CAUTION:
1. Lubrication: During parts replacement
2. Kinds of oil: FLOIL G-488: 1Kg can. (Part No. 19454906001)
3. Donotspraytheinside oftheprinterwithlubricants. Unsuitableoilcandamagethemechanism.
All machines are generally delivered in their best condition. Efforts should be made to keep them that
way. Lack of oil, or the presence of debris or dust, may cause an unexpected failure. To maintain in
optimaloperationcondition,periodicallyclean themachineand applytheproperkindsof oiltoeach part
in which lubrication is needed.
Although the frequency of lubrication varies according to how often the machine is used, as a minimum
it is necessary to lubricate before any part becomes dry. It is also necessary to wipe off excessive oil
or it will collect dirt.
WARNING!
Disconnect the power cord before replacing the main parts.

■Adjusting the Media Sensor Voltage
After replacing the driver PC board, be sure to adjust the sensor voltage using the procedure below.
When adjusting the black mark sensor, place IJ16 tag paper (OSAKA SEALING) so that the sensor
can sense the print area of the tag paper. For the feed gap sensor adjustment, place IJKS labels
(OSAKA SEALING).
(1) Connect the printer to a PC and turn the power on for both.
(2) Adjust the media sensor voltage.
■Black Mark Sensor
Fully turn the feed gap sensor adjustment knob on the rear of the printer counterclockwise.
Turn the black mark sensor adjustment knob so that the notch stops at a 180 degree angle.
TurntheVR3on thedriverPCboardineitherdirectionuntilalltheblackmarksensor lampsare
lit. Ifthe lampsdo notlight,turn theblack marksensor adjustment knobwithin theanglerange
of 150 degree to 210 degree, and retry.
■Feed Gap Sensor
Fully turn the black mark sensor adjustment knob on the rear of the printer counterclockwise.
Turn the feed gap sensor adjustment knob so that the notch stops at a 90 degree angle.
Turn the VR4 on the driver PC board in either direction until the topmost feed gap sensor
lamp lights. If the lamp does not light, turn the feed gap sensor adjustment knob within the
angle range of 60 degree to 120 degree, and retry.
NOTE: Adjust the knobs so that they stop in the mid-range with all the lamps lit.
(3) After completing this procedure, turn the power off.
