No.Operation detailsErrors that may occur during executionTime
1Set auto paper loading mode on.---Approx. 5 sec.
2

Unlock the lock lever.


---
Screen for roll paper feeding guidance:
"The spindle lock lever is raised. Do you want to load roll paper? If you will not load roll paper, lower the spindle lock lever."  "

Approx. 3 sec.
3Install roll paper.

Spindle screen guidance: Set.
Not a normal error.
Spindle screen guidance: "The spindle lock lever is raised. Do you want to load roll paper? If you will not load roll paper, lower the spindle lock lever." does not disappear → Spindle detection is broken (sensor or a part for pressing is broken.)  

About 5 sec
4Lock the lock lever.



---
Close the lock.
"The spindle lock lever is raised. Do you want to load roll paper? If you will not load roll paper, lower the spindle lock lever."  

About 3 sec
5Judge the position of the paper support lock lever and guide to the correct position.
  • Lock lever position incorrect error
Approx. 4 sec.
6Move the paper support lock lever to the correct position.

---
If it is in the correct position, transition to the paper selection screen.

7Perform paper feeding from the panel.

---
If you press OK, paper feeding starts.
OK: Proceed
Cancel: Idle

Approx. 7 sec.
Prepare the paper feed path.
8







Enable paper feeding.









1Withdraw the roll to the paper pack, (path opposite to path for paper feeding: 1st is selected, but return 2nd to paper pack)Approx. 25 sec.
2

Adjust interface of the roll edge sensor (1st Roll Paper Edge Detection Sensor or 2nd Roll Paper Edge Detection Sensor that is active) by loading paper: Adjust sensitivity.

  • --- (Paper Detect Error)
3

Set the paper edge sensor to ON (set 1st Roll Paper Edge Detection Sensor or 2nd Roll Paper Edge Detection Sensor that is active to ON).

  • --- (Paper Detect Error)
4Drive the 1st roll (1st/2nd, side that is active)

The same error occurs for the 2nd roll.

5Set the paper edge sensor to OFF (set 1st Roll Paper Edge Detection Sensor or 2nd Roll Paper Edge Detection Sensor that is active to OFF).

---

61st paper feed driven strong nip (1st/2nd, side that is active)
7Release the driven.


8Nip the sub-driven.

9Release the raised jag roller / EJ drive jag roller.
10Drive the 1st roll (1st/2nd, side that is active)
11Feed the paper to the sub-driven paper nip distance.
121st paper feed driven release (1st/2nd, side that is active, but motor is together)
13Enable tension control: Roll motor load measurement (1st/2nd, side that is active)
14Unlock the CR Unit
15

Switch the PG.
<Position>:
Board paper: PG++
Other than board paper: PG+

16Feed the paper from after the PE sensor to the nip pause position when feeding.
17Driven nip
18Open the suction chamber switching division plate (44-inch only: 36/24 do not have a shutter motor)
19Stabilize the paper on the platen.Operate the suction fan.
9









































Set the paper posture.




































1Enable paper coordination detection.


Judge the paper thickness.
Look at PF nip sensor → If it is broken, a paper thickness error can be reset, but even if paper feeding is tried again, it will not be possible.

  • paper thickness error (paper type, Paper path difference or foreign material)
Approx. 49 sec.
2Operate the suction fan.

3

Switch the PG.
<Position>:
Board paper: PG++
Other than board paper: PG+






Move the CR.
4Pass light through → detect the light shielding using APG Home sensor
5Judge the current PG and release the PG → switch to the target PG
6

Feed the paper.

7Provisionally update the paper leading edge position.---
8

Feed the paper.


9Move the CR (move it to the position at which sensitivity adjustment of the PW is possible).
10

Adjust the PE sensor sensitivity.
 Board paper / cut sheets: UPE Sensor
 Roll paper: BPE Sensor

---
11Adjust the sensitivity of the PW sensor.
  • --- (Paper Detect Error)
12Rewind the roll paper to take up the slack.
13






Judge the paper posture (roll paper).

















Check for skewing based on the side edges.









Detect the side position at the home side.

Move the CR.
Move to the side detection start position.

Approx. 18 sec.

14

Move the CR.
Full-> Home

15Sub driven release

16

Feed the paper.

17Detect the side position at the home side.

Move the CR.
Move to the side detection start position.

18

Move the CR.
Full-> Home

19Calculate the skew amount.

Paper  feed error when checking /paper skew error does not occured

20Set the skew amount.---
21

Nip the sub-driven.
(Will not move if nipped. This operation is performed if the deskewing operation is performed)

22

Feed the paper.

23Update the real-time exterior shape measurement reference position.

---

10

Measure the paper wide.1Detect the paper home side position.
2Detect the paper home side position.
3Detect the pattern.Feed the paper.
Detect the pattern.---
4Renew the paper front edge information.---
5Update the reading result.---
6Detect the paper full side position.
7

Detect the top position at the full side.

8Calcurate the front edge parallelism.---
9

Renew the paper front edge information.
Does not cut and no error (if, for example, the paper is skewed, printing is started aligned with the upstream side of the paper)

---
10Calculate the paper width.---
11Set to the waiting state.1Move the CR to the standby position.Approx. 3 sec.
2

Feed the paper so that its leading edge comes to the paper feeding waiting position.

12Release the paper from on the platen.Stop the suction fan operation.

The following errors may occur depending on the timing. If an error has occurred, restart the printer (the printer will not recover if it is not restarted). If the power cannot be turned off, remove and insert the AC cable, and then turn on the power.
