RW 420 User Guide

To print out a listing of the printer’s current configuration fol-

low these steps:

1. Turn the printer off.  Load the media compartment with 

journal media (media with no black bars printed on the 
back)

2. Press and hold the Feed Button.
3. Press and release the Power button and keep the Feed 

button pressed.  When printing starts, release the Feed 
button. 

  Refer to Figures 23 through 23b for a sample configura-

tion printout.

It the printer has locked up and is not responding to any op-

erator inputs or external commands, from either a connected 
terminal or a linked LAN, you can perform a forced shutdown.

  • If the printer software locks up during normal operation, 

force the printer to shut down by pressing and holding 
the Power Button for 3 seconds.

  • If you try to turn the printer off normally and the soft-

ware locks up, the printer will automatically shut itself off 
after a 10 second delay.

  • If you try to turn the printer off and it does not respond, 

you can force an immediate shut down by pressing and 
holding the Power Button again within 10 seconds.

A forced shutdown will preserve the printer’s data and set-

tings

If there’s a problem transferring data between the computer 

and the printer, try putting the printer in the Communications 
Diagnostics Mode (also referred to as the “DUMP” mode). The 
printer will print the ASCII characters and their and their text 
representation (or the period ‘.’, if not a printable character) for 
any data received from the host computer 

To enter Communications Diagnostics Mode:

1. Print a configuration label as described above. 
2. At the end of 2nd diagnostics report, the printer will print: 

“Press FEED key to enter DUMP mode.”
