• The rubbery smooth surface has become polished and slippery,

There are long tracks of missing print (blank vertical lines) on

several labels.

• The printhead is dirty. Clean the printhead.

• The printhead elements are damaged.

The printing does not start at the top of the receipt or misprinting of

one to three receipts.

• The printer needs to be calibrated. Refer to the two-flash sequence of Feed Button Modes

on page 31 in this section.

• Verify that the Label Top (

^LT) command is correctly set for your application (consult the

ZPL Programming Guide).

A receipt format was sent to, but not recognized by, the printer.

• Is the printer in pause mode? If so, press the Feed button.

• If the status LED is on or flashing, refer to What the Status Light is Telling You on page 92.

• Make sure the data cable is correctly installed.

• A communications problem has occurred. First, make sure that the correct

communications port on the computer is selected. Refer to Communicating with the

Printer on page 49.

• Verify the correct Format and Control Prefix on the printer match what you are using in

your ZPL programmed label format. The default Format (COMMAND CHAR) is Caret

(^) character and the Control (CONTROL CHAR) is a Tilde (~) character. Verify the

characters with the Configuration Status label printout. Refer to the one-flash sequence of

Feed Button Modes on page 31 to print this label.
