Print Quality Problems

10. The printer is defragmenting memory.

Caution • Do NOT turn off the printer power during defragmentation. Doing so can damage

the printer.

•

Defragmentation is a normal operation of the printer – necessary to manage the memory

space for optimal use. The printer will defragment its memory both after a factory default

and when the printer detects that a defragment is required.

When the printer is in this condition, allow it to finish defragmenting. If this warning

occurs frequently, check the label formats. Formats that frequently and repeatedly write to

and erase from memory my cause the printer to defragment often. Using formats that avoid

frequent and repeated memory write/erase event will minimize the need for

defragmentation.

• If this warning condition does not go away, contact Technical Support. The printer

requires service.

Print Quality Problems

No print on the label.

• The media may not be direct thermal media. See the test procedure Determining Thermal

Media Types on page 36.

• Is the media loaded correctly? Follow the instructions for Automated Media Loading

on page 39 in the Operations section.

The printed image does not look right.

• The printhead is dirty. Clean the printhead.

• The printhead is under temperature.

• Adjust the print darkness and/or print speed.

•Use the

^PR (speed) and ~SD (darkness) commands referenced in the ZPL

Programming Guide.

• Manually adjust print darkness with the six-flash sequence of Feed Button Modes

on page 31.

• The Windows printer driver or application software may change these settings and

may require a change to optimize print quality.

• The media being used is incompatible with the printer. Be sure to use the recommended

media for your application, and always use Zebra-approved labels and tags.

• The printhead has worn out. The printhead is a consumable item and will wear out due to

friction between the media and printhead. Using unapproved media may shorten life or

damage your printhead. Replace the printhead.

• The platen may need cleaning or replacement. The platen (driver) roller maybe losing

traction due to:

• Foreign objects attached to its surface
