Adjustments and Settings
TM-T88II Series printers are set up at the factory to be appropriate
for almost all users. There are, however, some settings for users
with special requirements.
Your printer has DIP switches that allow you to change
communication settings, such as handshaking and parity check, as
well as print density.
TM-T88II Series printers also have a near-end sensor for the paper.
This can warn you when the paper is almost out. If you find that
there is not enough paper remaining on the roll when the near-end
detector is triggered, you can change the near-end sensor setting.
See Appendix A, if you need to make any of these changes.

Troubleshooting
Troubleshooting
This chapter gives solutions to some printer problems you may
have.
General problems
The lights on the control panel do not come on.
Make sure the power supply cables are correctly plugged into the
printer, the power unit, and into the power outlet.
Make sure power is supplied to the power outlet. If the outlet is
controlled by a switch or timer, use another outlet.
Printing problems
The ERROR light is on (not blinking) and nothing is printed.
If the PAPER OUT light is on, the paper roll is not installed or is at
or near the end. Install a new paper roll. See Chapter 1 for
instructions.
If the PAPER OUT light is off, make sure the printer cover is
properly closed. Press the printer cover until the cover audibly
clicks into place.
The ERROR light is blinking and the printer does not print.
First, turn off the printer and check for a paper jam. (See the paper
jam description on page 3-3.)
Troubleshooting 3-1
If there is no paper jam and the printer has been printing for quite a
while, the print head may be overheated. If the print head is
overheated, the printer will resume printing when the head has
cooled (usually within two or three minutes).
If there is no paper jam and the print head is not overheated, turn
off the printer and turn it back on after about 10 seconds. If the
ERROR light is still flashing, contact a qualified service person.
The ERROR light is off, but nothing is printed.
Try to run the self test to check that the printer works properly. See
the self test instructions in Chapter 1 to run the self test. If the self
test does not work, contact your dealer or a qualified service
person.
If the self test works properly, check the following:
1. Check the connection at both ends of the interface cable
between the printer and the computer. Also make sure this
cable meets the specifications for both the printer and the
computer.
2. The data transmission settings may be different between the
printer and computer. Make sure the printer’s DIP switch
settings for data transmission are the same as the computer’s.
You can print the printer’s interface settings using the self test.
If the printer still does not print, contact your dealer or a qualified
service person.
Printing is poor.
Paper dust on the heating element of the thermal print head can
lower the print quality. Try cleaning the print head as described
below:
3-2 Troubleshooting
Cleaning the print head
CAUTION:
After printing, the print head can be very hot. Be careful not
to touch it. Also let it cool before you clean it.
Do not damage the print head by touching it with your
fingers or any hard object.
1. Open the printer cover.
2. Clean the thermal element of the print head with a cotton swab
moistened with an alcohol solvent (ethanol, methanol, or IPA).

Notes:
With the optional RS-485 interface, DIP switches 2-7 and 2-8 are disabled.
•
Changes in DIP switch settings (excluding switches 2-7 and 2-8 interface reset
•
signals) are recognized only when the printer power is turned on or when the
printer is reset by using the interface. If the DIP switch setting is changed after
the printer power is turned on, the change does not take effect until the
printer is turned on again or is reset.
If you turn on DIP switch 2-7 or 2-8 while the printer is turned on, the printer may
•
be reset, depending on the signal state. DIP switches should not be changed
while the printer power is on.
If the print density is set to level 3 or 4, the printing will be at low speed.
•
In a low power consuption, printing speed is fixed to 70 mm/sec.

using the interface. If the DIP switch setting is changed after printer power is
turned on, the change does not take effect until the printer is turned on again
or is reset.
If you turn on DIP switch 2-8 while the printer is turned on, the printer may be
•
reset, depending on the signal state. Do not change DIP switches while the
printer power is on.
If the print density is set to level 3 or 4, the printing will be at low speed.
•
In a low power consumption, printing is fixed to 70 mm/sec.

Changing the DIP switch settings
If you need to change settings, follow the steps below to make your
changes:
CAUTION:
Turn off the printer before removing the DIP switch cover to
prevent an electric short, which can damage the printer.
1. Make sure the printer is turned off.
2. Remove the screw from the DIP switch cover. Then take off the
DIP switch cover, as shown in the illustration below.
DSW1
DSW2
3. Set the switches using a pointed tool, such as tweezers or a
small screwdriver.
4. Replace the DIP switch cover. Then secure it with the screw.
The new settings take effect when you turn on the printer.
A-6 DIP Switch and Paper Near End Settings
Adjusting the Paper Near End Detector
FEED
The paper near end detector detects when paper is almost gone by
measuring the diameter of the paper roll. The detector has two
settings.
Because of variations in paper roll cores, it is not possible for the
detector to measure the exact length of the paper left on the roll
when the detector is triggered. Of the two settings, the factory
setting (lower) leaves the least amount of paper on the roll when
the sensor is triggered. If you want more paper left, change the
setting as described below.
Note:
The factory setting is based on a paper roll core with an outside
diameter of 18 mm (0.71") and an inside diameter of 12 mm (0.47").
If you use a paper roll with a core with an outside diameter of more
than 18 mm, it is better to change to the upper setting, as described
below.
1. Open the printer cover, and remove the paper roll.
2. Loosen the adjusting screw and move the tab up to the upper
setting.

detecting lever moves freely.
4. Replace the paper roll.
