If your receipts are barely legible, don't worry—this is an easy fix. Every Clover printer is a thermal printer, except for their Kitchen Printers. This means they do not use ink to print. If your Clover printer is printing receipts with light characters or without characters, please make sure to utilize the following steps to troubleshoot your device: 1. Supply the correct thermal-compatible paper to the printer. 2. Make sure the thermal paper roll is loaded into the printer correctly. 3. Clean your device’s printer head of any dust or debris. 4. Be sure your device has a sufficient power supply and is plugged in correctly. 5. Check your printer settings to diagnose your print density.
