5. Gently pull the paper up through the paper slot. Be careful not to let paper perforations or sprock-

Replacing the Ribbon

Each printer is shipped with a standard black ink, one–inch nylon fabric ribbon on two spools. OCR
(extra dark) ribbons are also available. Replace the ribbon when the print contrast is too light or ap-
proximately after each box of standard size computer paper. To replace the ribbon, perform the follow-
ing steps and refer to Figure 2–4.
1. Place the printer off line and raise the top cover.
2. Fully raise the Forms Thickness Adjustment Lever (A) to open the platen. (To disable the audio
alarm, press the CLEAR switch.)
3. Unlatch the ribbon spools (B) and carefully lift them off the hubs (C). Raise the ribbon out of the
ribbon path. Discard the used ribbon.
4. Place each new ribbon spool (B) on a hub (C) with the ribbon to the outside. Either ribbon spool
can be loaded on either hub.
5. Press the spools down until the latch (D) snaps in place.
6. Thread the ribbon around the two ribbon guides (E) and through the ribbon path as shown in the
diagram (F) on the ribbon deck cover. The ribbon must pass between the two thin metallic strips
called the hammer bank cover (G) and the ribbon mask (H). Manually turn the ribbon spools to
ensure that the ribbon is tracking correctly in the ribbon path.
The ribbon must not be twisted. A twisted ribbon can lower print quality, shorten rib-
bon life, or cause paper jams.
