Read this section if you have a printer problem.

General problems

The lights on the control panel do not come on.

Make sure that the power supply’s DC cable is properly plugged into the printer’s power connector.

Make sure that the power supply’s power cord is properly plugged in the AC inlet of the power supply.

Make sure that the power supply’s power cord is properly plugged into the electrical outlet.

Printing problems

the Paper

If there is no paper jam and the printer has been printing for quite a while, the print head may be overheated. If the print head is overheated, the printer will resume printing when the head has cooled (usually within two

or three minutes).

If there is no paper jam and the print head is not overheated, turn off the printer and turn it back on after about 10 seconds. If the printer still does not work, unplug the power supply cord from the outlet immediately. Then contact a qualified service person.

The ERROR light is off but nothing is printed.

Try to run the self-test to make sure that the printer works properly. See

Self-test later in this section. If the self-test does not work, contact your

dealer for assistance.

If the self-test works properly, check the following:

Check the connection at both ends of the interface cable between the printer and the computer. Make sure that this cable meets the specifications for both the printer and the computer.

Hexadecimal Dumping

This feature allows experienced users to see exactly what data is coming to the printer. This can be useful in finding software problems. When you turn on the hex dump function, the printer prints all commands and other data in hexadecimal format along with a guide section to help you find specific commands.

Starting hexadecimal dumping

Open the printer cover and turn on the power while pressing the PAPER FEED button, then close the cover. The printer first prints “Hexadecimal

Dump” on the paper roll, and prints the data received thereafter in hexadecimal numbers and their corresponding characters.

Notes On Number of Printable Columns

When DIP switch 2-2 is set to ON to increase the number of printable columns, the number of dots and the printable area is as shown below. The

OFF setting is shown for comparison.

Printable Area/Line

c*:)

t*c)

DIP switch 2-2 setting

OFF ON

7 X 9 Font 5 X 9 Font

(*) The 5 X 9 font uses 6 normal dots for one character, but the printer

processes the data as 12 half-dots in the print buffer. Therefore, in this case the printer processes the data as 11 half-dots for one character.

There are restrictions when DIP switch 2-2 is ON, as follows:

1) The printable area for one line is decreased. Setting DIP switch 2-2 to ON increases the number of printable

columns per line but decreases the printable area for one line. Be sure to note the end position of a line and the number of dots for bit-images.

400

385

2) The 10th dot is not printed in the 7 The 7

9 font uses 10 half-dots for one character. However, when

9 font.

DIP switch 2-2 is ON, the printer does not print 10th dot, since the number of printable dots in this setting is 9 and the 10th byte is truncated. Therefore, the 10th dot in some characters is not printed during extended graphic character printing.

This applies to the character for which dots are defined for the 10th byte.

3) The printing results may differ even if the same data is printed. The printer cannot print horizontally adjacent dots. Therefore, the printing results may differ even if the same character codes are transmitted, since the dots placed on the borderline between characters differ depending on the DIP switch

2-2

setting. Particularly in line

drawings, a line may be broken when DIP switch 2-2 is ON.
