1.3.4 Borderless Printing Specification
AVAILABLE PAPER TYPE
For the paper types and sizes that support the borderless printing, see "1.3.2.1 Epson
Special Media Table" (p17).
ROLL PAPER CUTTING OPERATION
Printer driver
settings
Borderless The default printer driver setting is “Borderless”.
Single Cut
Cutting Operation Explanation
The top area may become slightly uneven
depending on the image since the print
operation stops while cutting the top edge of
the roll paper.
If the cut position is misaligned slightly, small
parts of the image may be shown on the top or
bottom of the adjacent pages. If this occurs,
perform “Adjust Cut Position”.
When printing only one page the operation
performed is the same as that for “Double Cut”.
When continuously printing multiple sheets,
the printer cuts 1 mm inside on the top edge of
the first page and the bottom edge of the
subsequent pages to avoid showing margins.
Printer driver
settings
Double Cut
Cutting Operation Explanation
The top area may become slightly uneven
depending on the image since the print
operation stops while cutting the top edge of
the roll paper.
The printed paper is approximately 2 mm
shorter than the specified size since the printer
cuts the paper inside the image to avoid
showing top and bottom margins.
After cutting the bottom edge of the previous
page, the printer feeds the paper, and then cuts
the top edge of the following page. Although
this produces 60 to 127 mm cut-off pieces, the
cut is more accurate.

When “Value” is selected;
Choose an adjustment between -0.70 and +0.70%. Selecting too small a value causes
dark bands; adjust the amount upward. Similarly, choosing too large a value causes
white bands; adjust the amount downward.
It is important to choose the appropriate amount of suction for the paper used in order
to maintain the correct distance between the paper and the print head. Choosing too
high a value for thin or soft paper will increase the distance between the paper and the
print head, causing print quality to decline or preventing the paper feeding correctly.
If this happens, lower the paper suction. The suction power is weakened when the
parameter is lowered.
Select “High” or “Extra High” if the paper wrinkles during printing.High

2.1 Overview
This section explains the basic procedure for troubleshooting problems on the printer
quickly and efficiently.
When carrying out the troubleshooting procedures, take a flexible measure following
your sales company's policy and considering the troubling situation.
2.1.1 Preliminary Check
Make sure to verify or perform the following basic items whenever servicing the
printer.
2.1.1.1 Before performing troubleshooting
Before troubleshooting, perform basic checks such as connection check of the power
cable and installation check of the ink cartridges.
2.1.1.2 Check for the usage environment
Check the user's usage environment.
Temperature/humidity of the installation site
(For the guaranteed environment, see P.14.)
Drivers/RIP that the user uses
Genuine media or 3rd party's media?
2.1.1.3 Recurrence check of the trouble
Check if the trouble the user claims recurs with the returned printer.
If RIP was used, check if the trouble recurs when the driver is used.
If 3rd party's media were used, check if the trouble recurs when a genuine
medium is used.
If 3rd party's ink was used, perform the repair according to the policy of each
local sales subsidiary.
If the F/W was not the latest, gain agreement with the user on the update of F/
W, and check if the trouble recurs when the latest F/W is used.
2.1.1.4 Check for the counter values/history
Download NVRAM and check the following with NVRAM Viewer. (For the check
method, see P.252.)
Counter history of the periodic replacement parts. (if any part's life is near.)
Printer's operating history (if any cause for the trouble exists)
Error history (the frequency/history of errors related with the trouble)
2.1.1.5 Test print check
For the trouble related with print quality, carry out “Test Print” and check the current
adjustment status. (For the procedure of test print, see P.260.)
Genuine ink or 3rd party's ink?
F/W version (the latest?)
Check also the following if necessary.
Phenomenon Check Item
The installation site inclined?
Any vibrating equipment near the site?
Bad print quality
Missing dots/bad print quality Near a conditioner's ventilation duct?

3.1 Overview
This chapter describes procedures for disassembling the main components of SCS30600 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.
The disassembly/assembly procedures are provided based on SCT7000 series. The procedures for SC-T5000 series/SC-T3000 series
are basically the same unless otherwise specified.
3.1.1 Precautions
Before starting the disassembly or reassembly of the product, read the following
precautions given under the headings “WARNING” and “CAUTION”.
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.

C A U T I O N
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.
Locate the printer on a stable and flat surface.
Use only recommended tools 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 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.
The terms used for indicating the orientation/direction throughout this chapter are as
follows.
