2. Lubrication
Lubrication is very important to maintain optimum performance and to prevent trouble.
2-1. Lubricant
The type of lubricant greatly affects the performance and durability of the printer, especially in a low temperature
environment. We recommend use of the grease and lubrication oils listed below for this printer.
Type of oil Product name Maker
Grease Molykote EM-30L Dow Corning Corporation
Lubricant Mobil 1 Mobil Oil Co., Ltd.
2-2. Lubricating Method
When lubrication is carried out in assembly and disassembly, wash parts well to remove dust and dirt before lubrication.
Lubrication must be carried out regularly once every 6 months or after 1 million lines have been printed. Lubrication is
necessary irrespective of the regular lubrication whenever lubricant becomes deficient after cleaning or whenever parts
have been disassembled or replaced.
