Now compare the Printer Diagnostics pages. Look at section labeled
Adjustments. If the Top Margin and Left Margin numbers do not match
between the 2 Diagnostic pages they will need to be reset. To do this use
the following procedure:
1. Press the Online button to take the printer off-line.
2. Press Menu.
3. Press Next until <SERVICE> is displayed. Press Enter.
4. Press Next until <ADJUSTMENTS> are displayed, then Enter.
5. Press Next until <LEFTMARGIN> is displayed, then Enter.
6. Using the Next and Previous buttons, scroll to the desired margin
adjustment. Select Enter.
7. <TOPMARGIN> should now read on the Control Panel. Press
[Enter].
8. Using the Next and Previous buttons, scroll to the desired margin
adjustment. Select Enter.
9. Return the printer to online by selecting the Online button.
Finally, consult the Density Rate Setpoints section on the Printer
Diagnostics pages. If the 2 sections are different between the original and
new pages then a Color Balance procedure should be performed. Consult
the DocuPrint C55 User Guide or Technical Information Guide for details.
Note that even after performing a color balance procedure the Density Rate
Setpoints will not necessarily match the set points on the original Printer
Diagnostics page.
