Hexadecimal Dump  
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.  
To use the hex dump feature, follow these steps:  
1. After you make sure that the printer is off, open the cover.  
2. Hold down the REVERSE button while you turn on the printer.  
3. Close the cover.  
4. Run any software program that sends data to the printer. The  
printer prints “Hexadecimal Dump” and then all the codes it  
receives in a two-column format. The first column contains the  
hexadecimal codes and the second column gives the ASCII  
characters that correspond to the codes.  
Hexadecimal Dump

A period (.) is printed for each code that has no ASCII  
equivalent.  
During the hex dump all commands except DLE EOT and  
DLE ENQ are disabled.  
5. Open the cover to set the printer off line so that it will print the  
last line.  
6. Close the cover and turn off the printer or reset it to turn off the  
hex dump mode.

Notes on slip paper  
The slip paper must be flat, without curls or wrinkles,  
especially at the top edges. Otherwise, the paper may rub  
against the ribbon and become dirty.  
There must be no glue on the bottom edge. Choose slip paper  
carefully since paper feeding and insertion are affected by  
gluing conditions (such as glue quality, method, and length)  
and glue location (see the illustration below). Be especially  
careful when slip paper is wide and has glue on the left edge,  
since it may not feed in a straight line.

Since the BOF sensor uses a photo sensor, do not use paper that  
has holes at the sensor position, or is translucent.  
Since the TOF sensor uses a reflective photo sensor and it  
detects from the back of slip paper, do not use paper that has  
holes or dark portions with low reflection (less than 40%  
reflection) at the sensor position.
