Question	Answer
What does it mean when the status indicator light is showing red?	The red light shows the printer is in an error state. The printer cannot print until the error is cleared. Possible causes of a red light showing are as follows: The printer is out of labels or the printer is out of ribbon ( TLP models only ) The printhead is open, not latched down all the way. Press down on the top cover of the printer to see if the error light clears and goes to green. The ribbon spool is slipping on the ribbon spool holder on TLP models: More information The ribbon may not be installed correctly - the ribbon core has two notches in the end of it, these must be fitted into grooves in the printer. If the ribbon is not installed correctly the ribbon will slip and cause the printer to error.
What do I do if I have poor print quality?	Some causes of poor print quality are; dirty print heads, label and ribbon combinations or the print speed. Dirty print heads can result in poor heat transfer and a poorly printed image. The types of labels and ribbon (TLP only) can effect the quality of print if this is the fault your supplier will need to be contacted. Slowing down the print speed can help if the print is too light. It is important to run tests for your application to choose the optimal setting.
How do I clean dirty or blocked label sensors?	It is very important to keep the label sensors clean and free of debris in order for the printer to calibrate properly. When sensors are dirty or blocked it may cause the printer to print ' gap not detected ' onto the label. Using Isopropyl Alcohol and a cotton swab the lower gap/mark and upper gap sensors can be cleaned.
What do I do if the printer fails to detect ribbon out? (TLP only)	If the mode of the printer is set to direct thermal ( D ) the printer will not detect a ribbon out. This can be corrected by setting the printer to thermal transfer by sending the EPL O command. The mode can be viewed on the configuration label under Option. For further assistance view Configuration label details.
What do I do when the printer firmware becomes corrupt?	Firmware needs to be downloaded to the printer, download the firmware downloader and firmware for your printer below.
What do i need to know when using a Keyboard Display unit (KDU)?	When using a KDU it is important for the printer communication settings to be set to 9600 Baud, No Parity, 8 data bits, 1 stop bit. If it is set otherwise then the KDU will lock up. Make sure EPL format is written correctly in order for the KDU to respond. For further assistance view KDU setup and troubleshooting details.
