2)Check that the Ribbon Cassette in use conforms to the Specifications. (ERC-38 or compatible)

3)Check the ribbon for bending, twisting or damage.

Replace the Ribbon Cassette if it is affecting print quality.

4) Check that the paper in use conforms to that described in the Specifications.

8-3-2-2 Periodic check

After every 6 months, the printer parts should be checked for wear. (cleanliness, deformation, remaining lubrication, installation status, etc,) If any unsatisfactory points are discovered, they should be replaced.

1)Check the printer interior for adhesion of paper dust or scraps. Dust, and other foreign particles, cleaning out any adhered particles with a vacuum cleaner (paying special attention to dirt in the vicinity of the detectors.)

2)Check all the springs for deformation, replacing any deformed springs.

3)Check the gap between Head unit and Platen Assy. If there is a malfunction, perform repair according to section Disassembly & Assembly.

4)Check the lubricant and adhesive status of all applications points, applying lubricant or adhesive as required according to section 8-4 Lubricants and Adhesive Application.

5)Check if printing, paper feeding, ribbon feeding and ribbon shifting are normal. If not, perform repair according to subsection 8-6-3 Repair guidelines.

6)Observe all of the functions and check for malfunctions due to wear or deformation of parts, paper jam. etc. If there is a malfunction, perform repair according to subsection 8-6-3 Repair gulde71nes.
