Installing The Ribbon Cartridge; Running The Self Test - Epson LQ-300 Manual

Installing the Ribbon Cartridge

Before installing the ribbon cartridge, make sure the printer
is turned off.
1. Open the printer cover to the upright position+ then pull it
up to remove it.
Never moue the print head while the printer is turned on; this
can damage the printer. Also, if you have just used the printer,
let the print head cool for a few minutes before you touch it.
2. Slide the print head to the middle of the printer.
3. Turn the ribbon-tightening knob in the direction of the
arrow to remove any slack from the ribbon so it is easier
toinstall.

4. Insert the ribbon cartridge into the printer as shown; then
press both sides of the cartridge down firmly to fit the
plastic hooks into the printer slots.
5. Use a pointed object, such as a ball point pen, to guide the
ribbon between the print head and ribbon guide. Turn the
ribbon-tightening knob to help feed the ribbon into place;
it should not be twisted or creased.
6. Slide the print head from side to side to make sure it moves
smoothly.
7. Re-install and close the printer cover.
When your printing becomes faint, you need to replace the
ribbon cartridge. To remove the old ribbon cartridge, first
move the print head to the center of the printer. Then grasp
the ribbon cartridge handle on either side and lift it out of the
printer.
