Chapter 8: Troubleshooting

...individual dots of the print-out are missing?
The print head may be damaged. Contact your supplier.
...the print-out appears faint?
Replace the ribbon cassette with a new one as described in Chapter
6 and adjust the paper thickness correctly. If there is no marked
improvement in the printing, contact your supplier.
...text processing files are printed differently to the settings de-
fined in the printer menu or operator panel?
Many application programs send control commands to the printer
at the start of and during data transmission. This »initialisation
string« contains control characters and commands that set up the
printer for the subsequent print job. These commands have priority
over the settings selected via the operator panel or menu. Check in
the associated manual whether you can alter the initialisation
string. If this is the case, delete the unwanted commands.
...the menu and print function buttons are inoperative?
The function of the buttons can be deactivated by means of the
menu item Operator Panel Functions of the printer menu. If the
printer is part of a network or is shared by several people, the re-
spective system administrator has probably used this option to pre-
vent the printer settings being altered indiscriminately. Hold down
the MENU button when switching on to be able to alter this item.
...if I wish to check the data sent by the computer to the printer?
Use the hex dump mode. To activate this mode, hold down the FF/
LOAD button and the SEL button when switching on the printer.
All data sent to the printer including text and printer commands
will then be printed in hexadecimal form and ASCII format. When
you wish to return to normal print mode, switch the printer off an
then on again.
