2.2 Remedies for Maintenance Requests
This section describes the remedies for maintenance requests. Maintenance requests do not effect the printer’s operation; therefore, you can continue the current printing. When a
maintenance request error occurs, the printer displays on the LCD a hexadecimal code of “NNNN” which correspond to the bit numbers assigned to error statuses as shown in the
table below.
Note : Ex): When “Maintenance Request 0000048” is displayed.
As “0000048” in hexadecimal means “100 1000” in binary, you can find out the code is assigned to Bit-3 and Bit-6 referring to the above table. In this case, two errors are
occurring simultaneously. (Bit-3: battery exhaustion/ Bit-6: pump counter near end.)

DISASSEMBLY & ASSEMBLY Overview 52
SE Group Confidential (Related Staff Only)
3.1 Overview
This chapter describes procedures for disassembling the main components of SC-P800
series.
Be sure to follow the steps when disassembling the unit.
Unless otherwise specified, disassembled units or components can be reassembled by
reversing the disassembly procedure.
WARNING
Procedures which, if not strictly observed, could result in personal injury are
described under the heading “WARNING”.
CAUTION
“CAUTION” signals a precaution which, if ignored, could result in damage to
equipment.
CHECK POINT
Important tips for procedures are described under the heading “CHECK POINT”.
REASSEMBLY
If the assembly procedure is different from the reversed disassembly procedure,
the correct procedure is described under the heading “REASSEMBLY”.
ADJUSTMENT
Any adjustments required after reassembly of components or parts are described
under the heading “ADJUSTMENT”. Be sure to perform the specified
adjustments with reference to Chapter 4 “ADJUSTMENT”.
LUBRICATION
“LUBRICATION” signals that the part needs to be lubricated when replacing or
maintaining it after disassembling.
3.1.1 Precautions
Before starting the disassembly or reassembly of the product, read the following
precautions given under the headings “WARNING” and “CAUTION”.
W A R N I N G
When the PRINTR COVER is opened, a safety-interlock
mechanism causes the CR MOTOR and the PF MOTOR to
stop. When the interlock function is disabled, be sure to take
safety precautions and turn the function back to enabled after
the operation.
This printer is equipped with a lithium battery. When handling
the lithium battery, the following precautions should be
followed.
• When replacing the battery, replace it only with a specified
type of battery. Using a different type of battery may cause
excess heat or explosion.
Recommended battery: CR2032 (Sony)
• Dispose of used batteries according to manufacture’s
instructions and local regulations. Contact your local
government agency for information about battery disposal
and recycling.
• When disposing of the battery, be sure to securely cover its
(+) end with tape to prevent combustion or explosion.
• Do not recharge the battery.
• Do not use the battery if it is discolored or damaged, or if any
leakage of electrolyte is observed.
• Do not dismantle, solder or heat the battery. Doing so could
result in leakage of electrolyte, heat generation, or explosion.
• Do not heat the battery or dispose of it in fire.
• If the electrolyte leaked from the battery contacts with your
skin or gets into your eyes, rinse it off with clean water and
see a doctor immediately.

W A R N I N G
The power switch for this printer is installed on the secondary
side of the power circuit; therefore, the power is always
supplied unless the AC Cable is unplugged. To prevent electric
shock and circuit damage during servicing, make sure to follow
the instructions below.
• Before removing a circuit board, make sure to unplug the
AC Cable from the AC outlet and confirm the LEDs are
turned off by pressing the Power button on the Operating
Panel. This operation discharges the residual charge in the
printer.
• Make sure not to place the removed circuit boards on the
metal and such directly.
Always wear gloves for disassembly and reassembly to avoid
injury from sharp metal edges.
Never touch the ink or wasted ink with bare hands. If ink comes
into contact with your skin, wash it off with soap and water
immediately. If irritation occurs, contact a physician.
If ink gets in your eye, flush the eye with fresh water and see a
doctor immediately.
When replacing the MAIN BOARD, PSH BOARD, or Power
harnesses and such, make sure to check visually if any harness
is caught in between or any wrong connection exists.
C A U T I O N
Locate the printer on a stable and flat surface.
Use only recommended or s for disassembly, assembly or
adjustment of the printer.
Apply lubricants and adhesives as specified.
Be careful not to soil the printer or the floor with the leaked ink
when removing the ink-path-related components or parts.
Spread a sheet of paper or cloth on the floor in advance.
Do not touch electrical circuit boards with bare hands as the
elements on the board are so sensitive that they can be easily
damaged by static electricity. If you have to handle the boards
with bare hands, use static electricity discharge equipment such
as anti-static wrist straps.
When the printer has to be operated with the covers removed,
take extra care not to get your fingers or clothes caught in
moving parts.
When you have to remove any parts or components that are
provided as after-service-parts but are not described in this
chapter, carefully observe how they are installed and make
sure to remember it before removing them.
Disassembling the frame and some components (platen, PF
shaft) of the printer is prohibited because they are assembled
with precise measurements in 1/100 mm unit at the factory.

3.1.2 Cautions after assembling 3.1.3 Orientation Definition
The terms used for indicating the orientation/direction throughout this chapter are as
follows.
Figure 3-1. Orientation Definition
C A U T I O N
The ink-path-related components or parts should be firmly and
securely reinstalled on the printer to prevent the ink from
leakage.
When reassembling the printer, make sure to connect the
connectors of the electric components or parts correctly and
securely. Use extreme care when connecting FFCs (flexible flat
cables). Improper connection of the FFCs, such as inserting
them diagonally into the connectors, could cause shortcircuiting and lead to breakdown of the electric elements on the
boards.
When reassembling the printer, make sure to route the FFCs
and other cables as specified in this chapter. Failure to do so
may cause an unexpected contact of the cables with sharp metal
edges, or lead to lower the noise immunity.
When you removed any parts (especially cables) that are
secured with acetate tape or two-sided tape, be sure to reinstall
and secure them with the tape as exactly the same as they were.

Do not put the board directly on conductive surfaces with its
component side is facing down.
A lithium battery is pre installed on the boards provided as
service parts. Therefore, direct contact between the component
side of the board and conductive materials, or putting
conductive materials on the circuits must be avoided.

When removing the BOARD ASSY., POWER SUPPLY, do not
start the work immediately after disconnecting the AC cable.
Wait for at least five minutes for the electrolytic capacitor to
finish discharging residual charges.
When performing
Step 3 to Step 4, be careful not to disconnect
the cable forcibly from CN2 on the board as the cable is
directly-mounted and it cannot be disconnected.

Do not disconnect/insert the FFCs from/into the connectors at an
angle. Doing so may damage, short, or break the terminals in the
connector resulting in a breakdown of the elements on the board.
Connect the FFCs to their correct positions matching the
numbers written on the FFCs with those printed on the board
as shown in
Figure 3-37 and Table 3-2.
Route the cables of the APG SENSOR (CN4) keeping them
from contact with the spring as shown below.
Secure the grounding terminal of the MOTOR, INK SELECTOR
together with the BOARD ASSY., SUB with the C.B.S. 3 x 6 screw
on the right.
