Extended Diagnostics
Extended diagnostics are entered after Level 0 diagnostics, are part of the firmware, and are activated in one of two
ways. The first is by holding
button and/or button and applying power (Power On).
The second is by holding button and/or button and activating the * Button from OFF or
Soft Power On.

Self-Test Diagnostics
Self-test mode allows the printer to be tested to assure that it is working correctly. A number of tests may be run.
Self-test is entered by holding the
button during initial power on.
Hex-dump Mode
To enter hex-dump mode, press and hold the button when resuming operation from OFF mode. Enter OFF by
pressing and releasing the * Button. Press and hold the button while pressing and releasing the * Button. Be
sure to release the button as soon as the carriage starts to move to prevent paper feeds.
Hex-dump mode is used to diagnose communication problems with the printer. As information is received by the
printer, the information is converted to a Hex/ASCII format and printed. No translation is made, which means no
commands are interpreted. All information is converted to Hex/ASCII and printed on the receipt. If a carriage
return is sent to the printer, it is translated to 0D in the hexadecimal field and "." in the ASCII field.
The format follows.
54 68 69 73 20 69 73 20 This is
61 20 74 65 73 74 0D 0A a test..
Several indications of printer and host communication problems can be deduced from hex dump mode. If the printer
is printing all 3F "?" symbols, the parity or the number of bits is wrong. If the printer is printing some Hex 3F "?"
signs when it should be printing other characters, either the parity, baud rate, or bit length setting is wrong. If the
printer prints incorrect characters (like Hex C1 instead of Hex 41 "A"), it is set for 8-bit data, and the host is set for
7-bit. In most cases, the print problem can be traced to the host and printer being configured differently.
