of the above models.

Execute the image check and adjustment in the following sequence.
copy.  (Single 
! Single)
! Single)
Preparation of test chart for SPF
  a. Use A3 standard paper.
  b. Draw a line across the paper to indicate the full width in order to allow checking of void and image loss.
  c. Put marks to indicate up and down and back and forth.
  d. Draw the centreline across the paper to indicate the full length in order to allow checking of off-centre.
  4) Check the output copies for image distortion, void, lead edge position, off-centre, magnification ratio, dirt,
etc.
  5) If there is no problem in the output copies, the image check is complete.
(2) Locating the problem section
  1) If there is no problem in the output copies, perform self-printing to locate the problem section (the scanner
section or the engine section), which needs an adjustment.
Note:
To check images of self-printing, use the diag mode (TEST PRINT) of the engine side.
The self-print pattern varies depending on the adjustment item. Refer to the adjustment procedures
described later.  (When performing checking and adjustment of the image position, do not use the
output chart of SIM 64-1.)
* If there is any problem in the copy image and no problem in the self-print, an adjustment is needed on the
scanner section.
If there is any problem both in the copy image and in the self-print, an adjustment is needed on the engine side.
Note:  When SIM mode is inputted during execution of the diag mode, a malfunction may occur. In such a
case, turn off and on the power and input the SIM mode.
