7. Detailed Description

Here is a brief summary of what happens when an original is scanned and printed with roll paper from

Roll Unit 1. Every phase of this operation summary is described in detail in later sections of this

The general operation sequence is composed of these steps:

3 Paper Feed

6 Paper Exit and Job End

1. The machine checks for paper jams, and issues a jam alert if one is detected.

2. The maintenance unit print head caps are lowered to uncap the print heads.

3. The horizontal motor switches ON and moves the carriage to the start position and then back to the

maintenance unit.

4. The positions of the print head OCFS feelers are checked to determine whether sufficient ink

remains in each sub tank.

5. The print head sub tanks are air purged and filled as needed and then the print heads are cleaned.

6. The print heads are capped.

7. The printer beeps twice when it is ready for operation.

• When the machine is powered on, especially after a cold start, the machine automatically checks

temperature, ink level, and air sensors. Then it cleans and re-fills the print heads. This can require

more time, depending on how long the machine has been off.
