Disassembly and Assembly
This chapter gives instructions to disassemble and assemble the product. Also, the text explains
maintenance and cleaning.

Lubricants

Lubrication is critical to retaining the printer at its initial performance level throughout its 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.
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).
The three types of lubricants used with this printer are G-15, G-36, and O-13.
