An administrator controls how a jumper reset affects a device by configuring the jumper-related setting on the Security
Web page.
Note: Administrators can discourage tampering with the jumper by securing the entire RIP card cage (of which the
jumper is a part) with a Kensington lock. Alternatively, to completely negate the effects of a jumper reset, an
administrator can select the
No Effect value for the jumper-related setting on the Security Web page or in the
Security Reset Jumper setting in the Security Menu .
To perform a jumper reset operation:
1
Power the device off.
2
Remove the Kensington lock from the card cage (if installed).
3
Remove the small yellow jumper that covers a pair of the jumper’s pins.
4
Replace the small yellow jumper so that it covers the pins adjacent to its original position.
5
Replace and secure the Kensington lock on the card cage (if installed).
6
Power the device on.
Note: The movement of the small yellow jumper from position A to position B triggers the reset, not the specific
positions. When the device is powered on, it labels the current position of the small yellow jumper (for example,
position A) as the “home” position. If, at the next POR, the device detects that the small yellow jumper has moved
from its previous home position (position A) to the other position (position B), then it performs a jumper reset. After
performing the reset, the device also relabels the other position (position B) as the home position (position A is now
the other location).
Note: The admin's security settings are lost when the RIP card is replaced. Secure settings are those that are
configured under the Settings > Security > Edit Security Setups menu. These are all the PINs, Passwords, and other
Building Blocks and Security Templates that define the protection of the functions and menus. In other words, if the
customer is using LDAP to authenticate users to use the Copy function, then after the RIP card is replaced, the LDAP
configuration and the Copy function will no longer be protected.
Printer skew specifications
Abnormal skew printer correction
STEP ONE: The repair operator should evaluate the left edge of the paper to determine if the aligner is properly set. If
the left vertical line is with the defined limit, parallel to the edge of the paper, the aligner is correct and properly set.
If the left edge vertical line is not within the defined limit spec the repair operator can adjust the aligner at the repair
station.
STEP TWO: The repair operator should evaluate the horizontal line at the top edge of the page for potential LSU induced
skew. If the horizontal line does not fall within the defined limit or spec, then it is considered skewed and the printhead
must be adjusted. See
“Polygon printhead mechanical registration adjustment” on page 284 .
