2. Adjusting the gap between the print head and platen
This adjustment allows for optimal print quality.
2-1 Measuring the gap between the print head and platen
1. Remove printer mechanism according to the procedure described in section 2,2.
2. Using the clearance gauge, measure the gap (backlash) between the print head and the platen.
Notice:
When adjusting, install the four rubber sheets in the printer mechanism.

3. Measurements are taken within the left and right printing areas of the platen.
Measure at 3 to 5 locations while rotating the PF roller. Be careful to prevent anything from altering
the accuracy of the measurements taken and to avoid any warped areas of the gum roller.
4. The standard gap should measure between 0.25 and 0.3mm (a range from 0.2 to 35mm can be
expected depending upon any variances).

2-2 Adjusting the gap between the print head and platen
Follow the instructions below if the size of the gap is not within the standard range.
1. Loosen the screws 1(in 2 places).
2. Adjust the head gap by rotating the adjusting washer (D). If using a jig, make adjustments from
above. If using a hexagon wrench, make adjustments from below.

3. Adjusting the Dot Alignment
This adjustment is made when the alignment of the print generated from left to right (outwards) does not
correspond with the print generated from right to left (inwards).
The acceptable range of displacement is a pitch of 1.
3-1 Adjustment A
1. Generate a print sample to assess the range of displacement.
2. Loosen the screw of the TM sensor board
3. If the print generated from right to left is off to the right, move the TM sensor board in the direction
indicated by the arrow 1. If the print is off to the left, move the TM sensor board in the direction
indicated by the arrow 2.
4. Tighten the screw of the TM sensor board.
5. Generate another print sample. If the print is still out of alignment, go back to step 2 and repeat the
above process.
6. If the print alignment does not improve, go to section 3-2 and go through the steps for Adjustment B.

3-2 Adjustment B
1. Remove the stop ring and idol gear as shown in Fig. 1-5.
2. Move the motor gear the equivalent of one tooth. Reattach the idol gear and stop ring. The position-
ing of the motor gear in relation to the idol gear is illustrated in Fig. 1-6 (refer to the placement of the
and symbols). (Make sure that the and symbols are not aligned.)
*If the print generated from right to left is off to the right, rotate the motor gear in the direction indi-
cated by the arrow.
3. Return to section 3-1 and repeat Adjustment A.

1. Maintenance
Carry out maintenance control items listed below to maintain the original performance of this printer and
prevent trouble from occurring.
1-1. Cleaning
(1) Removal of dirt.
Clean the dirt with tissure or soft cloth.
Note: Do not use thinners or trichlene/ketone base solvents for cleaning as they can damage
plastic parts.
Be careful not to damage electrical parts, wired areas or mechanisms and avoid getting
them wet.
(2) Removal of dust, pile, etc.
Clean with a vacuum cleaner.
Note: Check the amount of oil after cleaning and lubricate if necessary.
1-2. Checks
Maintenance checks for this printer is divided into the two areas of "daily check" that the person using the
printer carries out during normal use and "regular check" that can be done only by an experienced person
with a knowledge of the equipment.
(1) Daily check:
Check that the printer is being properly used.
•Is the ribbon cassette set in the correct position?
•Is the peper set correctly?
•Is there any dirt or foreign object in the printer?
(2) Regular check:
Carry out regular check and lubrication after six months use or after printing 1 million lines.
•Check for bending of springs.
•Remove any dirt or dust in the area of the detectors.
•Remove dirt around the drive shaft and lubricate.
•Check the gap between the platen and the print head.

2. Lubrication
Lubrication is extremely important for preserving the original performance of the printer over a long period
of time.
2-1. Type of oil
The type of oil used has a major influence on the performance and durability of the printer.You should pay
particular attention to the cold temperature properties of the oil. We recommend use of the grease and
lubrication oils listed below for this printer.
2-2. Lubrication method
When lubricating during disassembly or assembly operations, be sure to wash and clean the equipment
well prior to lubrication to remove dirt and dust.
Lubricate the equipment at regular intervals of six months or after every one million lines. Be sure to
lubricate equipment after disassembling or replacing parts when oil has been removed by cleaning.
