2.3 Disassembly and Reassembly

Cautions for disassembling and reassembling the printer are stated below.

As for the disassembly procedure, refer to the

Parts Catalog

. The illustrations in the

Parts Catalog

are numbered according to the order of disassembly.

2.3.1 Removing plastic parts

The printer has many plastic parts. When disassembling the printer, be careful not to

break or bend the plastic hooks. For details on disassembly and reassembly, refer to

the

Parts Catalog

Some plastic parts contain glass fiber to improve the rigidity for better

precision. Since these parts are less flexible, their plastic hooks are

especially easy to break. During disassembly, do not exert excessive force

on plastic parts with a screwdriver or other instrument.

2.3.2 Removing and installing tap screws

The printer uses tap screws to fasten the upper and bottom cases, the control board

and bottom case, the pick-up unit and bottom case unit, and the chassis platen unit

and bottom case. The removed tap screws will have residue from the mold in which

the internal thread was made. Since the residue may crush the screw threads, clean

off the residue from the tap screws before re-installing or use new tap screws.

2.3.3 Cable positions

Lay the cables connecting the motors, sensors, and control board according to the

stipulated position.

For positioning the cables, refer to the

Parts Catalog

2.3.4 Deformation of spur tips

Be careful not to deform the spur tips.

The spur contacts the paper after the printing.

If the spur’s tips are deformed, the contact area with the paper will become larger,

increasing the amount of ink on the paper transferring onto the spur tips which will

soil paper with dotted lines.
