part at the center carefully enough. (Note: Be sure not to damage the code

connected to the sensor!)

SR Troubleshooting

Wipe carefully the surrounding part of the light-receiving part (Fig.3).

Pass the cleaning cloth through the region where the labels pass and, lifting up

the cloth slightly, move it back and forth several times (You can clean the form

edge sensor without removing the center sensor.).

Mount the center sensor and tighten the two slotted head screws.

Set the labels and the ink ribbon and then set the threshold value,

Clean the thermal head,

the center. (Use the cleaning

cloth or alcohol.)

When the positions of pay-off side

and take-up side of the ribbon are

not in a straight line, the ribbon is

creased and, as a result, a blur

occurs in a slanting direction.

Install the ribbon straightly (set

the both sides of the ribbon at the

center) and align the position o

the ribbon so as not to make a

wrinkle.

When no signs of improvement are shown,

replace the thermal head with a new one.

Ink Ribbon Comes Out

Stuck to the Label!!

Clean the thermal head and print labels with the

print density set to 0. See “1. How to Adjust

the Density”.

Check 1

One of the most common causes of this problem is that the ink ribbon is

fused into the thermal head because of a larger supply of energy than

necessary to the thermal head.

If the thermal head is broken, the replacement will solve the

problem. (See “How to Replace the Thermal Head”.)

If you do not have a spare thermal head and want

to continue printing labels even if the print

quality is deteriorated, follow the procedure

below. Head error is temporarily ignored. (Be

aware that the broken wiring in the thermal

head causes white vertical lines.）
