Recommended Cleaning Schedule
Printhead
Interval: Clean the printhead after every 5 rolls printed.
Procedure: Cleaning the Printhead
Standard Platen (Drive) Roller
Interval: As needed to improve print quality. Platen rollers can slip causing print image distortion and in
worst case scenarios not move the media (labels, receipts, tags, etc.).
Procedure: See Platen Cleaning and Replacement.
Note • Standard platen rollers come in two colors, black (203 dpi) and gray (300 dpi).
Linerless Platen (Drive) Roller
Interval: If there is observed build-up of particles on the platen roller, use this procedure. The linerless
platen normally does not require cleaning. The adhesive side of the media picks up particles as you print.
If the linerless media is sticking and binding in the printer, the linerless platen normally needs to be
replaced. The silicon non-stick coating has been used up.
Important • Linerless platen rollers come in two colors, reddish-brown (203 dpi) and brown (300 dpi).
Important • Cleaning the roller with solutions or rubbing the delicate surface of this type of roller will
permanently damage or shorten the usable life of the linerless platen.
Important • The platen roller can accumulate adhesive on the outer edges of the roller. After using many
rolls of media, these ‘rings’ of adhesive can get dislodged when using the printer. These particle clumps
can then get transferred to other areas in the printer, most importantly, the printhead.
Procedure: To remove adhesive particles, use the adhesive side of a piece of linerless media to gently
press and remove the particles from the plater roller. Use the Platen Cleaning and Replacement procedure
to get better access for particle removal.
Media Path
Interval: Clean as needed.
Method: Clean it thoroughly with fiber-free cleaning swabs and cloths moistened with 99% isopropyl
alcohol. Let alcohol evaporate completely.
Procedure: See Media Path Cleaning.
