Problem
Printout darkness is
uneven across media path.
Printout is not in desired
position.
Use Dumpmode to verify that the printer is receiving data from
the host correctly.
In Dumpmode, the printer runs a Fingerprint program called
Line Analyzer. As the name implies, the Line Analyzer captures
incoming characters on the communication ports and prints
them on one or more labels. Line Analyzer uses "autohunt" which
means the program scans all applicable ports for data.
The easiest way to enter Dumpmode is through Testmode or
Extended Testmode (see
Testmode" on page 34)
When Dumpmode has been entered, the Printer will tell you this
by printing "DumpMode entered" on a label. The display shows
the Dumpmode icon, and the printer is ready to receive data.

• Check if platen roller needs cleaning or
replacement.
