Fabric Cartridge (26-1482)

If the ribbon cassette is already installed, simply check to see that it is 
properly threaded between the paper and print head.

If the ribbon cassette is not installed, or if it must be replaced due to 
excessive wear, faint printing, etc., follow this procedure:

1. Set the Power switch to OFF.

NOTE: When you turn the power OFF, any information stored in the Printer's 
buffer will automatically be lost.

2. Remove the Top Cover and gently move the Penetration Control Lever to-
   ward the front of the Printer as far as it will go.

3. Gently move the Print Head towards the center of the printer.

4. Unlatch each side of the Ribbon Cassette by gently pulling the Cassette  
   Latch away from the Ribbon Cassette about 1/4" and lifting up on that 
   side of the Ribbon Cassette. Repeat for the other side.

5. Make sure the ribbon is between the Print Head and the paper. Tighten 
   the ribbon by turning the Cassette knob in the indicated direction.

6. Gently press the Cassette down until is firmly secured by the "stopper  
   claws".

Do not force the Cassette into place! If the Cassette is not properly fit-
ted, the Cassette knob will not match up with the shaft from the Carriage.
Do not force the Cassette down but fit it in gradually while turning the 
Cassette knob in the indicated direction.

7. Once the new Cassette is installed, gently slide the ribbon in between 
   the paper and the Print Head. Tighten the ribbon by turning the Cassette 
   knob in the indicated direction.

8. Move thee Carriage back and forth manually to check that the ribbon  
   advances properly. If the ribbon has not been properly fitted between 
   the paper and Print Head (i.e., into the Print Head Guide Bezel), the 
   Ribbon feed will not operate smoothly.

9. Move the Penetration Control Lever towards the rear of the printer.

10. Replace the Top Cover.

REMEMBER!! It is extremely important that the Print Head is as close to 
the paper as possible; otherwise damage to the Print Head may occur. 
Simply move the Penetration Control Lever towards the paper and move the 
Carriage back and forth until smudging occurs. Then gradually move the 
Print Head away from the paper until the smudging stops.
