9 Are you using a printer selection switch or a printer
buffer?
With bi-directional interfaces, operation is some-
times unreliable when using printer switching
boxes or printer buffers. If you are using a printer
selection switching box or printer buffer, use one-
way communication.
10 Is your cable too long?
Do not use a cable that is longer than you need.
The signals become more unstable as the cable
gets longer.
11 Are you using the wrong ink cartridges?
Use only the recommended ink cartridges. Do not
use ink cartridges from other manufacturers.
12 Are the ink cartridges correctly installed?
Insert ink cartridges in the carriage with the iden-
tification markings (B side) face up. This applies
to all ink cartridges except the reversible types :
Econo Black and Finish II.
13 Is the ribbon on an ink cartridges used up?
When the ribbon in an ink cartridge has been
used up, black and silver stripes will be visible on
the ribbon. When these appear install a new ink
cartridge. After replacing the ink cartridge, print-
ing will continue from where it left off.
14 Do you have enough hard disk space?
The DP-5000 requires work space on the hard
disk when it prints. Keep enough space open on
the disk for the printer to operate (after printing,
the work space is released.)
15 Does the hard disk have areas where reading or
writing are unreliable?
If there are areas on the hard disk where reading
or writing are unreliable, sometimes a printing
error will occur and printing will stop. Periodi-
cally use a utility like SCANDISK that comes
with MS-DOS 6.0 (or later) or Windows 95/98 to
prevent these problems.
Printing is light, distorted, or has gaps
1 Has one of ribbons separated from the head?
Stop the printing and reinstall all the ink car-
tridges. Take up any slack in the ribbons. If a par-
ticular ink cartridge repeatedly causes problems,
try a different ink cartridge.
