RegiCon #1 Fine Skew Adjustment
This process uses sensors to examine the RegiCon image on the belt and report what
adjustments need to be made. A side effect of this test is that horizontal and vertical
alignments are automatically done (if the test passed).
The data output presents the skew screw adjustment values (some number of "clicks"
of the screw, either CW or CCW direction). Values less than 5 or so are "noise" and
should not need to be adjusted.
1. From the Hidden Service menu, highlight the RegiCon Setup Cycle menu
and press OK.
2. The first time any RegiCon test is requested, the pages used to perform the test
must be created, so there is a short delay. During this time the front panel displays
“Processing Data - Please Wait”
3. Highlight Do #1 Fine Skew Setup and press OK. The front panel now
displays: Testing - Please Wait.
4. Wait until the test results are displayed as follows:
Note
Only 5 lines will be displayed at a time under the Information header. Use
the arrow buttons to scroll down or up as required to see the rest of the data.
Note
If the block counts are not the same number as presented here, the printer has
a print-quality problem. See "Streaks in Direction of Paper Travel" on
page 5-17 to resolve the print-quality problems before proceeding further
with RegiCon.
5. If an adjustment is needed, adjust by the amounts displayed on the front panel
until all clicks displayed are 5 or less.
Note
If RegiCon #1 Fine Skew test fails, see "RegiCon #4 Coarse Skew
Adjustment" on page 6-10.
