Phaser 7700 Color Laser Printer Service Manual
If RegiCon Coarse Skew Fails
This indicates that the horizontal alignment is so far out of adjustment that a
manual adjustment is required before the diagnostics test routines for fine
skew can pass. Other possible problems; a Mark-On-Belt Sensor failure,
Developer, Developer Bias Voltage, Print Cartridge, or Engine Control Board
Failure.
■
Perform the Coarse RegiCon Initialization procedure on page 4-140.
This adjusts the horizontal alignment closer and allows RegiCon #4 to
pass.
■
After Coarse RegiCon Initialization is complete, perform RegiCon #4
(Coarse Skew Adjustment) again. Make the required adjustments.
Note
Adjustments should be made only if the skew correction
indicated is greater than +/- five clicks. A positive number
indicates clockwise (CW) adjustment is needed. A
negative number indicates a counter-clockwise (CCW)
adjustment is needed.
Adjustment screws are located behind the Waste
Cartridge, which must be removed for access. From left
to right, the adjustment screws are: K, C, M, and Y.
