Printer Mechanism (M-4E60) Removal
1. Remove the upper housing. (See page 3-7.)
2. Remove the cables from connectors CN5 ~ 14 between the mechanism and C172 MAIN board.
3.
Remove 4 (CB 4 × 14) screws securing the mechanism to the lower housing.
4. Remove the mechanism from the lower housing by lifting it upward.
CAUTION
Never touch the white PF gears. Handling them will cause damage or contamination that
will affect print quality.
DISASSEMBLY / ASSEMBLY POINTS
❏ The mechanism unit does not have lubrication on the paper eject frame, where it contacts
the carriage unit. Therefore, you may want to put lubricant on it first. (See Chapter 6.)
❏ When mounting the printer mechanism, insert the shaft for the lower housing into the
hole in the ink cartridge holder cover, as shown in the figure below.
❏ Always connect cables to the same color connectors. (CN10 and CN14 have the same
color connectors but different cable lengths, and the cable for CN10 does not reach CN14.)
REQUIRED ADJUSTMENTS
❏ When you replace the main board, initialize EEPROM contents as follows:
1. Reassemble the printer.
2. Turn the printer on while holding down the Alt, LF/FF, Economy / Condensed and
Pause buttons on the control panel.
❏ When the EEPROM is initialized, some default settings (for example, the Bi-D setting,
head gap / angle / black-color head gap, head drive voltage settings, etc.) are lost. So,
you need to adjust the printer. (See Chapter 4.)
❏ When the EEPROM is initialized, the protect counter is also reset; so you need to replace
the ink drain pad. (See page 3-20.)
