Figure T-7. Install the roller unit onto the printer
To replace the top cover, insert the tabs into the slots on the printer case.
Swing the front edge down to close the cover.
Leave the top cover closed during normal operation. The cover keeps out
dust and dirt and reduces the printer’s operating sounds. Open the cover only
to change the ribbon or make an adjustment.
NOTE : When you remove the color ribbon cartridge, press the ribbon
release catch toward you with your index finger. Once the ribbon is
free of the print head, the cartridge lifts out easily.
