Cleaning the Printhead

Cleaning the Printhead

The KR403 kiosk receipt printer needs be cleaned periodically to maintain optimal print

quality and maximize printhead life. Even in the cleanest environments, the printhead will get

contaminates and build-up on the printhead’s pixel heating elements. These contaminates may

include: dust, body oils (acids), paper or media fibers, airborne chemicals, etc. Contaminates

shorten the printhead's usable life. Printing adhesive backed receipts or labels also add

adhesives to this list.

• Contaminates build up on the printhead over time, and get baked on the printhead's

heating elements.

• Contaminates also add to the normal friction wear between the media and printhead. They

can act like fine sandpaper and accelerate the wear process or even damage the printhead.

A basic and simple rule to use for ‘When do I tell the kiosk operator to clean the printhead’ is

to ‘Clean the printhead before loading a new roll of media’. Some media vendors secure the

end of the roll to the media core with tape or adhesive that can transfer to the printhead.

Always use a new cleaning pen on the printhead (an old pen carries contaminates from its

previous uses that may damage the printhead). The printhead can also be cleaned with a fiber-

free swab (such as a Texpad swab) or a lint free, clean, damp cloth very lightly moistened with

medical grade alcohol (90% pure or better).

When you load new media, you can also clean the printhead.

1. Open the printhead.

2. Rub the cleaning pen across the dark area of the printhead. Clean from the middle to the

outside. This will move contaminates to an area outside of media path and print area. This

will limit the amount of residual adhesive left on the printhead to non-functional area of

the printhead and platen (drive) roller.

Do not use the cleaning pen on anything other than the printhead to avoid cross-

contamination.

3. Wait one minute before closing the printer.

Basic Printer Cleaning for the Operator

Use a can of compressed air to remove dust and particle build-up from the printer. Open the

printhead and spray the dust out of the printer. Due to variations in kiosk design, media and the

individual kiosk’s installation environment; it difficult to recommend fixed cleaning period.

An arbitrary cleaning period should be once a month. Increase the frequency of cleaning if the

printer begins to have media sensing problems. Clean as required to remove build-up.

Caution • The printhead becomes hot while printing. To protect from damaging the

printhead and risk of personal injury, avoid touching the printhead. Use only the cleaning

pen to perform maintenance.
