Adj Cap Position; Adj Check Skew - Epson StylusPRO 7000 Service Manual

EPSON Stylus Pro 7000

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
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.
