Troubleshooting
Alert: Ribbon In (ZD420 Cartridge Printer only)
A print command has been sent to the printer and it is in Direct Thermal Mode with Ribbon
installed.
Note • The printer has two different heat settings - one for Direct Thermal and one for
Thermal Transfer. They are designed to have equivalent print density/darkness at the
same setting level.
Possible Cause - 1
There is a Ribbon Cartridge in the printer while the printer is set to Direct Thermal Mode
(and printing on direct thermal media).
Resolution
Remove the ribbon cartridge from the printer without turning the printer OFF. Close the
printer. You may need to press the FEED button once or the PAUSE button the get the
printer to resume your print operation.
Possible Cause - 2
The printer is incorrectly set to Direct Thermal Mode when you are trying to print using
Transfer Media and Ribbon Cartridge to print.
Resolution
Change the PRINT METHOD to THERMAL TRANS (Thermal Transfer) mode. The print
format/form send for this print job may have Direct Thermal mode set with a ^MTD set
instead of ^MTT. See the ZPL Programmer’s Manual for details on printer programming.
For printer links to manuals, see the About section of this guide.
To change this setting on the dynamically:
• Use the printer’s LCD user interface (if present) to change the setting. See PRINT
METHOD in Printer Configuration Menus chapter.
• Use an Ethernet (LAN or WLAN) printer’s Print Server Web page to access and
set the PRINT METHOD to THERMAL TRANS (Thermal Transfer) mode. See
PRINT METHOD in Printer Configuration Menus chapter for navigating the print
server users interface.
