Chapter 4 Problems and Solutions
4.1 Problems and Solutions
Most problems you may encounter while operating your printer have simple solutions.
You can check the operation of your printer using the self test. See “Running the Self Test” on
page 1.6. If the self test works properly, the problem probably lies in the computer, the software, or
the interface cable. If the self test does not work, contact your dealer or qualified service person
for assistance.
Note: If you are an experienced user or a programmer, you can print a hexadecimal dump to
isolate communication problems between the printer and computer. To print a hex dump,
turn off the printer. Next, hold down the LF/FF and TEAR buttons while you turn on the
printer. Then send data from your computer. The printer prints all the codes it receives in
hexadecimal format.
4.2 Power Supply
Power is not being supplied normally.
Phenomenon 1: The lights on the control panel do not go on.
Solutions:
1. Check that the power cord is properly plugged into the electrical outlet.
2. If the electrical outlet is controlled by an outside switch or automatic timer, use another outlet.
3. Plug another electrical device, such as a lamp, into the outlet to determine whether the outlet is
operating properly.
Phenomenon 2: The lights come on briefly and then go off. The lights stay off even when
the power is turned on again.
Solutions:
Check whether the printer’s rating volage is matched with the power cord. If not,
unplug the power cord immediately and contact your dealer or a specified jolimark
service center for advice. Do not plug the power cord to the electrical outlet again.

the driver’s printer settings.

computer specifications.

The printer may be out of paper. Load paper in the printer.
