Epson 7000 service manual ADJ CAP Position, ADJ Check Skew

EPSON Stylus Pro 7000 Revision B

ADJ CAP POSITION

Use this function to check the actual capping position and correct the capping position parameter in the firmware if necessary.

There may be very small differences between printers. Although the difference may only be a few pulses closer or further on the linear encoder, this is necessary to correct for any differences between one mechanism and another.

1.Make sure "Adj Cap Position" appears on the LCD and press the Enter button.

2.The printer begins the HP detection sequence and automatically detects the capping position, adjusting the logical position if necessary.

3.After the adjustment process is finished, the detected distance between the HP and the capping position is displayed.

4.Do one of the following:

>Press the Enter button to update the capping position parameter and proceed to the next menu item, or

>Press the Pause button to avoid updating the capping position parameter and return to the beginning; “Adj Cap Position” appears on the

LCD

ADJ CHECK SKEW

When the band turns a predetermined amount (during printing), the printer detects the paper edge using the P EDGE sensor. This value is compared to the originally detected value for the paper-edge position to determine if the paper is feeding at a slant.

Any change you make to the Check Skew distance only affects service-related printouts; the skew-check operation for user printouts does not change.

1.Make sure "Adj: Check Skew" appears on the LCD and press the Enter button.

2.If the paper is not loaded correctly, "Reload Paper" appears indicating you need to properly load the paper. If the paper is set correctly, the printer initializes the paper.

3. After paper is loaded and initialized, "Check Skew 1.0m" appears. Use

the Paper Feed + and Paper Feed - buttons to adjust the paper-skew detection distance, then press Enter to begin the skew check.

4.After the skew is correctly detected, "Skew Result: xxxx" appears. Press Enter to proceed to the next menu item, or press Pause to return to the beginning; “Adj: Check Skew” appears on the LCD.
