grease, alcohol, rayon balls.
The manual also includes an exploded drawing and a comprehensive list of printer components with their descriptions, quantities, and remarks for easy identification during maintenance.
