How to fix a handheld inkjet printer that won't print text
I. Data Transmission Failure
Symptom: Failure to transmit data with devices such as computers.
Causes and Solutions:
USB Cable Connection Issues: Incorrect or loose connections can cause communication problems. Ensure the cable is properly connected. If the screen does not confirm the connection, unplug and reconnect the cable securely.
Software and Driver Issues: Faulty installation or malfunction of the inkjet software or USB driver may disrupt transmission. Verify the installation status. If issues occur, uninstall the software and reinstall the correct version from official sources.
II. No Characters Printed
Symptom: Unable to print characters normally during operation.
Causes and Solutions:
Encoder Coil Issues: Loose or detached encoder coils disrupt print position and movement control. Inspect, reattach, and secure them.
Ink Cartridge Issues: Depleted ink prevents ink supply. Check the cartridge and replace it if empty.
Data Issues: Missing valid printing data. Verify data availability and reload correct data through proper channels.
Ink Cartridge Contact Issue: Poor contact between cartridge and device. Remove the cartridge, wait briefly, then reinsert securely to restore ink flow.
