Lubricants
Lubrication is critical to retaining the printer at its initial performance level throughout its
product life, as well as avoiding potential problems. Always lubricate at prescribed intervals,
using the correct lubricants.
Standard Lubrication
❏ During disassembly and reassembly, clean the parts first, then lubricate them. See the
lubrication points table in this chapter and the lubrication and adhesive points diagrams in
the Appendix.
❏ Lubricate or overhaul after every 7.5 million lines printed.
Lubricants
The types of lubricants used greatly affect the printer’s performance and durability, and a
lubricant’s low-temperature characteristics require special attention. EPSON has conducted
thorough analyses of the technical data and wide-ranging experimentation on different
lubricants. The EPSON selection of lubricants prescribed for use with the printer is based on the
results of such research. The prescribed EPSON lubricants are available in 40 cc (40 gr) metal
cans or plastic containers (the smallest unit of supply).
Lubrication Points
The following table describes the lubrication points, type, and class. The numbers in the
following table correspond to the numbers in the lubrication and adhesive points diagrams in
the Appendix on pages A-7 and A-8.
