Caution:
Do not turn off the printer while it is printing. Always press the
Pause button to stop printing and then turn off the printer.
❑
If the self test results are satisfactory, this means that the
printer itself is all right and that the problem probably lies
in the printer software settings, application settings, the
interface cable (be sure to use a shielded cable), or the
computer itself.
❑
If the self test does not print satisfactorily, this tells you there
is a problem with the printer, such as an empty ink cartridge
or dirty print head. See “Problems and Solutions” on the next
page for possible causes and answers to the problem, or go
directly to “Cleaning the Print Heads” on page 10-36.
Hex dump mode
Experienced users can use the hex dump mode to pinpoint
communication problems between the printer and a software
program. To enter the hex dump mode, follow these steps.
1. Make sure the printer is turned off and paper is loaded in the
sheet feeder.
c
Caution:
Use paper at least 210 mm (8.27 inches) wide, for
example, A4 size paper loaded short edge first. Otherwise,
the print head will spray ink directly onto the platen,
which could mar future printouts.
2. Hold down the LF/FF and Load/Eject buttons and press
the
Operate button to turn on the printer.
3. Send data from the computer.
The printer prints the exact code it receives from the computer
in hexadecimal format.
