Chapter 15 Routine Service

3.Unlatch both ribbon spools and carefully lift them off the hubs. Raise the ribbon out of the ribbon path.

4.Using a soft-bristled, non-metallic brush (such as a toothbrush), brush paper dust and ribbon lint off the tractors, shuttle cover assembly, base casting, and ribbon guides. Vacuum up the residue.

Caution

Vacuum carefully around the hammer bank and surrounding area to

 

avoid damage.

5.Wipe the splined shaft with a soft cloth.

6.Check the ribbon mask and hammer bank cover for bits of torn paper or ribbon lint. Check the holes in the ribbon mask surrounding each hammer tip. Gently remove paper or lint particles with a wooden stick or pair of tweezers. (Do not pry or apply force to the hammer tips.)

7.Using a soft cloth lightly moistened with anhydrous alcohol (no water), remove dust and ink from the platen. (The platen is the thick silver bar behind the hammer bank cover that rotates when the forms thickness lever is rotated.) Clean the ribbon guides.

Caution

When cleaning the platen, be very careful not to get any alcohol in the

 

hammer bank, because alcohol will cause severe damage to the

 

hammer bank. Only a trained service technician should clean the

 

shuttle assembly.

 

 

8.Brush and vacuum up dust or residue that has accumulated inside the lower cabinet.

9.For cabinet models:

Wipe the lower cabinet interior with a clean, lint-free cloth dampened (not wet) with water and mild detergent, or spray the surfaces lightly with window cleaning solution. Dry the lower cabinet interior by wiping it with a clean, lint-free cloth.

10.For models with a power paper stacker:

Wipe all power stacker components using a soft cloth lightly moistened with anhydrous alcohol (no water) to remove dust.

11.Reinstall the ribbon and load paper. Refer to the LineJet Printers Quick Reference Guide.
