Ricoh D133 MP9002

This test pattern is generated in the application input processing circuit in the IPU. The operation path is as follows:

Application input > Memory > Printer

This test pattern is primarily used for design purposes, but it can also be used to trace the source of problems beyond the IPU (in the application input) which are causing poor print quality.

1. Enter the SP mode and select SP2902-004.
2. Enter the number for the test pattern that you want to print and press [#]. (See the table below.)

   No.	Pattern
   0	Off
   1	Vertical Grayscale 20
   2	Horizontal Grayscale 40
   3	Horizontal Grayscale 20
   4	Horizontal Grayscale 25
   5	Caterpillar

3. When you are prompted to confirm your selection, press Yes to select the test pattern for printing.
4. Press Copy Window to open the copy window, then select the settings for the test print (paper size, etc.)
5. Press [Start] twice (ignore the “Place Original” messages) to start the test print.
6. Press SP Mode (highlighted) to return to the SP mode display.
7. Switch the machine off and on.
