General Operation Sequence; Power On - Ricoh D124 Detailed Descriptions Manual

1.7 GENERAL OPERATION SEQUENCE

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 document.
The general operation sequence is composed of these steps:

1 Power ON

2 Scanning
3 Paper Feed
4 Printing
5 Cutting
6 Paper Exit and Job End
1.7.1 1 POWER ON
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.
Notes
 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.
 If the machine is accidentally unplugged from the wall power socket, or if a power
outage occurs during the cleaning cycle after power on, the cycle will not resume
from where it was interrupted after power is restored. You must do cleaning with
the user tools after power is restored.
