Test Pattern Image Mode - Ricoh C226 Service Manual

TEST PATTERN IMAGE MODE

7. TEST PATTERN IMAGE MODE
This function is used to determine which printer component is causing an
image problem on the master.
In this mode, the background pattern that is printed will cover the entire sheet
of paper.
Procedure
1. Place paper on the paper table.
NOTE: To reduce the thermal head load, use the smallest paper size
possible, i.e. the smallest paper width on which the faulty part of
the image problem can be printed.
2. Access SP mode.
3. Input No. 90 and enter "1". Then, press the Enter (#) key.
4. Press the Clear Modes key to leave the SP mode.
5. Carry out the master making process (an original is not necessary).
6. Make several prints and check the image.
NOTE: The SP mode No. 90 setting will return to the default (0) after the
above procedure.
Assessment
If the printout is normal, a Part A component is defective.
If the printout is abnormal, a Part B component is defective.
NOTE: This mode can be used in combination with SP mode No. 92,
Thermal Paper Mode.
