2.Printing Problems
Nothing can be printed with ERROR LED ON – Check the Paper Out LED. If it is ON, most probably the paper roll is not installed or is at or near the end. Install a new paper roll. If the Paper Out LED is OFF, please check for paper jam described in next item.
If there is no paper jam and the printer has been printing for quite a period of time, the print head may be overheated. It will usually cool back in few minutes and the printing will resume.
If there is no paper jam and the print head is not overheated, turn off the printer and wait for half a minute then turn it back on. If the problem still remains, contact a qualified service person.
Nothing can be printed with ERROR LED OFF – Try to run self test according to previous chapter to check if the printer itself works properly. If the self test passes, check the following:
a. Check the connection of the interface cable at both the printer and computer ends. Also make sure that this cable meets the specification required for both the printer and the computer and also the settings by software.
b. Check the printer data communication settings against the computer. The printer settings can be found easily on the self test print out.
If the problem remains or the self test fails, contact your dealer or a qualified service person.
Poor printing quality – Contaminants like paper scraps and dusts on the print head or near worn out inked ribbon can lower the print quality drastically. Clean the print head replace the ribbon cassette as required.
