• SRAM Test
This test is used for checking the Random Access Memory (RAM) on the main PBA. If all memory is working
normally, the LCD shows TESTING OK!.
When this testing is carried out, any picture data stored in memory is erased.
• ROM Test
This test mode will display and check the current ROM level in your machine.
• DRAM Test
This test checks the DRAM memory status and shows if it is functioning properly
• Pattern Test
1. Select Pattern Test.
2. There are 4 different pattern tests. Scroll to the options by pressing Up or Down repeatedly until you find
the correct selection.
3. Press Select key.
• ADJUST Shading
This procedure is needed to set (make) a new shading reference value. The reference value is preset at fac-
tory. However, when a new CCD or main board is installed, the reference value must be set again.
Follow the next steps as instructed through the LCD window. After the shading value has just been set, the
shading value pattern is automatically printed. The shading value pattern shows the value of the white refer-
ence level of the Contact Image Sensor. Check for the waveform in the pattern. For best results the waveform
should be level. If there are many points sharply broken, perform the adjust shading procedure several times
until the waveform is level.
