3.1.4 Test print by engine itself
Overview
This printer can perform test print as a operation check by engine itself. The printer
prints a test print pattern with built-in engine function.
Test Print Method
1. Remove the PWB Controller. (Refer to Chapter 4.2.19 "CONTROLLER
2. Put standard A4 paper in Tray 1 and turn the power ON.
3. Short circuit the 2 pins of the test print connector (P31) on the PWBA MCU &
HVPS. The location of the test print connector is shown in Figure 3-1.
NOTE:
Use some conductive object; like a tip of screwdriber to short-
circuit the pins.
4. After the printer has switch to READY Mode, start the print operation. (A
double-sided print operation will be performed.)
NOTE:
Refer to Chapter 2.7.2 "Operation Mode" about “READY Mode”.
5. To stop the print operation, remove the conductive object from the pins.
NOTE:
Tray 1 is set as the paper supply, so if there is no paper in Tray 1,
the print operation cannot be performed.
NOTE:
If the printer is in error state after power on, the print operation will
not start.
Figure 3-1. Test Print Procedure
Test Print Patterns
The test print pattern is printed at 600 dpi in a stair step pattern generated at
horizontal and vertical intervals of 128 dots for each of the black (K), cyan (C),
magenta (M) and yellow (Y) colors, in that order.
NOTE:
The lines printed in vertical direction (paper feeding direction)
becomes notched with this pattern. (This is not an irregularity with
the print out.)
