3.4 CLEANING
3.4.01 General Information
An accumulation of paper dust is the most frequent cause of print quality problems in a dot
matrix printer. Small pieces of paper can cause paper jams. A dirty platen will smudge paper.
It is important to clean the printer regularly, paying particular attention to the printhead area and
the paper paths.
If the lubrication procedures are not performed properly, the printer will require more frequent
cleaning. Excessive lubricant attracts dust and accumulations build up quickly.
Keeping the covers in place and performing the cleaning procedures correctly will help ensure
the highest quality printer output.
