• Results will be stored as described in memory filed.
• The contents in SRAM are deleted when the test starts, and values detected at the normal
competition or until the apparatus stops due to errors are written.

Adjustment of Media Thickness Sensor

SRAM
This self diagnosis is used for adjusting the media Thickness sensor.
Notes! Check the Zero point output of Media Thickness Sensor in advance.
① Display the Paper thickness sensor output with 5.3.2.3 Switch Scan test.
Remove all papers at paper feed route as of now.
② Check paper thickness sensor output is 260h to 300h or not.
SRAM
③ If out of range, carry out a Zero point adjustment of Media Thickness Sensor.
For the adjustment, four sheets of a media whose Thickness(It is more desirable for measure
by micrometer) has been specified in advance are required. (Three sheets are required for
SRAM
the adjustment and one sheet is required for the check after the adjustment.)

In order to execute this adjustment (MEDIA WT ADJUST PA), stack the above media in order
in advance (No.1 and No.2 in order from the above four sheets in total) and then set the
media on MPT.
