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.
