3.5 LUBRICATION
3.5.01 General Information
If the lubrication procedures are not performed properly, the printer will require more frequent cleaning.
Excessive lubricant attracts dust and accumulations build up quickly. An accumulation of paper dust is the
most frequent cause of print quality problems in a dot matrix printer.
When lubricating the printer, refer to the lubrication diagrams on the following pages. Each lubrication
point lists a code for the type of lubricant to be used along with a code for the amount of lubricant required.
These codes are defined below.
