Z  Series Cleaning

Exterior

The exterior surfaces of the printer may be cleaned with a lint-free cloth. Do not use harsh or abrasive cleaning agents or solvents. If necessary, a mild detergent or desktop cleaner may be used sparingly.

Interior

Remove any accumulated dirt and lint from the interior of the printer using a soft bristle brush and/or vacuum cleaner.

Refer to Table 1 for the correct interval for cleaning the printhead and platen roller. Poor print quality as represented by uneven print darkness, blank areas in bar codes or graphics, or illegible numbers and letters, may indicate a dirty printhead and/or platen roller.

Printhead and Platen Roller

Inconsistent print quality, such as voids in the bar code or graphics, may indicate a dirty printhead. For best results, perform the following cleaning procedure after every roll of ribbon.

Note: You are not required to turn off the printer power for this procedure.   Remove all rings, watches, hanging necklaces, identification badges, or other jewelry that could touch the print head or get caught in the printer.  If you turn off the power, you will lose all temporary settings, such as label formats, and you must reload them before you resume printing.

To clean the printhead, refer to Figure 1 and follow these steps:

  1. Open the printhead assembly.
  2. Remove the media and ribbon (if loaded).
  3. Using a swab soaked in the Zebra-recommended solvent, wipe along the print elements from end to end. (The print elements are on the brown strip just behind the chrome strip on the printhead.) Allow sufficient time for the solvent to evaporate.
  4. Manually rotate the platen roller and clean thoroughly with solvent and a swab.
  5. Brush/Vacuum any accumulated paper lint and dust away from the media and ribbon paths.
  6. Reload media and/or ribbon, and close the printhead assembly.

NOTE: If print quality has not improved after performing this procedure, 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.

 

Cleaning the Sensors

Brush or vacuum any accumulated paper lint and dust away from the printer sensors.  The reflective sensor, transmissive sensor, and ribbon sensor should be cleaned on a regular basis to ensure proper operation of the printer. For printers with the value peel and power peel option installed, clean the take label sensor and reflective surface on power peel.

Cleaning the Cutter Module

(Cutter option required)

Refer to Figure 3.

To clean adhesive off of the upper and lower cutter blades:

  2. Use a swab moistened with the Zebra-recommended solvent to wipe along the upper cutter blade.

  3. To expose the lower cutter blade, turn the cutter motor thumbnut counterclockwise until you see the "V"-shaped lower cutter blade.

  4. Clean the lower blade, following the instructions in step 2.

  5. Replace the cutter shield.

  6. When you have finished cleaning the cutter module, plug in and turn on the printer. The lower cutter blade will return to its correct operating positions.
