Interior Cleaning

To clean the interior of the printer perform the following steps.

1.Power off the printer and unplug the printer power cord.

2.Open the printer cover. Fully raise the forms thickness lever. Unload paper.

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. To avoid corrosion damage, use only alcohol when cleaning the printer mechanical elements. Solutions used to clean mechanical elements must contain no water.

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.

7.Using a soft cloth lightly moistened with anhydrous alcohol, 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.

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

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

10.Install the ribbon and load paper.
