CompTIA A+ 220-1201 (3.8 - Impact Printer Maintenance)

Printer ribbon replacement

• Single ribbon - Self-contained - One long circle

• Replace when ink becomes too light

- Ink is eventually consumed

• Designed to be modular - Replace in less than a minute

Print head replacement

• Takes a lot of abuse - Directly hits the ribbon and paper

• Gets hot - Watch your fingers

- Another modular part - Look for a release lever or bar

• Replace with the ribbon for the best effect

- The output should look perfect

Replacing paper

• Not as easy as a laser printer

- Paper must feed perfectly into holes

- Tractor feed

• Forms must be positioned correctly

- Text needs to fit a predefined space

• Paper must feed without constraint

• Make sure nothing is in the way
