Note: After closing the platen frame and allowing the
rollers to contact each other, wait 5 minutes or
longer for the expansion and contraction of the
rubber material to settle. Then, measure the gap.

(1) With the front cover open, turn the power ON while keeping the RELEASE button pressed.
(2) Close the front cover and place the paper in the printer. en, the printer will print “Dot Alignment Adjust Mode” and
enter the impact head dot alignment adjustment mode. e printer will continue printing a total of 22 patterns of dot
alignment adjustments as shown below. e patterns are staggered in 1/8-dot increments.
e printed line above each pattern shows a number between 1 and 23 and its setting value (Lv.xx). e pattern preceded
by a “*” mark indicates the present setting value.
As shown below, the adjustment patterns that are printed consist of a three-dot bar each at the top and bottom for the
(3)
forward pass, and a three-dot bar in the middle for the backward pass. Check the patterns visually and select a pattern
with the three bars forming the straightest line.

Repeat step (4). At the pattern number that you wish to accept, keep the RELEASE button depressed (approx. 2 seconds)
until the buzzer makes a long (0.5 second) sound. is completes the acceptance of the setting.
Example: To accept the No. 4 setting, short-press the RELEASE button three times. At the fourth time, keep the
RELEASE button depressed.
Note:
This will cause the warning buzzer (0.1 second) to sound four times, and will delete the number of pressings
If you press the RELEASE button 24 or more times, it will exceed the available range of settings.

(6) If you do not find an optimal correction pattern among the printed patterns, perform the “Backward” or “Forward”
operation as indicated in No. 1. ese operations will allow you to make printing pattern adjustments with a greater
range of dot corrections. Aer performing steps (1) to (3), perform the respective operations as follows:
or a “Backward” operation, keep the RELEASE button depressed (approx. 2 seconds) until the buzzer makes a long (0.5

F
continue pressing and holding (approx. 4 seconds) the RELEASE button until the buzzer makes a short (0.1 second)
sound and another long (0.5 second) sound.
→
The printer will release the paper with a printing pattern in which the backward pass is corrected leftward of the
current printing pattern.
(7)
The printer will write the setting value, which you have accepted, on the nonvolatile memory. For confirmation, the
printer will print out ve patterns (which includes the setting value that you have accepted, as well as the preceding and
succeeding patterns) and an “Adjust Completed” message. is is followed by the release of the paper and the resetting of
the printer.
Note:During the period between the time you accepted the setting value and the printer starts to print as
described above, the printer will write the setting value on the memory. Never turn the power OFF or reset
the printer during this period. Doing so will corrupt the dot adjustment settings as well as other settings.
If you make a mistake in the settings, do not turn the power OFF in the middle of the process. Instead, wait
until the printer completes the nal reset and start the dot adjustment mode from the beginning.

Also, when installing the holder spring, be careful of
the following. (See the drawings at le.)
-
Be careful that the holder spring does not turn
along when tightening with the screw. It should
be mounted straight.
- Look from above the printer after tightening with
a screw to check that the half-cut of the frame is
securely in the hole in the holder spring.
- Check that there is adequate clearance (the area

To remove dirt from the surface of the platen of the thermal printer and the slip printer, gently wipe them with a
dry, so cloth. To remove dirt from other areas, use a so cloth or a cotton swab moistened with alcohol (ethanol/
methanol).
Note: Do not use thinner, trichlene or ketone solvents because they may damage plastic parts.
Also during cleaning, be careful not to moisten or damage electronic parts, wiring, or mechanical parts.
Removal of dust, pile
(2)
Vacuum cleaning (with an electric cleaner) is preferred. Remove all dust, etc., inside the printer.
Note: Aer cleaning, check the oil level. If it is not adequate due to cleaning, replenish it.
1-2. Checks
Checks must be carried out at two levels: “a daily check” which the operator can easily carry out during operation, and a
“periodic check” which an expert should carry out.
Daily check
(1)
When the printer is used on a daily basis, check that the printer is used properly. Make sure that the printer is
perating under the best conditions.
• Is the cartridge ribbon set at the right position?
• Is there any foreign matter inside the printer? (Remove if any.)
• Is the peper set correctly?
(2)
Periodic check
Aer 6 months or printing 1 million lines, the periodic check and lubrication must be carried out.
• Check for deformation of springs.
• Remove any debris, dust, paper particles, or glue from the rubber rollers, paper tray, paper guide, and sensors.
• Remove dirt around the drive sha and lubricate.
• Check the gap between the platen and the impact print head.
2. Lubrication
Lubrication is very important to maintain optimum performance and to prevent trouble.
2-1. Lubricant
e type of lubricant greatly aects the performance and durability of the printer, especially in a low temperature
environment. We recommend use of the grease and lubrication oils listed below for this printer.
Type of oilProduct nameMaker
GreaseMolykote EM-30LDow Corning Corporation
GreaseIsoex NBU-15NOK Klüber Co., Ltd.
GreaseFLOIL G347CAKanto Kasei Co., Ltd.
GreaseSankol CFD-5007ZSankei Kagaku Co., Ltd.
LubricantMobil 1Mobil Oil Co., Ltd.
2-2. Lubricating Method
When lubrication is carried out in assembly and disassembly, wash parts well to remove dust and dirt before lubrication.
Lubrication must be carried out regularly once every 6 months or aer 1 million lines have been printed. Lubrication is
necessary irrespective of the regular lubrication whenever lubricant becomes decient aer cleaning or whenever parts
have been disassembled or replaced.
