6.7 PRINT REGISTRATION ADJUSTMENT

Perform the following adjustment(s) after replacing any of the following parts:
• Rollers and gears
• Polygon mirror motor
• Paper feed unit
• Paper side fence
• Memory All Clear
For more details about accessing service modes, refer to section 4.
NOTE: 1) Use the frame on the service mode print log for the following
procedures.
2) Place A4 or LT paper in all paper feed trays, since the print log is
available only in these sizes.
3) To change the paper feed tray for printing the print log, change the
'output tray' setting inside the print log mode of the service program
menu to the desired paper feed tray.
1. Turn on the machine while pressing the "On line" key and "Escape" key
together to enter the service mode. Use the "arrow" key until "PRINT LOG"
appears.
2. Print out the print log from the desired paper feed tray and check the margin at
all four sides. Adjust the registration to meet the specification given below.

3. Check the margin at the leading and trailing edges of the frame. If out of
specification, adjust with Sub Scan in the service program mode. This will
adjust the paper feed timing, and will affect all paper feed trays. If the setting is
moved in the plus direction, the top margin will be bigger.
4. Check the margin at both sides of the frame. If out of specification, adjust with
Main Scan in the service program mode. This will adjust the laser start timing,
and is individually adjusted for each paper feed tray. If the setting is moved in
the plus direction, the right margin will be bigger.
