• Put the ESD wrist strap on your wrist. Connect the wrist band to the system ground point. This action
discharges any static electricity in your body to the printer.
• Hold the parts by their edge connector shroud. Do not touch its pins. If you are removing a pluggable module,
then use the correct tool.
• If possible, keep all parts in a grounded metal cabinet.
• Do not place the parts on the printer cover or on a metal table. If you need to put down the parts, then put
them into their packing material.
• Prevent parts from being accidentally touched by other personnel. Cover the printer when you are not
working on it.
• Be careful while working with the parts when cold-weather heating is used. Low humidity increases static
electricity.
Adjustments
Printer skew specifications
Abnormal skew printer correction
1 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 or spec, then the repair operator can
adjust the aligner at the repair station.
2 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. Go to
“Polygon and Oscillating printhead mechanical registration
adjustment” on page 266
