Maintenance Counter Value
The Maintenance Page Count is used to track general printer usage. A print job containing a single printed side 
will increment the Maintenance Count by one while a print job containing two printed sides (a duplex print job) 
will increment it by two. Whenever this count reaches 300,000, the printer posts an intervention and a status 
indicator, 80 scheduled maintenance, that notifies the user that scheduled maintenance is recommended. 
To view the Maintenance Counter Value, touch Maintenance Counter Value from the Configuration Menu. 
The panel displays the current value of the maintenance counter as illustrated below:
Touch Back to return to the Configuration Menu.
After installing the required maintenance kit, reset this count to zero.

REGISTRATION
Print registration makes sure the printing is properly aligned on the page. This setting allows separate Left 
Margin settings for each media tray. (The Top Margin setting is the same for all trays.)
The Registration menu item enables you to: 
•Establish the Top Margin setting for all installed paper trays.
•Establish a unique Left Margin setting for each installed paper tray. 
By adjusting the Top Margin setting, you move the top margin of all installed paper trays either up or down the 
page. By adjusting the Left Margin setting of a specific paper tray, you move that tray’s left margin either to the 
right or to the left. 
Enter Configuration Menu. See “Entering Configuration Menu” on page 3-33.
Touch REGISTRATION from the Configuration Menu. The current margin settings appear on the LCD.

Perform a Quick Test. See “Quick Test” on page 3-10.
1Each increment of adjustment corresponds to:
•1 scan at 300 dpi for the Top Margin setting or 
•1 pel at 300 dpi for each Left Margin setting 
2Increasing the registration value moves text up the page and widens the top margin; decreasing the registration 
value moves text down the page and narrows the top margin. The entire image moves up or down the page; 
therefore, no compression or expansion of the image occurs to preserve the bottom margin. 
3Increasing the registration value moves the margin to the left; decreasing the registration value moves the 
margin to the right. The entire image moves left or right on the page; therefore, no compression or expansion of 
the image occurs to preserve the right margin. 
To change the value of any of the margin settings:
1.Touch   to the right of the appropriate margin setting. The panel displays the settings name in the 
header and   [settings current value]   in a menu below the header row. 
2.Touch   to decrease the value and   to increase the value. 
3.Touch Back to cancel and return to the Configuration Menu. 
4.Touch Submit to save the change, at this time an alignment page will print.
The device prints a Quick Test page from the appropriate paper tray. While the Quick Test page prints, 
Printing Alignment Page appears on the LCD. 
Quick Test
The Quick Test verifies that the Registration margin values of the devices default input source are set 
appropriately.
To print the Quick Test page:
1.Touch REGISTRATION from the Configuration Menu. 
2.Touch Quick Test. 
3.Touch Back to return to REGISTRATION. 
4.Touch Back again to return to the Configuration Menu.

The printer always uses media from its default input source to print this test, except when the default source only 
supports envelopes. In this case, the printer automatically uses media from Tray 1. To generate the most 
accurate and useful registration information, print the Quick Test on letter- or A4-size paper.
If the default input source is empty, the printer stops printing and Load [Input Source] with [Paper 
Type] [Paper Size] IR appears on the LCD.
While the Quick Test prints, Quick Test Printing... appears on the LCD. No buttons are active while the 
Quick Test page is printing. When printing finishes, the panel returns to REGISTRATION.

and treats the input source as a non-sensing source. The media size can be set by the operator panel or the 
data stream.Input sourceSize sensing
