Inconsistent print quality, such as voids in the barcode or graphics, may indicate a dirty printhead. For the recommended cleaning schedule, see Table 1.
For printers with a peel assembly, keep the peel assembly closed while cleaning the platen roller to reduce the risk of bending the tear-off/peel-off bar.
Before touching the printhead assembly, discharge any built-up static electricity by touching the metal printer frame or by using an anti-static wriststrap and mat.
Open the media cover.
Release the printhead assembly.
As the printhead lever rotates upward, the printhead assembly pivots upward.
Remove the ribbon (if used) and the media.
Using the swab from a Zebra Preventive Maintenance Kit, wipe along the brown strip on the printhead assembly from end to end. In place of the Preventive Maintenance Kit, you may use a clean swab dipped in 99.7% isopropyl alcohol. Allow the solvent to evaporate.
The printhead may be hot and could cause severe burns. Allow the printhead to cool.
While manually rotating the platen roller, clean it thoroughly with the swab. Allow the solvent to evaporate.
The printer may perform a label calibration or feed a label, depending on your settings.
If performing this procedure does not improve print quality, try cleaning the printhead with Save-A-Printhead cleaning film. This specially coated material removes contamination buildup without damaging the printhead. Call your authorized Zebra reseller for more information.
